1 Timely and regular replacement of engine filter element and engine oil Lubricating oil is very important to the engine and is the basis for engine operation. For different types and models of automobile engines, lubricating oils with matching grades and qualities should be used according to the design requirements of the engines. For example, for diesel engines, CB-CD grade diesel engine oil should be selected according to the mechanical load capacity, while SD-SF grade gasoline engine oil should be selected for the additional devices of the intake and exhaust system of gasoline engines, and the specific selection standards should not be lower than the requirements and specifications for engine production design.
2. Regularly clean the intake system of the engine. The intake system of the engine is divided into two parts: the intake duct and the filter element. Therefore, it is necessary to regularly clean the air inlet and the filter element to prevent the oil from leaving more residual impurities when passing through the pores of the filter, which will cause the filter to block. The cleaning of the air filter element depends on the driving air environment. The cleaning method is to use high-pressure gas to blow out the impurities in it from the inside to the outside.
3 Keep the crankcase well ventilated Now most gasoline engines are equipped with PCV valve (crankcase forced ventilation device) to enhance the ventilation function of the engine, but the unclean pollutants in the blow-by gas will still settle around the PCV valve, which is easy to Cause PCV valve blockage. If the PCV valve is blocked, the polluted gas will flow into the air filter reversely, thereby polluting the filter element and reducing the filter capacity of the engine. If the dirty mixture is inhaled, the crankcase will be polluted, which will increase fuel consumption, aggravate engine wear, and seriously cause engine damage. Therefore, the pollutants around the PCV valve should be removed in time and regularly.
4. Regularly clean the crankcase to keep the inside of the engine clean. When the engine is running, the high pressure in the combustion chamber has incomplete combustion gas, water, sulfur, acid and nitrogen oxides, which enter from the gap between the piston ring and the cylinder wall. The crankcase, and some metal powder produced by wear and tear on its parts cause the cylinder to scuff. Therefore, it is necessary to regularly use a professional cleaning agent to clean the crankcase to keep the inside of the engine clean.
5. Regularly clean the fuel system to keep the engine in the best condition. During the combustion process of the fuel in the combustion chamber, carbon deposits and colloids are easily formed, which are deposited in the oil passage, fuel injection nozzle, carburetor and combustion chamber, which interferes with the flow of fuel. The normal air-fuel ratio is destroyed, resulting in poor fuel atomization, which causes problems such as engine knocking, panting, poor acceleration, and unstable idle speed. Therefore, regular use of professional cleaning agents to clean the carbon deposits deposited in the fuel system can keep the engine running at its best.
6 Carry out regular maintenance on the water tank Scaling and rusting of the engine water tank are the most common problems. Scale and rust will hinder the flow of coolant in the cooling system, reduce its heat dissipation effect, cause the engine to overheat, and in severe cases, cause engine damage. When the coolant is oxidized, it will also generate acidic substances, which will corrode the metal parts of the water tank, causing damage to the water tank and leakage. Therefore, it is necessary to regularly use a strong and efficient water tank cleaning agent to clean the water tank to remove scale and rust in the water tank. This will not only keep the engine working normally, but also prolong the overall life of the engine and water tank.
