The engine is like the heart of the vehicle, and the wear of the engine is like the aging of the heart. The wear of the engine not only affects the normal operation of the engine, but also leads to a shortened life expectancy in severe cases. Therefore, it is very important for the maintenance of the vehicle to effectively and efficiently control the engine wear and keep the engine in good condition at all times. So what should be taken care of to reduce the wear of the engine? ◠ Use high quality engine oil When the engine is running, the metal surfaces inside the cylinder block run at a high speed of several hundred degrees Celsius and rub against each other, inevitably causing wear of the engine; especially if the truck is continuously running for a long time and the load is heavy, the wear may occur. Sex is even higher. High-quality engine oil can effectively control the wear of the engine. Not only that, it can also effectively suppress the generation of carbon deposits and sludge, thereby controlling the wear of the impurities on the engine surface in the oil passage. Many well-known brands of lubricants have good anti-wear properties. For example, Mobil Blackhead, which has just been upgraded to API CH-4, has excellent anti-wear properties. Wear is reduced, the engine's power is better and its service life is longer. ◠ Ensure that water and oil are in normal condition In addition, if you want to make the engine wear less, you need to pay attention to the status of the water/oil dashboard. In general, the water temperature should be controlled at about 80 degrees Celsius is appropriate, and the oil pressure gauge is displayed as 1 kg when driving at slow speed, and the express oil pressure is normal at 4-5 kg ​​when the express vehicle is running. If some vehicles are equipped with oil pressure lights, they should always pay attention to whether the oil pressure light is on. If the lights are on, it means that the status is abnormal and the driver needs to pay attention. ◠ Develop good driving habits Poor driving habits cause great damage to the engine. When driving, it is necessary to control the speed of the vehicle, correctly master the coordination of engine speed and gear, and avoid low-grade high-speed, high-grade low-speed. In addition, the vehicle should be running at a constant speed as much as possible, avoid stepping on the accelerator pedal and big foot brake during driving, and do not change lanes frequently. In general, 80 km/h is a more fuel-efficient and safe driving speed for trucks running high-speed road conditions.
