I am looking for supercharging of ic engine ppt

respect sir
i want super charging of ic engine ppt

please give me the ppt on negative pressure supercharger

An internal combustion engine works by drawing a mixture of air and fuel (the intake charge) into its cylinders, compressing that mixture, and then burning it. The more air/fuel mixture that can be crammed into the cylinders to burn, the more power the engine produces. You can increase power in three basic ways: you can improve the engine’s ability to draw more air and fuel into the cylinders and expel its burned exhaust gases (its volumetric efficiency, or ‘breathing’); you can increase the swept volume of the cylinders (the engine’s displacement) so you can fit more air and fuel into each cylinder; or you can pump the intake charge into the cylinders under high pressure, squeezing more air and fuel into the available volume.

Forcing air (or air-fuel mixture) through an engine’s intake valves at higher than atmospheric pressure is called supercharging. A supercharger, therefore, is a mechanical air compressor that pressurizes the air going into the engine’s intake manifold. There are several types of compressor used for car and truck engines, the most common being Roots-type, centrifugal, and Lysholm-type compressors; each has pros and cons, but they have the same basic purpose.

The output power of an internal combustion engine depends upon the amount of air utilized per unit time in the combustion process. Therefore, increasing the air consumption of an air in engine results in increasing the efficiency of an internal combustion engine. For this purpose, supercharging method is used.

The method of increasing the air capacity of an engine is called as supercharging and the device used to increase the density of air is called as supercharger. Supercharger is normally a blower or a compressor which increases pressure of density of air supplied to the engine. It gives more oxygen to engine to burn more fuel and do more work, hence increases the power.

A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power.Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine's crankshaft.When power is provided by a turbine powered by exhaust gas, a supercharger is known as a turbo supercharger– typically referred to simply as a turbocharger or just turbo. Common usage restricts the term supercharger to mechanically driven units.
