To know the normal operation of all vehicles can not be separated from the close cooperation of various components, kindergarten school bus is not out. In these parts, the
school bus engine is among the most important. If the engine fails, then the school bus is likely to "strike", all of our daily life to do the maintenance of the engine, then how to do the maintenance of the engine?

1. Select the appropriate oil

General diesel engine will have to choose according to mechanical load CB-CD grade diesel engine oil, selection criteria to not less than the manufacturer requirements.

2. Specified time to replace the oil and filter

Any quality of the oil in the course of the oil quality will change, in order to avoid failure, should be combined with the conditions of regular oil change, and make the amount of oil is moderate (generally the upper limit of the oil scale as well).

3. Ensure that the crankcase is well ventilated

Most petrol engines are now equipped with PCV valves (crankcase forced ventilation), but the pollutants in the blow-by gas will be deposited around the PCV valve, which may clog
the valve. Therefore, periodically remove contaminants from the PCV valve.

4. Clean the crankcase frequently

During the operation of the engine, the high pressure unburned gas, acid, water, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the clearance
between the piston ring and the cylinder wall and mix with the metal powder produced by the wear of the parts, Sludge. Therefore, the crankcase should be cleaned regularly to
keep the inside of the engine clean.

5. Always clean the fuel system

Often cleaning the fuel system, control the formation of carbon deposition, can make the engine to maintain the best condition.

6. Engine tank rust and scaling problems

Rust and scale can limit the flow of coolant in the cooling system, reducing heat dissipation, resulting in engine overheating, and even damage to the engine. So always clean the water tank, remove one of the rust and scale.

7. Maintenance of three filters

The so-called three filter is the air filter, oil filter and gasoline filter. Three filters in the school bus car engine on the air, oil and gasoline play a filtering effect, which plays a protective effect on the engine, but also improve the efficiency of the engine.
