The truck suddenly loses energy and power while driving. This not only wastes fuel, but also wastes your time.
Poor quality engine oil contains more impurities, which is easy to cause filter blockage and wear of fuel injection nozzle plunger. The damage of the fuel injector will cause unstable acceleration, weak acceleration, or black smoke emission of the engine.
If the valve clearance is too small, the fuel in the cylinder is insufficient, resulting in reduced power; If the valve seal is not good or the clearance is too large, it is easy to cause pressure relief in the cylinder and reduce the engine power
Poor quality air filters and damaged pipes will make the intercooler dirty or even blocked, resulting in the failure of the intercooler to perform its cooling function normally, resulting in overheating of the engine, reduction of air supply and power decline.
The carbon deposit at the engine exhaust port is dark gray, with a layer of accumulated frost on the surface. The extremely thin carbon deposit indicates that the engine is in good working condition. The color of deposited carbon is black, bright but not wet, indicating that the engine has slight oil burning. Repair or replace. If the exhaust port is wet or there are traces of oil flow, it indicates that the cylinder is burning oil and should be repaired in time.
In addition, when the engine works normally, there is generally no smoke or some light gray white smoke, which is sometimes difficult to see with the naked eye. If black smoke is emitted, it means that there is more oil and less gas in the cylinder and the combustion is incomplete. If blue smoke is emitted, it indicates that the wear clearance between cylinder liner and piston, valve and valve guide is too large; If white smoke is emitted, it indicates that the fuel is mixed with water, or the diesel is not completely burned, which is emitted from the exhaust pipe after vaporization.
Checking the timing means checking the injection timing, that is, whether the fuel supply advance angle meets the requirements. If the fuel supply is too late, the engine is difficult to start, the combustion is incomplete, the exhaust pipe emits black smoke, the engine temperature is too high and the power is insufficient. If the oil supply is too early, there is a knocking sound when the engine is working, which will damage the parts, easy to reverse when starting, and will also affect the power of the engine.
Therefore, in actual use, regular maintenance and regular maintenance shall be carried out to ensure the normal use of the vehicle.
