1. use the appropriate quality grade of lubricating oil
The gasoline engine should choose SD--SF grade gasoline engine oil according to the additional equipment and use conditions of the intake and exhaust system; the diesel engine should choose CB--CD grade diesel engine oil according to the mechanical load, and the standard is not less than the manufacturer's requirements.
2. regular replacement of oil and filter core
any quality grade lubricant will change during its use. After a certain mileage, the deterioration of performance will bring various problems to the engine. In order to avoid failures, we should regularly change the oil with the conditions of use, and make the oil volume moderate (generally the upper limit of the oil gauge is good). When the oil passes through the pores of the filter, the solid particles and viscous substances in the oil will accumulate in the filter. If the filter is blocked, the oil can not pass through the filter core, it will dilate the filter core or open the safety valve, through the bypass valve, it still brings the dirt back to the lubricating part, so that the engine is worn and the internal pollution is aggravated.
well ventilated.3. crankcase
Now most of the gasoline engines are equipped with PCV valves (crankcase forced ventilation) to drive the engine to air, but the contaminant in the gas is “ it will be deposited around the PCV valve, and the valve may be blocked. If the PCV valve is blocked, the polluted gas is reverse flow to the air filter, pollutes the filter core, reduces the filtration capacity, and the inhaled mixture is dirty, causing the pollution of the crankcase, which leads to the increase of fuel consumption, the increase of the engine wear and even the damage to the engine. Therefore, PCV must be regularly maintained to remove pollutants around the PCV valve.
4. regularly cleaning crankcase
During the operation of the engine, the high pressure uncombustible gas, acid, water, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, and mixed with the metal powder produced by the wear and tear of the parts to form the oil sludge. When the quantity is small, when it is suspended in the oil and the volume is large, it will precipitate from the oil and block the filter and oil hole, which will cause the engine lubrication difficult and cause attrition. In addition, the oil in the high temperature oxidation will produce paint film and carbon deposition on the piston, making the engine oil consumption, power decline, serious when the piston ring to die and pull the cylinder. Therefore, regularly use BGl05 (lubricating system efficient and quick cleaning agent) to clean the crankcase and keep the engine clean inside.
5. regular cleaning of fuel system
In the process of burning fuel through the oil road to the combustor, fuel will inevitably form a colloid and carbon deposit, deposit in the oil channel, carburetor, nozzle and combustion chamber, interfere with the flow of fuel, destroy the normal air fuel ratio, make the fuel atomization bad, cause the engine to shake, blast, idle the idle speed instability, and accelerate the bad speed. And other performance problems. Use BG208 (fuel system strong and efficient cleaning agent) to clean the fuel system and regularly use BG202 to control the production of carbon, which can always keep the engine in the best state.
6. regular maintenance water tank
rust and scaling are the most common problems. Rust and scale will limit the flow of coolant in cooling system, reduce heat dissipation, cause engine overheating and even cause engine damage. The oxidation of coolant will also form acidic substances, which will corrode the metal parts of the water tank, resulting in water tank breakage and leakage. Regular use of BG540 (water tank strong and efficient cleaning agent) cleaning water tank to remove rust and scale, not only to ensure the normal operation of the engine, but also to extend the overall life of the tank and engine.
