Quick Answer: How is fuel consumption calculated in diesel engine?


How is diesel engine fuel consumption calculated?

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 calculate 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.

How do you calculate fuel consumption per hour?

Calculate your average speed by dividing the number of miles you traveled by how long it took you. For example, if you traveled 200 miles and it took you 4 hours, then 200 / 4 = 50 miles an hour on average. Divide your average speed by the miles per gallon to find how many gallons per hour of fuel you’re burning.

How do I calculate fuel usage per km?

The calculation is: litres / distance * 100 = l/100km. For example: 57 litres / 635 km * 100 = 8.98l/100km. If you know the price of fuel, then you can simply multiply the price per litre by the result and that gives you your cost per 100km.

What is specific fuel consumption of diesel?

The specific fuel consumption of an engine is the rate of fuel burnt to produce a unit of thrust. Improvements in fuel efficiency mean that the specific fuel consumption per kilometer driven decreased by more than 30 percent.

How far can a car travel with 1 litre of petrol?

The actual formula to get km per litre is 100 divided by 8 = 12.5 (Your car will give you 12.5 km on one litre).

What is 30 mpg in miles per litre?

Convert MPG to Litres/100 km

We have converted 30 Miles per Gallon to 9.4 Litres per 100 kilometres.

What will reduce fuel consumption?

Explanation: Harsh braking, frequent gear changes and harsh acceleration increase fuel consumption. An engine uses less fuel when travelling at a constant low speed. … Easing off the accelerator and timing your approach at junctions, for example, can reduce the fuel consumption of your vehicle.

How much fuel is in a horsepower?

On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower. Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower it produces.
