History of Internal Combustion Engine - Literature review Example

Resonance intake manifold The structure of the internal combustion engine requires a particular length of the manifold. The ability and the efficiency of an internal combustion engine will be determined by the size of the manifold. Short manifolds reduce the performance of the engine. Consequently, manufacturers have developed a system that allows for the length of the manifold to be controlled. Because a vacuum is created when the air is forced out by the piston, the fuel in form of vapour enters and creates energy.

The valve that allows the fuel in closes and adds pressure to the fuel. When the fuel mixture is accelerated oscillations are developed depending on the length of the manifold. When the length of the manifold varies, it is also possible to vary the oscillations. Variability in length of the manifold usually affects the power, the speed of the operation and efficiency in fuel use. To maximize the efficiency of this system two intakes are refashioned each of which is regulated by a valve connected to two manifolds.

A short manifold usually functions when the engine is fully loaded while the long one operates when the engine is not fully loaded. . This spin usually assists in distributing the fuel (in form of vapor) and makes the air and fuel vapor to uniformly mix. With this mixture the process of combustion is enhanced, completed and can even to an extent prevent the engine from knocking. When few revolutions per minute are recorded the velocity of the air is enhanced, while with more revolutions increases per minute, most paths are opened thereby increasing the load.

A high volume of air therefore generally leads to increase in the power of the engine3. Vacuum boost theory The difference in pressure between the inlet manifold and the outside atmosphere is referred to as manifold vacuum. Therefore it acts as a measure of the amount of the airflow which is restricted in the engine. The amount of power the engine generates has a relationship with the amount of air that enters the internal combustion engine. For engines that use diesel in the internal combustion engine, greater dependence lies on the amount of fuel that is supplied while those using gasoline will depend on the restrictions of the airflow.

Manifold vacuum is usually in all the engines that use natural fuel as source of energy. The engine’s geometry and the speed of rotation affect the input flow in the engine, because geometry cannot be adjusted while the engine has commenced to run. The input flow in the intake manifold should not be restricted as this will interfere with the power of the engine and the possibilities of the engine breaking down. When the air from the atmosphere is allowed in the engine there is possibility that the pressure will automatic increase thereby creating the vacuum.

The engine is now powered. We can conclude that engines running on natural fuel such as diesel generate
