Table 10.2 gives the comparison of SI and CI engines.   Table 10.2 Comparison of SI and CI engines

Table 10.1 shows a comparison of four-stroke and two-stroke engines.   Table 10.1 Comparison of two-stroke and four-stroke engines  

1 Four-stroke Spark-ignition Engine The details of various processes of a four-stroke spark-ignition engine with overhead valves are shown in Fig. 10.5. Within the four strokes, there are five events to be completed namely, suction, compression, combustion, expansion, and exhaust. Figure 10.5 Working principle of a four-stroke SI engine: (a) Suction stroke, (b) Compression stroke, (c) Expansion…

Figure 10.1 shows the classification of IC engines on the basis of cycle of operation into cylinder, type of fuel, method of supply of fuel, type of ignition, among others. Figure 10.1 IC engine classification

An engine may be defined as a device which converts one form of energy into mechanical energy. Mechanical energy can be further easily converted into electrical energy which is easier to transport and control. Heat engine is a cyclic device which transforms heat energy into mechanical energy. Heat engines are classified into the following: In…
