MPG Calculator - Estimate Your Gas Mileage Thanks @saeed, the explanation of BSFC was very useful too. People used to use cubic centimetres for engine size, but "litres" is easier to say and the number is the same anyway (albeit with a decimal in a different spot). Or how to find an engine's horsepower? Engine fuel consumption is something that is measured through experiments and recorded as a function of speed (RPM) and load (torque). How to calculate the force required to lift this deck? The money quote from Jeremy Clarkson was "It isn't what you drive that matters, it's how you drive it.". With regular driving the Air/Fuel ratio is kept constant at 14.7:1. What does the power set mean in the construction of Von Neumann universe? The size of the engine was insufficient to say "big = bad, small = good." Fuel makes power. Will higher octane fuel improve gas mileage? Fuel consumption is calculated by dividing the amount of fuel used during a certain distance traveled by the distance traveled. For example, a typical Formula One race car engine is of 1600 cc or 1.6 L capacity. miles per gallon (mpg) liters per 100 km (L/100 km) kilometres per liter (km/L) liters per mile. I try to use the MAF for calculating Fuel Consumption reading this Link but my car don't support the MAF PID, 0110 i get NO DATA response, so this formula is not good. 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 2006 - 2023 CalculatorSoup Alternatively, you can calculate the diameter of the cylinder of stroke length using the engine displacement. Here is an explanation why: if you were to take both cars of type A and want to cover 100 kilometers with each of them, you would need not 200 / 2.5 = 80 liters, but 125 liters of petrol (100 liters for the first car and 25 liters for the second). Imp (miles per Imperial gallon), 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 anyway with this method the result is obsolete if car is stopped because 0km/h = no consuming :D :D (and it's wrong)maybe i can set some standard value if the car is stopped but the motor is on. city or highway driving). Odometer at 1st fuel fill eg 1000km. 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. 565), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. That is unless there is already published data on this. It follows that type A is more efficient than type B using this definition. 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 By inputting the bore (diameter of the cylinder), stroke (distance traveled by the piston), and the number of cylinders, the engine size calculator can accurately determine the engine displacement. Fuel efficiency, or fuel economy, can be a tricky concept. 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. 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. Air Conditioner Brackets; Alternator Bracket Components; Alternator Brackets; . We are occasionally asked, what fuel flow do I need to support my application? QGIS automatic fill of the attribute table by expression. Each tool is carefully developed and rigorously tested, and our content is well-sourced, but despite our best effort it is possible they contain errors. How do rollercoaster designers calculate the ideal curve? The best answers are voted up and rise to the top, Not the answer you're looking for? What differentiates living as mere roommates from living in a marriage-like relationship? For example I drive a Ford Ka with a: 3) Need to know how far you get with certain RPMs for a certain quantity of gas. Note that it is associated with a unique speed and load combination. Fuel Consumption. See our full terms of service. {{vehicle.year}} {{vehicle.make}} {{vehicle.model}}, Hybrids, Diesels, and Alternative Fuel Cars, Tips for Hybrids, Plug-in Hybrids, and Electric Vehicles, Plug-in and Fuel Cell Vehicles Purchased in 2023 or After, Pre-Owned Plug-in and Fuel Cell Vehicles Purchased in 2023 or After, Plug-in and Fuel Cell Vehicles Purchased Before 2023. in. The engine displacement calculator can work backward. In short, if you're trying to compare efficiency between two engines, size is not the deciding factor. Search by MPG, price, make, body style, and much more with our. Answers to frequently asked questions about octane. Just ask the user what the fuel tank size is when they create a profile. So the question boils down to which engine has more friction per cycle, and which car has more weight to carry around. per HP FSW: 6.1 lb. 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. of cylinders * Volume of a single cylinder. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? 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 .
