Find out how a car's oil affects diesel engine efficiency
A car's oil plays a vital role in the efficient operation of an engine. Apart from simply lubricating, it contributes significantly to its durability, so understanding how oil can affect a diesel engine is essential for its maintenance and also to prevent potential problems in the long term.
Here are some of the functions of diesel engine oil:
1. Effective lubrication:
The main purpose of oil in a diesel engine is to provide effective lubrication by reducing friction, preventing premature wear, and ensuring smooth and efficient performance.
2. Protection from pollution:
These types of engines tend to operate in more severe conditions than gasoline engines, so the oil plays a crucial role in capturing and containing pollutants. This prevents the accumulation of sediment in the engine, improving its efficiency and, of course, prolonging its useful life.
3. Thermal stability:
Diesel car engines generate higher temperatures than gasoline engines. The oil must be able to withstand these extreme temperatures without decomposing or losing its lubricating properties. This is why oils designed for diesel engines tend to have greater thermal stability.
4. Viscosity maintenance:
Oil viscosity is essential to ensure proper lubrication in differing temperature conditions. In cold climates, an oil that maintains its viscosity helps facilitate starting the engine, and in warmer climates, it prevents the oil from losing its lubricating properties.
5. Reduced fuel consumption:
A high-quality oil contributes to fuel efficiency by reducing internal engine friction. Less friction means lower fuel consumption and higher efficiency.
6. Control of the formation of deposits:
Some oils are formulated with additives that help control the formation of deposits in diesel engines. These deposits can negatively affect efficiency by blocking ducts and reducing air and fuel flow.
7. Control of engine sealing:
Using a suitable lubricant contributes to engine sealing and prevents combustion chamber gases from escaping into the crankcase, which causes reduced engine performance and increased oil consumption.
