![]() It is also assumed that the ideal indicator diagram is strictly followed. The air is simply heated and cooled to undergo a cycle. engine does not undergo a cyclic change but it is assumed here that the working medium is pure air which does not undergo any chemical change. The petrol engines operate on this cycle.Īn I.C. The engines operating on this cycle are known as Otto-cycle engines. This cycle was introduced in practical form by a German scientist Otto, in 1876, although it was described by French scientist Beaude Roches in 1862. Classification by Cycle of OperationsĪccording to the cycle of operations, the automobile engines may be of the following three types: The fuel is injected in the burner where it burns and further raises the pressure. As the rotor rotates, the air between the blades is carried around and thrown out by centrifugal force into the burner. The gasifier consists of a compressor which has a rotor with a series of blades around its outer edge. The power turbine then turns the vehicle wheels through a series of gears. The gasifier section burns fuel in a burner and delivers the resulting gas to the power section, where it spins the power turbine. The fuel used in a gas turbine can be gasoline, kerosene, or oil. The correct air-petrol mixture is obtained from the carburettor.Ī gas turbine essentially consists of two sections-a gasifier section and a power section. Air-petrol mixture is sucked into the cylinder during the suction stroke of the piston. Petrol or gasoline is a hydrocarbon, made up of hydrogen and carbon compounds. The petrol engine uses petrol for its running. Classification by Types of Fuel usedĪccording to the type of fuel used the engines are classified into three categories Read also: List of Car Engine Parts: Its Function (With Pictures) 1. Several other types of internal combustion engines are also being proposed for use as automotive power plants. In addition to the above classifications, the internal combustion engines are classified on the following bases also : Types of Engineįollowing are the different types of engine: The heat energy is converted into mechanical energy by the expansion of the gases against the piston attached to the crankshaft that can rotate. In internal combustion engines, the chemical energy stored in their operation. The energy developed during the combustion of fuel is transmitted to steam which acts on the piston inside the cylinder. On the other side, external combustion engines are those heat engines that burn their fuel outside of the engine cylinder. Heat engines like internal combustion engines burn their fuel inside the engine cylinder. ![]() Classification by Type of CoolingĪn engine is a machine designed to convert one form of energy into mechanical energy.
