The engine is like the heart of man. It is absolutely vital to the truck.Small germs, if not taken seriously, often result in a loss of heart function, and this applies to trucks as well.Many car owners think that the regular maintenance of the truck is not a big problem, but it subtly affects the service life of the truck engine.Today, we will introduce to the majority of card friends a few easy to cause the truck engine hidden trouble small problems, I hope the majority of owners in the use and maintenance of trucks pay more attention to.

1. Unscheduled maintenance.

Regular engine maintenance is very important, and many professional mechanics report that poor engine maintenance accounts for 50 percent of all engine failures in their trucks.It is clear that engine maintenance plays an important role in extending the life of a vehicle.Not only do you repair your engine during regular service periods, but you also need to repair your engine components when driving in particularly wet or dusty areas.

2. The oil is bad and the oil filter is not smooth.

The quality of different grades of lubricants will change during use.After a certain range, the performance of the vehicle deteriorates, which can cause various problems for the engine.As the oil passes through the fine holes in the oil filter, solid particles and viscous substances in the oil accumulate in the filter.If the filter is blocked, the oil will not be able to pass through the filter element smoothly. The filter element will expand or open the safety valve and pass through the bypass valve. The dirt will be brought back to the lubrication part, leading to engine wear and acceleration and internal pollution aggravation.Therefore, it is equally important to replace the oil filter element regularly.Don’t reduce the oil, but don’t increase it too much.The more expensive international brand name synthetic engine oil, the better (because the global formula may not be suitable for Chinese models), the right engine oil for your car is best.

3. The air filter element is blocked.

The motor intake system is mainly composed of air filter element and intake pipe.According to different use conditions, the air filter element needs to be cleaned regularly.The air filter element is generally cleaned for 3 times and replaced with a new one. The cleaning period can be determined according to the air quality of the daily driving area.It is also very important to buy the original air filter element provided by the manufacturer with good quality.

4. The intake pipe is too dirty.

If the vehicle often in the dusty, poor air quality of the road conditions, should pay attention to clean the intake pipe, to ensure that the intake unimpeded.The intake duct is very important for the proper operation of the engine.If the intake pipe is too dirty, the efficiency will be reduced, leading to the engine can not operate within the normal output power range, aggravating the wear and aging of the engine.Try to walk less dusty areas, and pay attention to the replacement of air conditioning.

5. Too much sludge in the crankcase.

During the operation of the engine, the high pressure unburned gas, acid, moisture, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, making it mixed with the metal powder produced by parts wear and tear, forming sludge.A small amount of sludge can be suspended in the oil, and precipitate from the oil when the equivalent is large, clogging the filter and the oil hole, causing difficult lubrication of the engine, thereby aggravating the wear and tear of the engine.The selection of high quality fuel and synthetic diesel engine lubricating oil is particularly important to reduce the production of sludge, so it is recommended that owners try to buy synthetic diesel engine lubricating oil and fuel suitable for their cars through regular channels.In addition, please often check your car’s oil level, when insufficient should be replenished as soon as possible.

6. Improper maintenance of fuel system

Maintenance of the fuel system includes replacement of the gasoline filter, cleaning of the carburetor or fuel nozzles and fuel supply lines.Regularly remove the tank sediment, remove the fuel filter sediment, properly maintain the air filter, fuel tank and pipeline, clean the engine fuel system, use the engine does not remove the cleaning agent, use does not remove the cleaning agent does not need to remove the fuel system, on the one hand, play a role in cleaning the fuel system thoroughly

7, water tank rust, scaling

Engine water tank rust, scaling is the most common problem.To avoid the production of scale, it is necessary to pay attention to the selection of coolant in the water tank.Many owners do not pay attention to the use and quality of coolant, usually added to the tank is just ordinary water.The most common problems in cooling systems are rust, scaling, corrosion and so on.The main reason for these is that there is no good antifreeze.Good antifreeze not only has a low freezing point, but also has a variety of other functions to add ingredients, can inhibit foam, rust prevention, anti-electrolysis and anti-scale and so on, so it is still to remind the majority of the car mainly carefully choose the coolant beneficial to the water tank.

8. The cooling system is in bad condition

The most common failure of truck engine, such as live cylinder, explosion, cylinder punch leakage, serious noise, acceleration power drop, etc., are caused by abnormal working temperature of truck engine, excessive pressure, poor cooling system condition.Poor cooling system conditions will directly cause the engine to be unable to work at normal temperatures, resulting in the above serious failure.Cooling system maintenance of traditional way is to put the water in the tank, adding antifreeze and water only can, but then the cooling system has a lot of scale line is not clear, and the water pump, water jacket, the residual dirty can’t out of line, increase the water pump bearings, water pump impeller, pump water seal, the wear of the pump shell speed, reduce its life.Therefore, it is necessary to regularly use strong and efficient cleaning agent to clean the water tank and the rust and corrosion in the cooling system, and then add appropriate antifreeze and water purification.Only in this way can the engine work properly and the overall life of the tank and engine can be extended.
