In the modern diesel engine, engine oil must perform four basic tasks without having a negative impact on engine performance and longevity of the engine. These functions of the oil are discussed here. Lubrication The engine oil provides a film of protection between the moving parts of the engine. This oil film reduces […]

Lubrication System
The lubrication system contains the following components: Oil pick-up tube and suction bell Oil pump Oil pressure relief valve Oil cooler bypass valve Oil cooler Oil filter bypass valve Oil filter Oil supply to turbocharger Oil supply to engine Oil Passages The lubrication system inside the engine includes the following components: Oil manifold (gallery) in […]
Air intake and Exhaust system
Inlet Manifold From the air cleaner (turbocharger/aftercooler, if equipped) the incoming air enters the inlet manifold. The inlet manifold directs the air into the cylinder head. Intake Stroke Air fills the inlet ports in the cylinder head. On the INTAKE stroke as the piston travels down in the cylinder the intake valves open, and air […]
Aftercoolers
Aftercoolers are used in conjunction with turbochargers in order to lower the temperature of the air coming from the turbocharger before the air enters the cylinders. This causes the air to be more dense, therefore contain more oxygen in a given volume. This increase in oxygen in the cylinders translates into greater power and efficiency […]
Precleaner
Many engines are also equipped with a precleaner. The precleaner is located before the inlet to the main air cleaner. The purpose of the precleaner is to collect much of the dirt before the air cleaner. This increases the service life of the air cleaner. The simplest type of precleaner is a simple mesh cap […]

Engine Performance Terminology
There are many factors that determine the performance of an engine. The operating conditions that an engine is exposed to and the specific application an engine is placed in can affect the performance of the engine. Many of the determining factors for performance, however, are determined by the manufacturer of the engine. Some of the […]
