Most of our trucks are diesel engines. Of course, some light trucks and micro trucks are gasoline engines. I won’t repeat this. Diesel engine is widely used in trucks because of its large torque, simple structure and ability to adapt to harsh environment. In addition, the fuel supply system of diesel engine is simpler without spark plugs and ignition coils, so the stability of diesel engine is higher.
Because most of the faults of diesel engines are easy to judge, today I’ll tell you some methods of judging engine faults myself engine is faulty.
The first is that we can look at the instrument panel in our driving position. The faults displayed on the instrument panel are very accurate, so we should always check the parameters on the instrument during driving.
White smoke will also occur, mostly in the case of cold vehicles. With the gradual rise of engine temperature, the white smoke will turn light gray. If there is white smoke after the engine temperature rises, the engine will fail. If the exhaust funnel emits blue smoke, the engine should burn oil engine is faulty.
Fourth, we can disassemble and replace parts for comparison. If we doubt a certain part, we can replace the same functional part on the vehicle and compare it to see whether the fault changes with the change of parts.
The above mentioned are some small faults. Now most of our cars are electronically controlled engines. If we encounter difficulties, we still have to go to the manufacturer’s service station to repair them with professional tools. After all, the maintenance technicians are professional of engine is faulty.
There are many ways to check the engine fault. The key is to master all the knowledge of the engine, see each part of the engine and know its role. Finding the fault must be from simple to difficult. It can’t be overhauled. Only step by step can the fault be eliminated more easily.
