How is engine fuel consumption measured?

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 the fuel efficiency can be measured?

The calculation is simple. Divide the number of kilometers by the number of litres consumed. If you have covered 100km on the run and at refill, the vehicle has taken in five litres of fuel, your efficiency is 20kmpl.

How do you calculate L 100km?

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.

Is 7 km per liter good?

Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km. You'll often see it referred to as 'fuel economy'.

Do car manufacturers lie about mpg?

No, it doesn't. It emits what it emits (the calculation is simple – divide the number 6740 by the car's mpg for petrol engines, 7440 by mpg for diesel). This all adds up to taxman trickery and is, put simply, a con – a con on your wallets, on the taxman and on the environment.
