Diesel engines have the notoriety of being durable beasts that last longer than your standard gas engine. However, these engines don’t have eternal life and do have a breaking point if the factors that affect the life expectancy of a diesel engine are taking their toll.

Cylinder Liners

Current methods for assessing diesel engine longevity consider attrition on cylinder liners in domestic and international engines. When the cylinder liners in a diesel engine wear unevenly, the gap between the piston ring and the cylinder wall widens, which causes a great deal of air to leak out of the cylinder body over time.

This is the primary cause of diesel engines failing. Cylinder pressure, however, may directly relate to the wear of the cylinder liner. Meanwhile, assessing the state parameters of cylinder pressure in a diesel engine requires disconnecting the injector’s direct connection to the relevant sensor.

Fuel Injection

Low injection pressure leads to poor fuel atomization quality, resulting in poor fuel-to-air mixture and diminished diesel engine performance. Therefore, the oil pressure should be sufficiently high to enable the dependable transfer of oil to the lubrication surface, and the height of the injection pressure will become an essential factor in the life of the diesel engine.

Oil pressure is important because if it’s too low, the engine won’t get enough lubrication to prevent wear on the piston rings, cylinder walls, and crankshaft bearings, decreasing the engine’s dynamic performance and shortening its lifespan.

External Environment

Other environmental elements and circumstances can affect a diesel engine’s life. Three external variables affect parts' wear and tear. The first category includes elements independent of drivers. Second, there is a connection between the variables of vehicle users, such as the road, weather, and the items’ kinds, quantities, and distances. The third group includes aspects like the driver’s technological proficiency and the vehicle’s upkeep.

Because these characteristics may change significantly depending on the local environment, it is hard to measure them accurately.
