The fuel consumption of semi-trailers is abnormally increasing. What are the reasons?

What are the factors that affect the fuel consumption of semi-trailers? Engine horsepower, cargo capacity, road conditions, driver driving skills, and the degree of old and new semi-trailers are all related.

The horsepower of the semi-trailer head is different in fuel consumption. For example, the brands of tractors such as Auman, Shaanxi Automobile, and Steyr are different from each other, and the fuel consumption is different. The cargo load is also closely related to fuel consumption. The heavier the weight, the more fuel consumption. However, if the fuel consumption is abnormally increased, you should check the reason.

1, tire pressure problems. It is necessary to check the tire pressure of the semi-trailer regularly to see if it meets the air pressure standard. Generally speaking, the tire pressure is insufficient and the fuel consumption will increase.

2, tire wear. Regularly check the wear and tear of the semi-trailer tires. If the semi-trailer tires are seriously worn, it will often slip and increase the fuel consumption.

3. Check the bearings and brake system. Regularly check the semi-trailer bearings and brake system for malfunctions. If the wheel does not rotate properly, it will affect the speed of the car and increase fuel consumption.
