1 use of appropriate quality level of lubricating oil. The gasoline engine should be based on the intake and exhaust system of the additional device and the use of the conditions of choice of SD-SF grade gasoline engine oil, diesel engine according to the mechanical load of the choice of C
B-CD grade diesel engine oil, the selection criteria to not less than the requirements of manufacturers.
2 regular replacement of oil and filter element. Any quality grade of lubricating oil in use in the process of oil will change, in order to avoid the fault should be in combination with conditions of oil on a regular basis, and a moderate amount of oil (usually in oil rod cap as well).
3 maintain good ventilation. Now most of the gasoline engine is equipped with PCV valve (crankshaft box forced ventilation device), but the gas in the gas will be deposited in the PCV valve around the valve, the valve can be blocked. Therefore, it is required to regularly clean up the pollutants around the PCV valve.
4 regular cleaning of crankcase. Engine in operation process, combustion chamber pressure unburned gas, acid, water, sulfur and nitrogen oxide by the gap between piston ring and cylinder wall into the crankcase in, and parts wear of metal powder mixed together, to form sludge. Therefore, it is time to clean the crankcase and keep the engine clean.
5 regular cleaning of the fuel system, generating control of coke, so the engine can maintain the best condition.
6 engine water tank rust, scaling is the most common problem. Rust and scale will restrict the flow of coolant in the cooling system, reduce the cooling effect, causing the engine to overheat, or even cause damage to the engine. So to regular cleaning tank, remove rust and scale.
7 maintenance: refers to the filter filter air filter, oil filter and gas filter. Filter in the automobile engine of air, oil and gasoline plays a filtering effect, thus protecting the engine, but also improve the work efficiency of the engine.
