How to calculate accurate fuel consumption for Diesel engine by using OBD data?

How do you calculate the specific fuel consumption of a diesel engine?

Simple Method

  1. Formula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight. …
  2. 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
  3. 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

How do you measure fuel consumption accurately?

Divide total miles by total gallons.

For example, if you used 25 gallons of gas, and drove 500 miles during that time, then your average fuel consumption would be 20 miles per gallon (500 miles / 25 gallons = 20 mpg).

How do you calculate km per Litre of diesel?

You will need the number of litres it took to fill your tank since the last time you filled it, and the number of kilometres you traveled in between fills. The calculation is: litres / distance * 100 = l/100km. For example: 57 litres / 635 km * 100 = 8.98l/100km.

How do you calculate fuel consumption per km?

To work out how many kilometres your car drives on one litre of fuel simply divide the total distance travelled by the total litres of fuel used. Example: 400 km / 42 litres = 9.5 km’s per litre.

What is the formula for fuel consumption?

The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption. (Litres used X 100) ÷ km travelled = Litres per 100km.

What is the formula for specific fuel consumption SFC?

…of specific fuel consumption (SFC) for an engine producing gas horsepower is 0.336 (pound per hour)/horsepower, or 0.207 (kg per hour)/kilowatt. In actual practice, the SFC is even higher than this lower limit because of inefficiencies, losses, and leakages in the individual components of the prime mover.

How do I calculate fuel consumption in Excel?
For that I will first select my cell range. And enter the following formula equals to be five divided by C five. And I will hit ctrl + Enter. So the formula gets applied to the entire cell.

What is the rate of fuel consumption?

It is the amount of fuel consumed in driving a given distance. It is measured in the United States in gallons per 100 miles, and in liters per 100 kilometers in Europe and elsewhere throughout the world.

What formula is in Excel?


Formula Description Result
=A2+A3 Adds the values in cells A1 and A2 =A2+A3
=A2-A3 Subtracts the value in cell A2 from the value in A1 =A2-A3

How is fuel consumption calculated in India?

Fill the tank again and note the number of litres put in. Divide the number of miles driven by the amount of fuel used in litres (miles per litre) To convert the figure to miles per gallon multiply it by 4.544.

How do you calculate rate per km?

Let’s say, for example, that your trip computer (or the manufacturer’s website) says your specific car uses 8.0 litres of fuel per 100km. The actual formula to get km per litre is 100 divided by 8 = 12.5, meaning that your car will give you 12.5 km on one litre.
