1. The front wheel and toe are adjusted properly. Inaccurate toe will increase the rolling resistance of the car and increase fuel consumption. Check the toe value regularly and compare it with the normal value. If the value is different, adjust it.
2. Luyi bearings are well lubricated and properly adjusted. Poor lubricating grease and improper adjustment of bearing clearance will increase driving resistance.
3. Pay attention to the changes of the front and rear axles and the frame. Displacement or bending deformation of the front and rear axles and the frame prevents the body from sticking vertically or horizontally. When the car is driving, it steers to one side, and the tires and the ground slide friction, which increases driving resistance and increases fuel consumption. .
4. Pay attention to whether the leaf spring is damaged. The damage of the leaf spring makes the car poorly balanced, which increases the driving resistance and the fuel consumption also increases.
5. Adjust the brake clearance properly. If the brake clearance is too small and the resistance increases, you must open the throttle to run, which will increase the fuel consumption; if the brake clearance is too large, the brake will not work and safety will be affected. Adjusting the brake clearance to prevent brake stagnation and the gap being too large or too small also has an important effect on the sliding performance of the car.
6. Pay attention to the working condition of the clutch. The clutch is in poor working condition. During the transmission of torque, phenomena such as "trembling", "slipping", "incomplete separation" and "bottom" will occur, which will reduce transmission efficiency and increase fuel consumption.
7. Pay attention to whether the tire pressure is normal. The type of tire used should be the same. According to statistics, a 30% decrease in tire pressure from the specified value reduces the tire life by 33% and fuel consumption by 6%.
