subject: Overview Of Various Diesel Engine Parts [print this page] The Diesel Engine was invented by Rudolf Diesel. It was invented as an alternative to the petrol engine. The difference between the Diesel Engine and Petrol Engine is the nature in which the combustion is begun. Combustion in the Diesel Engine begins by the heat of compression, while the petrol engine begins combustion by a spark plug. Thus, the Diesel Engine does not have the problems of ignition during cold or damp weathers.
Diesel Engines have come a long way since their prototypes. The modern Diesel Engine has been designed for increased efficiency. Some of the Diesel Engine Parts are:
Cylinder Block (Cy. Block): The Cylinder Block is used to accommodate the cylinder liner. It also bears the movements of the piston. Lubrication oil is also carried to the components of the Diesel Engine through drilled passages. Cast iron is usually used to manufacture diesel engines. The use of cast iron ensures that there is lesser wear and tear and better efficiency in the functioning of the machine.
Cylinder Head (Cy. Head): The Cylinder Head is placed above the cylinder block. They allow the air and fuel to be fed into the cylinder. The spark plugs, fuel injectors and the valves are also mounted on the head. Cylinder Heads thus perform the function of the seal and exhaust valves. The number of cylinder heads will depend on the type of engine.
Crankshaft: The Crankshaft is used to change the reciprocating movements of the pistons into circular motions. It rides on bearings which are specially designed to support the movements. Forged Steel is used to make Crankshafts.
Crankcase: The crankcase holds the oil pan at its bottom. The lubricating oil is stored in the oil pan. Larger diesel engines often have several smaller pans.
Pistons: The pistons convert the energy of the gases into mechanical energy. It is a very important part of the engine. Cast iron alloys or aluminum is usually used to make Pistons. A lot of aspects of the engine, like the power and the mileage, depend on the Pistons.
Though the parts of a diesel engine are easily available in the market, it is important to ensure that only quality spare parts are used. Spurious parts result in the reduction of efficiency and often lead to other major problems. Parts made by prominent manufactures go a long way in ensuring an efficient and trouble-free performance.
