Fuel consumption calculations are performed using this online calculator. Fuel economy is the amount of fuel / gas required to move a car / SUV over a distance.Fuel efficiency is the efficiency of converting energy contained in a carrier (car or SUV) gas /fuel to kinetic energy or work.Fuel / gas efficiency can mean the output one gets for a unit amount of gas input such as "miles per gallon" or "liters per 100 kilometers" for an car / SUV (sometimes called fuel . Generator Nameplate KW. Answers to frequently asked questions about octane. km/l and l/100km. Min. Is it feasible to Turbo a NA engine while maintaining 87 AKI octane fuel use? Find and Compare Cars in.). This filter features OEM style Fordfuel fittings specifically found on the 4.6 modular motor Mustangs. Why don't we use the 7805 for car phone charger? Note that the #of camshafts, #of valves and #of journal bearings also affect friction. Then you have a way of taking the engine size, RPM and historical average data and infer gas use real time. 3) Need to know how far you get with certain RPMs for a certain quantity of gas. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? Given, no. Fuel is an additive to the air, not the other way around. In short, if you're trying to compare efficiency between two engines, size is not the deciding factor. Answers to frequently asked questions about octane. Wir teilen auch Informationen ber Ihre Nutzung unserer Website mit unseren Social Media-, Werbe- und Analysepartnern. Clarkson was and is an entertainer. 440 lbs/hr. These are important questions whenselecting fuel filters, lines, and pumps for a performance engine. I'm not sure exactly what details are needed but wouldn't it be the size of the cylinder (bore and stroke) x cylinder size x RPM? The engine displacement calculator helps you determine the capacity or the cc value for an engine. (No, I didn't download you, but pretty sure this is the reason you were.). But i'm developing an application that read information with phone via the OBD2 port. Check out 22 similar machines and mechanisms calculators . At 18:1 you likely to get lots of NOx emssions and it 12:1 you get lots of unburned gas and other pollutants (see. in.). If it were me I would look at average driving habits (50/60kph in town + 100/120 highway) and get average RPMS at these speeds, and actual measured gas consumption per engine size. Step 1: Identify the number of cylinders and input the appropriate value as N = 4. Remember, if you arerunning E85 or Methanol be sure to use those BSFC values in your formula as well as the appropriate lb/gal conversion value for your chosen fuel.. To calculate peak fuel consumption for an 800 hp E-85 engine we can use a BSFC of .70 and a lb/gal of 6.59. 65mph and < 27mpg was more typical. Equivalent fuel economy/efficiency ratings are converted and shown for all units, The friction is measured in FMEP (friction mean effective pressure) which gives you the pressure required in the pistons to keep the engine spinning at a constant rate. If they did the test 20MPH slower it'd been a different story. Said another way, we know for each horsepower our gas engine creates we will need .50 lbs of fuel per hour. 800 0.55. And from obd2 i can't read mileage (for me km percurred)only the on board car computer can manage Km (distance). or i'm wrong? How to use the fuel efficiency calculator? Would you ever say "eat pig" instead of "eat pork"? The issue is what we care about when we calculate fuel consumption and fuel efficiency. Read about this at the piston force calculator and the engine horsepower calculator! Please confirm your calculations with your engineering or electrical team. The Absolute Fuel Consumption Value Fuel cost and CO2 calculator The Relative Fuel Consumption Per Distance Fuel consumption in liters per 100 kilometers The formula for calculating relative fuel consumption Relative fuel consumption in liter per 100 km calculator Online calculator - planning fuel consumption Fuel consumption in miles per gallon = diesel. PTO on. This website is administered by Oak Ridge National Laboratory for the U.S. Department of Energy and the U.S. Environmental Protection Agency. There are more things affecting fuel efficiency than the OBD2 connector can tell you about. The resulting fuel economy results were: That's the comparison between a 1.5 liter 4 cylinder vs. a 4 liter V8 and the bigger engine was significantly more efficient. How are you planning to address this? Jump to the compression ratio calculator to find out how! Looking for job perks? The French will see that for type A the average is 0.625 while for type B it is 0.5 and will conclude that type B is more efficient than type A, as the car will use less fuel to cover the same distance. You would need to sample many cars - perhaps crowd source it. Next choose a qualityfuel filter to match your line size that uses high flow high filtration media like our. In this application the stock line would not be able to flow much more then 60 GPH without significantpressure flow restriction accumulating. Instead, just get how much total fuel has been used (either from the last fillup or from the last app reset), just by: Don't worry about rpms, uphills, downhills, traffic, headwind, tailwind, sidewind, nowind, rain, snow, hot, dry, good tires, bad tires, stroke length, bore size, spark plug gap, or how long since the driver's last eaten meatloaf. The unit of measure here is lbs / hp / hr. These are very useful when estimating your fuel costs and can help you predict your expenses easier on a future trip. 100% Load. In short, the Prius was driven at its top (not very high) speed and the M3 remained right behind it for ten laps. if the fuel level went down, the car has been driven. Air Conditioner Brackets; Alternator Bracket Components; Alternator Brackets; . Imp (miles per Imperial gallon), However, the actual figure will vary dramatically. I read that is impossible to get distance traveled from obd2the only thinks that i can read from it (if my car support it) is the PID 015E = Engine fuel rate (L/h). running E85 or Methanol be sure to use those BSFC values in your formula as well as the appropriate lb/gal conversion value for your chosen fuel.. To calculate peak fuel consumption for an 800 hp E-85 engine we can use a BSFC of .70 and a lb/gal of 6.59. When you calculate miles/gallon (mpg) or kilometers/liter (km/l) you are calculating fuel economy in terms of distance per unit volume or distance/volume. https://www.gigacalculator.com/calculators/fuel-consumption-calculator.php, Avoid or reduce the use of air conditioning, Reduce the weight of the vehicle by not carrying excess cargo. Additionally, the fuel consumption calculator will output the fuel cost per mile or fuel cost per km, depending on the metric units selected, as well as miles per $ / km per $. Engines & Components . Next choose a qualityfuel filter to match your line size that uses high flow high filtration media like our CM filters. = price per kilometer. How do rollercoaster designers calculate the ideal curve? 4) Need to add fuzzy factor for terrain (hills, etc), weather (snow, wind, etc), gas type (high octain, etc), engines running off spec (leaks, etc). Then, an interesting problem needs to be solved: with the said speed (RPM) and load (torque), how fast can your boat go and carrying what load! Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Our online calculators, converters, randomizers, and content are provided "as is", free of charge, and without any warranty or guarantee. Thanks @saeed, the explanation of BSFC was very useful too. This parameter indicates the power generated by the engine and amount of fuel consumed. A narrowband O2 sensor tells the ECU if it is over or under stoichiometric mixing and it will adjust instantly. Save my name, email, and website in this browser for the next time I comment. Connect and share knowledge within a single location that is structured and easy to search. What does the power set mean in the construction of Von Neumann universe? @AdrianK You're very welcome, glad that it helped. happy to take advice using non-metric, but if so please just be precise in terms of what you're using (e.g. Regarding the small differences in the numbers between the methods, that is a result in rounding differences. fuel consumption in l/100km (liters per 100 kilometers). To learn more, see our tips on writing great answers. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Km percorribili = km that the car can percur with the remaining fuel. When you calculate liters per 100 kilometers (l/100km) you are calculating volume per 100 units of distance. wanna understand how those calculations are made, mechanics.stackexchange.com/questions/21434/, New blog post from our CEO Prashanth: Community is the future of AI, Improving the copy in the close modal and post notices - 2023 edition. Input Unit Type 1 = Inches 2 = mm : Bore Size : Stroke Size : Number of Cylinders: Rod Length . These calculations are essential for determining the efficiency of an engine and can help in making informed decisions when purchasing a vehicle or managing fuel costs. The cc in an engine refers to the engine displacement in cubic centimeters. Most people would argue that when we care about how much fuel we would need to cover a given distance. Note: These gph flow rates may seem high when compared to your daily driver on the highway, but remember these are not averages, these are flow at loaded peak output. To calculate Fuel Consumption for a 400 hp Gas engine with a BSFC of .50 lbs/hp/hr: To convert this lbs/hr to a more meaningfulgallons per hour we use the conversion rate from lbs to gallons which is 6.25 lbs to 1 gallon of gas. in. In such a case the French researcher is correct, as the average is misleading the US researcher. Air & Fuel Delivery. Step 3: The engine cc calculator will provide you with the bore diameter which is 23.15 mm. Given, no. The stoichiometric AFR depends on fuel type- for alcohol it is 6.4:1 and 14.5:1 for diesel. We can help you calculate and track your fuel economy. This is how to calculate your I'm not sure how this gives the OP information about the PID they're requesting? Is this plug ok to install an AC condensor? Step 1: Enter the engine displacement, V = 200 cc. To start the calculations for fuel consumption we use theBSFC (Brake-Specific Fuel Consumption)for the fuel being used. Is the Prius running on battery? Is this plug ok to install an AC condensor? "Signpost" puzzle from Tatham's collection, There exists an element in a group whose order is at most the number of conjugacy classes. So if a larger engine needs more air (more swept volume) per cycle then yes it will require more fuel. What are the advantages of running a power tool on 240 V vs 120 V. This is the total number of gallons or liters you used for the trip (or the time period). Now you have an approximatepeak gph fuel requirement for your engine that can guide you in choosing your fuel system components. What's the cheapest way to buy out a sibling's share of our parents house if I have no cash and want to pay less than the appraised value? "Mileage" is a generic term that means "distance travelled," it can be in miles or km, depending on the computer. Speed = Distance/Time, so Distance = Speed x Time. i get time monitoring using phone from start travel to lecture consuming and calculate the percurred km. anyway with this method the result is obsolete if car is stopped because 0km/h = no consuming :D :D (and it's wrong)maybe i can set some standard value if the car is stopped but the motor is on. Why did DOS-based Windows require HIMEM.SYS to boot? What is scrcpy OTG mode and how does it work? https://www.calculatorsoup.com/calculators/tools/gas-mileage-calculator.php. Estimate the fuel consumption rate by entering the kilowatt rating of your diesel or natural gas generator. Volume per distance fuel consumption is often used to compare the fuel efficiency of motor vehicles which have engines that run on liquid fuels such as petrol, gasoline or diesel. By knowing the amount of power your engine makes or is expected to make and the type of fuel you will be running you can calculateyour engine's required fuel consumption and flow. It's possible to do that with the obd2 connected with the phone? Our filter tests showed that in stock based applications with OE fittings andfuel lines in the 3/8 range thefitting and line size was the determining factor for flow. Understanding that is key for the correct interpretation and comparison of fuel consumption estimates such as those produced by this calculator. My idea is time query from obd and perform calculation for real time data. You have each researcher record the efficiency of 2 cars of each type, or, alternatively, the consumption of one and the same car in two different environments (the data available is the same for both), and the results recorded by them look like so: Average above means the arithmetic mean. But I think people would like the know their actual L/100 km. Fuel Consumption Calculator - liter/km Fuel Consumption Chart Use the chart below to estimate fuel efficiency. BSFC is a great tool to quickly examine the relationship between fuel flow and horsepower. Compare the gas mileage and greenhouse gas emissions of new and used cars and trucks Use this form to help you figure out your engine specs. You must have read about a 2 liter engine or a 100 cc motorcycle. Record the number of liters required to fill the tank. So was giving my answer from perspective of developer to developer. per HP | .40 lb. Does a password policy with a restriction of repeated characters increase security? miles kilometers (km) Fuel Efficiency. It is also a lesson on applying appropriate data transformations. Yes! It is important to note that this formula is a simplified version of the idling fuel consumption calculation and may not provide accurate results for all vehicles.The accuracy of the calculation will depend on . The above is an illustration of why when using our fuel consumption calculator, as well as other such tools, it is important to keep track of the end goal and define the question at hand precisely, before measuring and making conclusions. :), @Dario If you only have the percentage of fuel tank, then require the user to input the size of the fuel tank when they setup a profile for their vehicle. Advertisement 300-hp Diesel Engine Example GPH = (0.4 x 300)/ 7.2 = 120/7.2 = 16.6 GPH 300-hp Gasoline Engine Example Below is the Formula to Estimate Maximum Engine Fuel Consumption. of cylinders, N = 2; stroke length, L = 150 mm; and engine displacement, V = 200 cc. Product Tech. GPH = (specific fuel consumption x HP)/Fuel Specific Weight Constants | Gas | Diesel SFC: .50 lb. Will higher octane fuel improve gas mileage? If you can somehow get an indicative figure of the air-fuel ratio then you can calculate fuel consumption from there but I'm not sure you can find that. Fill up your tank with fuel before you start a long trip or the block of time you want to track. 2010 Ford Fusion hybrid-- terrible gas mileage. I have not been a "developer" for decades, but if you have access to the phone API for the GPS data, most of your hard work will be done. Manufacturer will give info like fuel consumption figures - have you looked for that info? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. It can do this because the filtration media is designed for high flow and the point of restriction is limited to the stock style fittings in and out which are short in distance. Fuel Cost Calculator. of cylinder as 2 and stroke length as 150 mm. Sorry can you explain what is MPG? If you need to magnify the effect, let some air out of the Prius tires and pump some into the BMW's. I know this is stupid but how does engine size relate to the amount of fuel being burned in one cycle. rev2023.4.21.43403. This information will be useless for what you are intending to do. 360 lbs/hr. Often referred to as 'engine capacity,' this is the measurement of the total volume of the cylinders in the engine. The above BSFC number tell us that our gasoline engine requires .50 lb of fuel per horsepower per hour. The hot car calculator shows how fast a car's interior heats up during a summer day. Then determine the line size and pump to support that flow. If it were me I would look at average driving habits (50/60kph in town + 100/120 highway) and get average RPMS at these speeds, and actual measured gas consumption per engine size. Use this fuel calculator to easily calculate the fuel consumption of a vehicle: car, bus, truck, etc. following a course of hard acceleration, turns and braking, can be driven to a crap MPG. For gasoline engines, the stoichiometric , A/F ratio is 14.7:1, which means 14.7 parts of air to one part of fuel. per gal. I need some particular Pids of OBD besides rpm, speed, fuel level and fuel type? I present as evidence exhibit A: the comparison between the BMW M3 and the Toyota Prius on the Top Gear test track. MPG = distance (km) x average gas consumption (litres) / 100 km However, it's much easier to use the MPG calculator. Wir verwenden Cookies um Inhalte und Anzeigen zu personalisieren, um Social-Media-Funktionen zur Verfgung zu stellen und unseren Traffic zu analysieren. At a steady 55, driven gently, the Golf delivered 35-40 mpg in California's Central Valley. When planning your fuel delivery system we recommend first starting with an estimate of the fuel consumption your engine will require. City percent must be a number between 0 and 100. h = hour(s). When you calculate liters per 100 kilometers (l/100km) you are calculating volume per 100 units of distance, or fuel consumption rate. @Dean, engines are sized in terms of the air volume to which fuel is added primarily because air is the dominant factor. Just use the fuel used and the distance travelled. We can help you calculate and track your fuel economy. Anyways I am see this a number of separate needs: 1) tank size and engine size, you need to basically be able to estimate used per stroke and how many strokes you have in the tank. Scroll down and read through our guide to understand better. For example, you may just want to track your weekly gas usage. How can "mpg" be high under low engine load? Thanks for contributing an answer to Engineering Stack Exchange! Step 2: Input the no. Trip Distance. This capacity is estimated based on the volume swept by the piston, i.e., the volume of a cylinder. Example: Using the engine size calculator. I suspect the interface between that core API and your code would be the hardest part. Ending Odometer Reading minus Starting Odometer Reading equals total kilometers, 100 * liters used kilometers driven = liters per 100 kilometers = l/100km. How to use the engine displacement calculator? four parts: f uel consumption of main engine(M/E), fuel consumpt ion of auxiliary engine(A/E), fuel con- sumption of marine boiler and fuel oil substitution for using s hore-to-ship power in port[4]. people talk online about "gallons" but not whether it's "US Liquid Gallon" or "Imperial"). I had gone through the manual on the boat - which didn't have the fuel consumption data; but after posting this I eventually found some sales info online which did have it, for different RPM. MPG stands for miles per gallon and, as this name suggests, it's the number of miles that a car can cover on a gallon of fuel. 2006 - 2023 CalculatorSoup Generic Doubly-Linked-Lists C implementation. Do simple math to get fuel efficiency since last fillup and last app reset (distance / fuel used = MPG, fuel used / distance * 100 = L/100 km), If the user inputs the distance needing to be driven for the entire Livello carburante = Tank level fuel For example I drive a Ford Ka with a: by converting the BSFC you preferfor your fuel from the normal lbs/hp/hr unit of measure to a gal/hp/hr measure. 0.6 gallons per hour) (C) Cost of fuel (I) Time duration at idle The calculation is performed as: D = ( (4 * V) / (N * * L)) = ( (4 * 200000) / (2 * * 150)) = 23.15 mm Side-by-Side comparison of cars and trucks. I don't mind down votes, just giving my opinion. Note that the km/l average is not misleading here, as it is 2.5 km/l, and 2 x 2.5 = 5, which is correct. This website is administered by Oak Ridge National Laboratory for the U.S. DOE and the U.S. EPA. This filter features OEM style Fordfuel fittings specifically found on the 4.6 modular motor Mustangs. Estimating Diesel Consumption. Sources ANL 1: Stutenberg, K., and Lohse-Busch, H. "APRF [Advanced Powertrain Research Facility at Argonne National Laboratory] Conventional Vehicles Snapshot Study." Litres are a measure of volume of any type, not just liquid quantity. Using an Ohm Meter to test for bonding of a subpanel. Record the trip starting odometer reading at the time you fill up. Why did US v. Assange skip the court of appeal? Making statements based on opinion; back them up with references or personal experience. Record the trip ending odometer reading (this might also be the starting reading for your next trip). Fuel is measured in pounds instead of gallons. A BMW throbbing along at a similar speed, driven perhaps not so hard because it would go faster or slower given the same inputs, will produce a happier MPG. Also save the odometer reading taken at this time. Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? A Prius howling along at 80 MPH with unknown hybrid system setup (no regenerative braking? Enter the price per gallon. of the trip), and update this figure every time you take a reading. The long length and twist and turns in the fuel line mean resistanceto flow is much greater. The fuel efficiency calculator estimates gas mileage based on the number of kilometers covered and the average fuel consumption of your car. Follow the steps below to know how to find engine displacement using our ingenious engine displacement calculator: Step 1: Count the number of cylinders for the engine, N. Step 4: The engine size calculator will return the engine displacement value in cubic centimeters (cc) or cubic inches (cu. We are occasionally asked, what fuel flow do I need to support my application? All other things being equal- same car body shape, mass, road, tires, cylinders, strokes, fuel/air system and ignition etc, a larger engine operating at middling RPM and power will require slightly more fuel to overcome friction than a smaller engine also comfortably operating at middling rpm and power. When planning your fuel delivery system we recommend first starting with an estimate of the fuel consumption your engine will require. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? highway fuel consumption and city drive consumption could replace Car 1 and Car 2 in the above table and produce the same result. How can I control PNP and NPN transistors together from one pin? Save this new fuel level for your next calculations, and store the previous fuel consumed tally if you plan on using it later. instantaneous Fuel F = 1 /(14.75 * 6.26) * MAF * t/60 instantaneous, Legenda translations: About fuel level, yes you can see the % of fuel with PID 015E if i'm right. Our engine size calculator is used to determine the engine size or displacement of an engine based on its specifications. 5) Need to know actual gas left in tank (don't have a way of figuring this out) so the app can use this and the above calcs to let you know if you need to fill up. With regular driving the Air/Fuel ratio is kept constant at 14.7:1. The result depends on the metrics used as input: miles per gallon if the input was in miles and gallons, and km per liter if the input was in kilometers and liters. The more pistons you have (V6 vs. I4) the more friction you will have. Example: To determine the deck height required for a 2332cc engine with a compression ratio of 9.5:1, and cylinder heads with a combustion . BSFC plots are like topographic maps: small round shapes inside larger round shapes, with each shape having a constant BSFC value.
