The formula for calculating vehicle fuel consumption: Quantity of fuel added (L) ÷ kilometers traveled × 100 = 100 kilometers of fuel consumption.

The engine is set up on a stand, the ambient temperature is controlled, a fan is blown on the front side and a water load is put on the back side to simulate the driving condition of a car, and the data and curve charts of power, liter power, torque, cylinder pressure, intake and exhaust temperatures, and fuel consumption per 100 kilometers are controlled by a computer and calculated and drawn.

Expanded information:

On the special track of the special experimental car park, in the specified humidity, air pressure, tire pressure, etc., in the condition of fully loaded and equal speed (the scale weight is full of people and the back box with the weights);

Using the special measuring instruments ( With a graduated measuring cup, flowmeter, etc.) cut off the vehicle's original oil supply system, with a measuring instrument to measure the oil in the cup to run dozens or hundreds of meters (seems to be the case, do not calculate the acceleration of fuel consumption, can not skidding) of the back and forth after the road, divided by two calculated by 100 kilometers of fuel consumption, etc. The data.
