History of internal combustion engine Necessity is the mother of invention. Though the internal combustion engine was discovered and developed before 19th century its use and improvements was intensified at around mid of the century when mining and refining of petroleum started1…

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. ...
