Listed below are the BSFC ranges for average efficiency Gas, E85 & Methanol engines at theirpeak hp output. BSFC measures the amount of fuel needed per horsepower per hour. FMEP times volume = Power per cycle needed to fight friction. Addiction calculator tells you how much shorter your life would be if you were addicted to alcohol, cigarettes, cocaine, methamphetamine, methadone, or heroin. 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? As others have implied, this mitigates all the "tire pressure/driving style/coasting/parked running" details and becomes a simple question of * calculated GPS distance/fuel % delta*. Our filter tests showed that in stock based applications with OE fittings and. per gal. You would need to sample many cars - perhaps crowd source it. 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. highway fuel consumption and city drive consumption could replace Car 1 and Car 2 in the above table and produce the same result. Given, no. "Signpost" puzzle from Tatham's collection, There exists an element in a group whose order is at most the number of conjugacy classes. MathJax reference. The difference there being the Prius was being driven flat out, way past what it was designed to do efficiently whereas the M3 was cruising along because it has the power and gearing to go much faster. 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. Engine size is calculated by multiplying the bore, stroke, and number of cylinders of an engine and converting the result to liters. How to determine injector size for custom engine? It is called Break Specific Fuel Consumption (BSFC) and it may be written in grams per kilowatt-hours of work done by the engine. It is called Break Specific Fuel Consumption (BSFC) and it may be written in grams per kilowatt-hours of work done by the engine.

Learn more about Stack Overflow the company, and our products. Has the cause of a rocket failure ever been mis-identified, such that another launch failed due to the same problem? 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 fuel flow and distance traveled are also inputs provided by the user and are used to calculate the fuel consumption. If you want to convert MPG as measured in US gallons into KMPL, the following equations are used: MPG = 2.352145836 KMPL KMPL = 0.425143707 MPG 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). What does that GPH rate mean for my Filter? How to combine several legends in one frame? Side-by-Side comparison of cars and trucks. Livello carburante = Tank level fuel In our testing this filter in isolation flows close to 100 GPH with around 1/2 psi resistance. Step 1: Enter the engine displacement, V = 200 cc. To calculate engine size, you can use the formula: For example, if an engine has a bore of 3.5 inches, a stroke of 4 inches, and 8 cylinders, you can calculate the displacement as follows: This formula can be used to determine the engine size or displacement of any internal combustion engine, regardless of whether it is a gasoline or diesel engine. For more in-depth advice, check out our list of ways to improve your fuel economy. 50% Load. Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? Connect and share knowledge within a single location that is structured and easy to search. GPH = (specific fuel consumption x HP)/Fuel Specific Weight Constants | Gas | Diesel SFC: .50 lb. I have this weird misconception that the engine size is related to the amount of fuel being burned in one cycle(4-stroke engine). This website is administered by Oak Ridge National Laboratory for the U.S. Department of Energy and the U.S. Environmental Protection Agency. Input Engine Displacement (L): The size of the engine, measured in liters.. Once you have this input, you can use the formula to calculate the idling fuel consumption in liters per hour. 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. Its important to note that these calculations are only rough estimates and actual fuel consumption can vary greatly based on the specific vehicle and driving conditions. Step 2: Input the no. Now you have an approximatepeak gph fuel requirement for your engine that can guide you in choosing your fuel system components. You can edit vehicles to personalize the MPG and fuel prices. The formula for calculating fuel consumption used in this online fuel consumption calculator is: Fuel consumption = Fuel used / Distance travelled. Step 2: Enter the bore diameter, D = 50 mm. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The depth of the cylinder, L can also be written as stroke length. It only takes a minute to sign up. The formula for calculating fuel consumption used in this online fuel consumption calculator is: Fuel consumption = Fuel used / Distance travelled 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. Compare to a Vittese with a straight 6 of larger displacement, they're going to be comfortable at two different speeds. For one heavy truck, the cost of idle fuel waste averages about $8,730. The engine capacity is measured in cubic centimeters (cc) and cubic inches (cu. You want to be sure that your componentscan delivererthe fuel needed to supply your thirsty engine. 0.6 gallons per hour) (C) Cost of fuel (I) Time duration at idle Calculate fuel economy in automobiles in US or Metric units. 440 lbs/hr. When a gnoll vampire assumes its hyena form, do its HP change? I read some Question like that but the best that i found is to fill the tank and read how many km you can do with that tank and register it. 360 lbs/hr. Jump to the compression ratio calculator to find out how! To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I need some particular Pids of OBD besides rpm, speed, fuel level and fuel type? To calculate engine size, you can use the formula: To calculate fuel consumption, you need to consider several factors, including: A commonly used formula to estimate fuel consumption is: Fuel flow can be estimated based on engine size, engine efficiency, driving conditions, and other factors. Compare the gas mileage and greenhouse gas emissions of new and used cars and trucks Step 3: The engine cc calculator will provide you with the bore diameter which is 23.15 mm. Usingour25-902 fuel filteras an example lets see how the filter fitting size and line size relates to flow. per HP | .40 lb. So I thought that in one cycle 1.3L of fuel is burned, but this is not the case so can someone please explain how they are related. Can someone explain why this point is giving me 8.3V? The unit of measure here is lbs / hp / hr. Input vessel, engine and transmission details and the program will calculate: Maximum achievable speed, estimated fuel consumption, recommended propeller diameter and pitch, a propeller pitch based on a required fixed diameter, plus it will suggest alternative propeller sizes using different gear ratios to provide better propeller effeciency. Find and Compare Cars 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. With regular driving the Air/Fuel ratio is kept constant at 14.7:1. When planning your fuel delivery system we recommend first starting with an estimate of the fuel consumption your engine will require. Below is the Formula to Estimate Maximum Engine Fuel Consumption. OP is a software developer clearly (see profile). The Corrado could touch 30 mpg under the same conditions, but only with constant attention to never having fun. The Cost to Idlecalculator computes the total fuel cost of idling an engine based on the fuel consumption rate at idle (R), the cost of fuel (C) and the duration of time at idle (I). 65mph and < 27mpg was more typical. Is the Prius running on battery? Check out 22 similar machines and mechanisms calculators . The car example uses as a basis one from Hand D. (1994) "Deconstructing Statistical Questions", Journal of the Royal Statistical Society, Series A, Vol.157-3:317-356. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. Or how to find an engine's horsepower? The calculation is performed as: D = ( (4 * V) / (N * * L)) = ( (4 * 200000) / (2 * * 150)) = 23.15 mm Also subtract the current odometer reading from the last time the app was reset, that is your trip distance driven. trip, your app can calculate the amount of fuel needed (at the start instantaneous Fuel F = 1 /(14.75 * 6.26) * MAF * t/60 instantaneous, Legenda translations: One of my vehicles has a fuel mileage thing included, and I was surprised at how much the instantaneous fuel efficiency changed from coasting to hard acceleration. I'm not sure how this gives the OP information about the PID they're requesting? 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. For an engine with N cylinders, each having the bore diameter, D and depth, L, the engine displacement can be written as: This formula is based on the cylinder volume formula. Equivalent fuel economy/efficiency ratings are converted and shown for all units, mpg US, mpg Imp, km/l and l/100km. An engine's BSFC can vary depending on load and RPM, these rates aim to represent the peak horsepower environment. A narrowband O2 sensor tells the ECU if it is over or under stoichiometric mixing and it will adjust instantly. Hi Chris, i don't need patent because a lot of people had same idea like mine :D :D . the problem is how to calculate the best consume during the travel. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. For example, a 1,000cc engine can hold one litre of air-fuel mixture and would be . Use this form to help you figure out your engine specs. If so, its MPG = infinity for a while (i.e., not a good comparison). Save this new fuel level for your next calculations, and store the previous fuel consumed tally if you plan on using it later. We can help you advertise its mpg. The US engineer will see that for type A the average is 2.5 while for type B it is just 2.0, concluding that type A is more efficient than type B as it can cover a greater distance with a liter of diesel, petrol, gas, etc. Our online calculators, converters, randomizers, and content are provided "as is", free of charge, and without any warranty or guarantee. My 2.8L 6 cylinder Corrado was sleeker, heavier and vastly more powerful than my 1.8l 4 cylinder VW Golf. km/l and l/100km. (miles left / MPG = gallons needed, km left * L/100 km / 100 = litres needed; if the amount of fuel needed is bigger than current fuel level, you will need to make at least 1 more fuel stop). @Dario "MPG" is the acronym for "miles per gallon," the measure of fuel-efficiency using Imperial units (miles and gallons). 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.
