Marine diesel engine parts manufacturers explain the maintenance knowledge of marine diesel engines

The basic composition of marine diesel engine: (1) Main fixing parts: frame, base, cylinder and cylinder head. (2) Main moving parts: piston, connecting rod assembly, crankshaft. (3) Air distribution mechanism and ventilation system. (4) Fuel system. (5) Lubrication system. (6) Cooling system. (7) Start and control system.

After the new diesel generator or the sealed generator has been run-in (the first 50 hours), the following maintenance work is required:

1. Clean or replace the air filter

2. Replace the engine lubricating oil

3. Replace or clean the filter element of the lubricating oil filter

4. Re-tighten the bolts and screw caps of each part

In the maintenance of marine diesel engine, the new diesel generator should try to avoid sudden increase in load or high-speed operation, and do not mix different brands of lubricating oil, otherwise it will easily lead to abnormal wear of moving parts. When filling fuel into the fuel tank, there should be a filter at the fuel filling port, and it is better to put a filter cloth; the fuel should be left in the fuel tank for more than 24 hours to allow water and impurities to settle before use; L28/32 diesel engine parts should be used frequently Open the drain plug of the daily fuel tank to drain the water and sediment at the bottom.
