The diesel engine was invented by Rudolf Diesel as an alternative to gasoline or petrol engines. Both of these engines function by creating an explosion in the closed piston chamber. The explosion occurred in the cylinder chamber due to fuel combustion. The only difference between these two engines is the cause of the explosion. The spark from the spark plug ignites the gasoline engine while in a diesel engine, the heat generated in the room causes the fuel to ignite.
Various Diesel Engine Parts
Cylinders: Similar to most other engines, diesel engines have multiple cylinders. Usually arranged in a ‘V’ or straight line. There is an alternative cylinder on both sides that are tilted to one side.
Piston head: Another important part of an engine includes the piston head which moves up and down through the perforated cavity in the cylinder.
Valves: There are two valves at the top of the engine which includes the intake valve and exhaust valve.
Fuel filter: Most of these engines use two types of fuel filters to ensure that the engine is free from clogging.
Incandescent spark plugs: These spark plugs are mainly used for heating the engine. This also prevents the formation of black soot in the engine.
Head Studs: For performance or heavy-duty applications, Head studs are preferred whenever possible over main cap bolts, in instances where options are available. Head studs provide the ability to obtain a much more accurate torque value because studs do not twist during tightening as bolts do. Because the mast remains stationary during nut tightening, it stretches in one axis only, providing a much more even and accurate clamping force.
Diesel engines are used in all types of vehicles including passenger cars, buses, trucks, and other vehicles. It is also used to drive motorboats and locomotive engines. It can be used in most agricultural equipment as well. It is widely used as a stand-alone power plant.
However, these machines differ from one another for many reasons. Some of these machines have two, four, or six cylinders. The cylinder capacity is different from each other. The cylinders used in automobiles are completely different from those used in motorboats. Some cylinders are in a straight line or arranged in a ‘V’.
In cars, trucks, and buses, these machines connect directly to the gearbox. But in big ships and locomotives, it drives propellers and motors by generating electricity.
Some Important Benefits
Most people prefer to use a diesel engine over a gasoline or gasoline engine because it is more efficient. Because it contains more heating value, it provides more efficiency than a gasoline engine for a given volume. It is also considered more reliable and efficient than gasoline engines due to the absence of a spark ignition system. This eliminates the possibility of blackouts even during humid climatic conditions.
The possibility of radio frequency emission is also eliminated due to the absence of coils, wires, and spark plugs. Radiofrequency emissions can often cause interference to communications and navigation equipment used in most aviation and marine applications.
With the increasing use of these machines, most of their spare parts are available in many online and offline stores at discounted prices.
