Normal operation of school bus is inseparable from the close cooperation of all components. In all parts, school bus engine can be said to be school bus heavyweights. If engine fails, then school bus is likely to "strike". Then how to do well on engine maintenance in our daily life.

1. Select appropriate oil. Diesel engines will have to use CB-CD grade of diesel engine oil according to mechanical load and a standard shall prevail of not lower than the manufacturer requirements.

2. Regularly replace the oil and filter. Any quality grade lubricating oil occurs in the course of nature will change. In order to avoid occurrence of failure, you should combine with a regular oil change conditions, and moderate oil (generally dipstick cap as well).

3. Keep a good crankcase ventilation of school bus. Now most of gasoline engine are equipped with PCV valve (crankcase enforced ventilation), but in the blow-by gas contaminants deposited around the PCV valve and valve may be clogged. Therefore, you must periodically remova contaminants around the PCV valve.

4. Regularly clean the crankcase. During operation of the engine, high-pressure combustion chamber unburned gas, acid, moisture, sulfur and nitrogen oxides through the gap between the piston ring and cylinder wall into the crankcase, mixed with powder metal parts produced by wear form sludge. Therefore, the crankcase should be cleaned regularly to keep the engine clean inside.

5. Regularly clean fuel system and control the generation of carbon deposition, enabling engine to maintain the best condition.

6. Tank engine rusts and fouls are the most common problems. Rust and scale will limit the coolant flow in the cooling system and reduce the cooling effect, causing the engine to overheat, and even cause engine damage. So regularly clean the tank and remove rust and fouling.

7. Maintenance three filter for school bus: refers to three filter air filter, oil filter and fuel filter. Three filter in the car engine for air, oil and fuel filter plays a role, and thus play a protective effect on the engine, but also improve the efficiency of the engine.
