Therefore, Driving Resistance mus be reduced in order to save fuel.
Vehicle Driving Resistance Includes:
When a vehicle changes motion, it must overcome the inertia force which depends on the value of the vehicle acceleration and weight.
This is an inevitable natural force.
3. Air Resistance
This is primarily related to the vehicle’s aerodynamics, such as streamlined body design.
4. Mechanical Friction
This friction is inevitable and comes from the mechanical parts of the vehicle such as engine gear box, bearings, and brakes.
5. Tire Rolling Resistance – Driving Resistance That Is Ignored
Most people tend to ignore the 5th driving resistance – tire rolling resistance. However, it is actually the 3rd largest resistance that affects fuel consumption. When a truck in good condition is traveling at a speed of 80 km/h on a paved road, under standard load and pressure, about 26% of its power is used to overcome the tires’ rolling resistance. Therefore, the effect of tire rolling resistance on fuel consumption cannot be ignored.
