How long do diesel engines last?

The life of diesel engine is generally long. However, its service life will be lost after improper use. Therefore, it is necessary for us to know the consequences of improper operation and how to carry out routine maintenance.

How long do diesel engines last?

Generally, diesel engines can be used for four years under normal conditions. However, after misusing, diesel engines will have many faults, which will lead to the reduction of their service life. One of the main faults is the early wear of cylinder liner. The solution is as follows:

1. Proper maintenance of air filtration system. The failure of air filtration system of diesel engine will cause the wear of cylinder liner, which will greatly reduce the service life of cylinder liner. Therefore, there are higher requirements for air filtration, and multi-stage and efficient air filter should be selected.

2. Selection of quality and viscosity of diesel engine lubricating oil.

3. Control of engine temperature. The corrosion and wear of the cylinder liner of diesel engine depends on the working temperature of the diesel engine to a large extent.

4. Correct installation and use of cylinder liner, piston connecting rod group and crankshaft combination group.

5. Cavitation corrosion on cylinder liner outer surface and antifreeze coolant.

6. Reasonable selection of running in specifications. The new or overhauled diesel engine must be run in according to the operation manual before formal use. Generally, it can be put into full load operation after running in for 60 hours.

Do diesel engines last longer？

In the same level of exhaust volume vehicles, the service life of diesel engine is longer than that of gasoline engine.

1. Gasoline engine relies on the combustion of butane to produce explosive force, which has a continuous desalination effect on the lubricating oil of engine cylinder wall. Make the lubricating oil bottom slowly.

2. Diesel fuel contains a lot of light wax, although it is also burned in the cylinder, but it has little effect on the lubricating oil of the cylinder wall. It also has lubricating effect.

What happens if you put gasoline in a diesel engine?

Because of the high working pressure of diesel engine, the oil film strength on the friction pair surface is also required. However, the viscosity of gasoline oil is low, which can not meet the lubrication demand, and each friction pair will aggravate wear; in addition, the clearance between each part of diesel engine is relatively large, and the low viscosity gasoline oil can not seal the clearance of the cylinder wall well, and the gas flow in the crankcase will be larger and the engine power will be reduced; moreover, the engine power will be reduced; and It is the product of diesel engine combustion that has more corrosive substances. It will neutralize the detergent dispersant in gasoline oil quickly, and the oil will fail quickly. The connecting rod and crankshaft shells will wear or even peel off too early, and the service life of the engine will be greatly shortened.
