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. If you are using a quality fuel filter like our, your filter should be out flowingthe fittings and fuel lines on your car by a considerable margin. Calculate your actual miles or kilometers, Ending Odometer Reading minus Starting Odometer Reading equals miles or kilometers traveled, End - Start = Miles or Kilometers traveled, Miles driven gallons used = miles per gallon =, Kilometers driven liters used = kilometers per liter = km/l. This information will be useless for what you are intending to do. Step 2: Input the no. Size for 12 Hour Run Time = Fuel Consumption x 12 hours x 1.1 Min. Thanks @saeed, the explanation of BSFC was very useful too. Often referred to as 'engine capacity,' this is the measurement of the total volume of the cylinders in the engine. Sorry can you explain what is MPG? Motor Vehicle Maintenance & Repair Stack Exchange is a question and answer site for mechanics and DIY enthusiast owners of cars, trucks, and motorcycles. It only takes a minute to sign up. Input Unit Type 1 = Inches 2 = mm : Bore Size : Stroke Size : Number of Cylinders: Rod Length . Does a diesel-like (ignition by compression) engine running on gaseous fuel exist? P.S. Step 2: Input the no. The default values are for distance 200 km, volume 200 liter and consumption 10 liter/100 km. You can probably get a serial number from thew OBD2 connector so people can have multiple profiles in the app, one for each vehicle. My 2.8L 6 cylinder Corrado was sleeker, heavier and vastly more powerful than my 1.8l 4 cylinder VW Golf. 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 anyway with this method the result is obsolete if car is stopped because 0km/h = no consuming :D :D (and it's wrong)maybe i can set some standard value if the car is stopped but the motor is on. Next choose a qualityfuel filter to match your line size that uses high flow high filtration media like our CM filters. About fuel level, yes you can see the % of fuel with PID 015E if i'm right. 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. @draksia, For emmisions sake when operating in closed loop, the A/F ratio is very controlled. For instance, let us determine the diameter of a cylinder for a 2-cylinder engine having a displacement of 200 cc with a stroke length of 150 mm. @ManiacZX, exactly. Let's set the unit for the engine displacement to cu in. 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. GVWR = gross vehicle weight rating. Calculate vehicle Understanding that is key for the correct interpretation and comparison of fuel consumption estimates such as those produced by this calculator. Or, will your fuel filter flow enough for my engine? l = liter(s). Fuel rate = price per liter divided by kilometers per liter @AdrianK You're very welcome, glad that it helped. 3) Need to know how far you get with certain RPMs for a certain quantity of gas. This is the total number of gallons or liters you used for the trip (or the time period). To calculate Fuel Consumption for a 400 hp Gas engine with a BSFC of .50 lbs/hp/hr: 400 hp x .50 = 200 lbs/hr To convert this lbs/hr to a more meaningful gallons per hour we use t he conversion rate from lbs to gallons which is 6.25 lbs to 1 gallon of gas 200 lbs/hr / 6.25 lbs/gal = 32 gph And that's it! 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. 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. (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). 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. In this application the stock line would not be able to flow much more then 60 GPH without significantpressure flow restriction accumulating. 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 I'm not sure how this gives the OP information about the PID they're requesting? Can I connect multiple USB 2.0 females to a MEAN WELL 5V 10A power supply? If we give each car of type A a liter of fuel, they will cover 5 kilometers combined while giving each car of type B a liter of fuel, they will cover only 4 km combined. Fuel is an additive to the air, not the other way around. is your source for information and insight on the world of engine oil and cooling systems. Suppose we're looking for optimum fuel consumption. Calculation (Litres used X 100) km travelled = Litres per 100km. Ever wondered what does cc or cubic inch written alongside an engine means or how to find cc of an engine? 2) Need to be able to estimate gas used at certain RPM. {{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. 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. 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. What is it costing you in fuel per kilometer? Check out 22 similar machines and mechanisms calculators . These things affect fuel efficiency, yes, but they are not things you can calculate. We can help you advertise its mpg. mpg US, 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. I have this weird misconception that the engine size is related to the amount of fuel being burned in one cycle(4-stroke engine). Side-by-Side comparison of cars and trucks. We can help you calculate and track your fuel economy. Gal = gallon(s). 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). It's possible to do that with the obd2 connected with the phone? Alternatively, you can calculate the diameter of the cylinder of stroke length using the engine displacement. With the space travel calculator, you can plan your journey to another star system or even another galaxy. Subtract the current fuel level from the last saved fuel level, that's how much fuel was used. How can I control PNP and NPN transistors together from one pin? I suspect the interface between that core API and your code would be the hardest part. In this application the stock line would not be able to flow much more then 60 GPH without significantpressure flow restriction accumulating. So basically, you could fit 1.3 Liters of fluid in the cylinder. The stroke length is the distance traveled by the piston inside a cylinder. Save my name, email, and website in this browser for the next time I comment. Why don't we use the 7805 for car phone charger? Our Engine Size and Fuel Consumption Calculator helps determine the size of an engine and its fuel consumption rate. https://www.calculatorsoup.com - Online Calculators. = price per mile. Can I connect multiple USB 2.0 females to a MEAN WELL 5V 10A power supply? Read about this at the piston force calculator and the engine horsepower calculator! of the trip), and update this figure every time you take a reading. Km percorsi = percurred km Step 1: Identify the number of cylinders and input the appropriate value as N = 4. Subscribe to The Canton Blog for ongoing access to: How to Estimate Your Engine's Required Fuel 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. If you are resetting your calculations every fillup, use this number. Using an Ohm Meter to test for bonding of a subpanel. = price per kilometer. The hot car calculator shows how fast a car's interior heats up during a summer day. 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? 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 $. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? If you are continuing your calculations from the last time the app was reset, add this amount to the previous fuel tally (but don't overwrite the previous fuel tally). Enter the price per gallon. Size for 8 Hour Run Time = Fuel Consumption x 8 hours x 1.1 Actual Tank Runtime = Actual Tank Size x 0.9 Fuel Consumption The fuel tank outlet shall not be lower than the fuel transfer pump Refer to the latest edition of NFPA 20 for all fuel tank and fuel line requirements 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. Listed below are the BSFC ranges for average efficiency Gas, E85 & Methanol engines at theirpeak hp output. We are not to be held responsible for any resulting damages from proper or improper use of the service. This way you will only need to multiply your horsepower by that figure to arriveat your GPH rate, without the need for converting from lbs to gallons after.
