Or how to find an engine's horsepower? In short, if you're trying to compare efficiency between two engines, size is not the deciding factor. 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]. 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. If so, its MPG = infinity for a while (i.e., not a good comparison). As I mention on outlet, was gonna just post as a comment because I did not have an answer. Then determine the line size and pump to support that flow. For further information, visit the cylinder volume calculator! INSTRUCTIONS:Choose units and enter the following: (R) Fuel consumption rate at idle (e.g. How to determine injector size for custom engine? Again we calculate Fuel Consumption for a 400 hp Gas engine. Fuel is measured in pounds instead of gallons. 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. Air/Fuel Ratio: The AFR defines the ratio of the amount of air consumed by the engine compared to the amount of fuel. How much air will an engine use per tank of gas? Therefore, engine displacement can also be referred to as: Engine displacement = No. The unit of measure here is lbs / hp / hr. in.). To learn more, see our tips on writing great answers. Can someone explain why this point is giving me 8.3V? At the end of your trip or week, fill up your tank again. Hahahahha sir your are the BEST. 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). Fuel rate = price per liter divided by kilometers per liter However, if you define efficiency as covering the greatest distance given a certain fuel amount, then the US researcher would be correct. The engine size and fuel consumption calculator works by using the following formula: The bore, stroke, and number of cylinders are inputs provided by the user and are used to calculate the engine size. Just use the fuel used and the distance travelled. Read about this at the piston force calculator and the engine horsepower calculator! of Cylinders, N = 4; bore diameter, D = 50 mm; and stroke length, L = 250 mm. Why in the Sierpiski Triangle is this set being used as the example for the OSC and not a more "natural"? Equivalent fuel economy/efficiency ratings are converted and shown for all units, mpg US, mpg Imp, km/l and l/100km. 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). BSFC is a great tool to quickly examine the relationship between fuel flow and horsepower. * D * L / 4 = Volume. 0.6 gallons per hour) (C) Cost of fuel (I) Time duration at idle 100% Load. hbspt.cta._relativeUrls=true;hbspt.cta.load(2368389, '09b67a15-b1f5-4f92-853a-9d4b0821002b', {"useNewLoader":"true","region":"na1"}); Topics: Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. 800 hp x .70 = 560 lbs/hr 560lbs/hr/ 6.59 lbs/gal = 84.98 gph, BSFC .70 / 6.59 = .106 gallons / horsepower / hour. What risks are you taking when "signing in with Google"? Because i can only read the % of fuel tank but not the total liters or Kg for CNG and GPL. have some suggestion? MPG = distance (km) x average gas consumption (litres) / 100 km However, it's much easier to use the MPG calculator. You will be able to modify the route by dragging the route line on the map.
