​How long can a marine engine last?

Marine engines have high thermal efficiency, good economy, good simplicity, and great adaptability to various types of ships, so they are used as ship propulsion power. Now marine engines are the main power of civil ships, small and medium ships, and conventional submarines. So how long can the marine engine last?

Use raw materials

Regardless of whether the modern marine engine uses diesel or gasoline, there are two ways to quickly run out of your fuel tank: one is water pollution, the other is the storage period is too long. When you store oil for up to 3 months without using it, the higher aromatics that provide octane and cetane combustion values begin to evaporate. When a quarter has passed, the gasoline with 87 octanes in the gasoline pump may become 80 with just enough burn value.

Repair marine engines

For marine engines, regularly check the oil level in the marine engine, regularly check the coolant status, and regularly check the fan belt. Check the seawater filter every 25 hours when the marine engine is on. Check the lubrication level of the marine engine nozzle and helm oil cup. The first time to replace the gasoline filter of a marine engine is 20 hours after start-up, and every 200 hours thereafter. Change the engine oil every 100 hours. Change gear oil every 200 hours. Replace the air filter every 200 hours. The fuel filter is replaced once a year. Keep marine engine oil clean, water clean, gas clean, and body clean. The use of lubricating oil with excellent detergency and dispersion properties and regular use of gasoline detergent to clean the intake valve and combustion chamber of the engine nozzle will help to extend the service life of the marine engine in a more orderly manner.

Parts replacement maintenance

The main parts and components of marine engines are procured globally from time to time, and the high configuration of the marine engine must be realized to ensure the normal operation of the ship. At the same time, the engine cooling system adopts an internal and external dual-circulation water cooling method. The internal circulation uses fresh water to cool the diesel engine, and the external circulation uses seawater to cool the fresh water through the sea and freshwater heat exchanger, which improves the continuity of the marine engine.

The durability of marine engines often depends on the degree of maintenance and use of marine engines. Therefore, we must use the marine engine correctly to extend its sustainability. If you want to know more, you can consult our company. 10 years focusing on diesel engines and genuine & OEM spare parts field fits for Cummins models.
