Protect The Heart of The Car, Daily Maintenance Tips for The Engine After Commercial vehicle modific

Six tips for daily maintenance of the engine, the heart of the car. Since the engine is the "heart" of the car, what are the main ways to maintain the "heart" of the car? Commercial vehicle modification experts recommend the following six aspects.

1. Use lubricants of appropriate quality grade. For gasoline engines, SD-SF gasoline engine oil should be selected according to the additional devices and use conditions of the intake and exhaust system; for diesel engines, CB-CD diesel engine oil should be selected according to the mechanical load, and the selection standard shall not be lower than the requirements specified by the manufacturer.

2. Regularly replace the engine oil and filter elements. The oil quality of any quality grade of lubricant will change during use. To avoid failure, the engine oil should be replaced regularly in combination with the use situation, and the amount of engine oil should be moderate.

3. Keep the crankcase well ventilated. At present, most gasoline engines are equipped with PCV valves, but the pollutants in the blown air will be deposited around the PCV valves and may block the valves. Therefore, the pollution around the PCV valve must be removed regularly.

4. Clean the crankcase regularly. During the operation of the engine, high-pressure unburned 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 mix with the metal powder produced by the wear of parts to form sludge. Therefore, the crankcase should be cleaned regularly to keep the inside of the engine clean.

5. Clean the fuel system regularly to control the generation of carbon deposits to keep the engine in the best condition.

6. Rust and scale in the engine water tank are the most common problems. Rust and scale will restrict the flow of coolant in the cooling system, reduce heat dissipation, cause engine overheating, and even cause engine damage. Therefore, the water tank should be cleaned regularly to remove rust and scale.
