Know Some Common Engine Components in Your Unit

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. Diesel engines are ignited by compression heating while petrol engines are usually ignited by a spark that is precisely timed.

With a controlled and precise of a mixture of an electric spark from a spark plug, the mixture would create an ignition in a spark ignition engine. While this is the ignition type for almost all gasoline engines, the timing on the other hand for diesel engines is through a precise and controlled pressure pump and injector.

Ignition happens when the temperature of the fuel/air mixture is taken over by the autoignition temperature because there is heat generated during the compression stroke of which air is compressed. 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.

In order to supply fuel into the cylinder, the use of carburetor is used in simpler reciprocating engines. From the mid 1980s, carburetor technology in cars have attained a very high degree of precision and sophistication, but lost out on the cost and flexibility to fuel injection. Small engines like lawn mowers and small motorcycles in their more sophisticated forms, remain to use the simple forms of carburetor.

Automobiles using larger gasoline engines have moved to using fuel injection systems. The system of fuel injection has been always used in diesel engines and this is because the timing of the injection would kick off and controls the combustion.

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

Several engines of internal combustion would now need a fuel pump. As for diesel engines, an all mechanical precision pump system is used which delivers a timed injection into the combustion chamber, and thus, in order to overcome the pressure of the combustion chamber, there should be a time injection directed into the combustion chamber.

In the case of a four stroke engine, there are key parts that form the parts of the engine, and these are the crankshaft, connecting rod, one or more camshafts, and valves.
