What are the Basic Engine Components of a Vehicle

The first engine component of an engine which is dependent on the kind of engine and fuel used in an internal combustion engine is the ignition system. In the case of petrol engines, these are usually ignited by a precise and timed spark, while diesel engines by are ignited by compression heating.

In the case of a spark ignition engine, ignition is by a mixture of an electric spark from a spark plug, the timing of which should be controlled precisely. Note that almost all engines in gasoline are of this kind, while diesel engines timing is controlled in a precise manner by the injector and pressure pump.

Because of the heat generated by the air compression during the compression stroke, there is an ignition which would happen as the fuel and air mixture temperature has taken over the autoignition temperature. Note that the biggest number of compression ignition engines are those of diesels where the fuel is mixed with the air after reaching ignition temperature.

As there is a large area present of fuel to the oxygen in air, fuels would burn faster and more efficiently. In order to develop a fuel air mixture, there must be an atomization of liquid fuels, and to do this, the traditional method is by using a carburetor in petrol engines and with the diesel engines’ fuel injection. Fuel injection is also used by many modern petrol engines today although there is difference in the technology.

The simpler reciprocating engines are continuously using a carburetor in order for the cylinder to be supplied with fuel. Carburetor technology in vehicles have reached a level of very high sophistication and precision, but in mid 1980s, it lost out to fuel injection in terms of cost and flexibility. Small engines though still remain to use the simple forms of carburetor, like lawn mowers and the more sophisticated forms of engines used in small motorcycles.

Automobiles using larger gasoline engines have moved to using fuel injection systems. In the case of diesel engines, the use of fuel injection system has been done since the timing of the injection would start and control the combustion.

Where autogas engines is concern, it uses the system of fuel injection or the open or closed loop carburetors.

Several engines of internal combustion would now need a fuel pump. In order for the combustion chamber to be overcome, in the case of diesel engines, an all mechanical precision pump system is used and this would produce a timed injection directly into the chamber for combustion.

Among the parts of the engine that are the key parts of a four stroke engine are as follows, the crankshaft, connecting rod, one or more camshafts, and valves.
