Check Your Coolant – A coolant is a substance that mixes with water and protects the radiator from overheating or freezing. The power is then transmitted to the Crankshaft.ĥ Point Diesel Engine Maintenance Checklist:ġ. Piston – This diesel engine component compresses the air/fuel mixture then converts fuel energy into mechanical energy. Valve Guides – A cylindrical-shaped piece of metal that conducts heat from the combustion process by processing it out of the exhaust valve and into the cylinder head.Ħ. It does this by regulating the flow of air/fuel mixture inside the cylinder and by exhausting gas outside the cylinder.ĥ. Valves – These are located on the cylinder head and are responsible for the diesel engine’s smooth functioning. Cylinder Liners – A type of bore where an engine piston moves back and forth and is made of material strong enough to handle high heat and tremendous pressure.Ĥ. The design and construction of the bedplate must be stable and durable enough to provide support to the engine and the crankshaft.ģ. Bedplate – This is a metal plate that forms the foundation on which the diesel engine is built. Engine Block – The Engine Block is made of plates and castings which are welded both vertically and horizontally to increase strength and lend more support to the engine cylinder liners, crankshafts, and heads.Ģ. Here are the 6 main components of a diesel engine:ġ. The System – Creates the conditions for the proper functioning of the diesel engine – supplies air, removes exhaust, turbocharging, supplies and injects fuel, and lubrication and cooling.

The Running Parts – Functions to convert the power of combustion produced in the cylinders into keeping the engine running.ģ. The Structural Parts – The Structural Parts provides a protective casing for the Running Parts and functions to keep the components in place.Ģ. So what gives the Diesel Engine its power?Ī diesel engine is composed of 3 sections that allow it to function properly: the Structural Parts, the Running Parts, and the System.ġ. Diesel engines are also known for their ruggedness and durability.įor example, the diesel engines of Mercedes Benz hold the world record for logging 1.4 million kilometres without replacing the original engine.īecause it gives greater torque needed for hauling and pulling heavy objects, the most popular heavy-duty trucks use diesel engines.Ĭar manufacturers have also started to roll out Light-Duty trucks that are fitted with a diesel engine.
