List the 4 strokes in an internal combustion engine.

(b) Water cooled engine: In this type of engines, water is used for cooling the heated cylinder walls. (a) Air cooled engine:In this type of engines, the heated cylinder walls are cooled by continuous flow of air (e) V-engine: In this type of engines, combination of two inline engines equally set an angle. (d) Radial engine:In this type of engines, cylinders are arranged along the circumference of a circle. (c) Inline engine:In this type of engines, cylinders are arranged in line As it travels down the cylinder, the intake valve opens. The piston starts at Top Dead Center (TDC). One cycle is actually 2 complete rotations of the crankshaft. They are Intake, Compression, Power, and Exhaust. There are 4 strokes in an engine's cycle. (b) Horizontal engine:In this type of engines, cylinder is arranged in horizontal position. A single stroke in an engine refers to the piston traveling the full sweep of the cylinder. (a) Vertical engine:In this type of engines, the cylinder is arranged in a vertical position (b) Multi cylinder engine:This type of engines consists of 2, 3, 4, 6 or 8 cylinders (vi) According to the arrangement of cylinders (a) Single cylinder engine:This type of engines consists of only one cylinder. (c) Duel combustion engine: In this type of engines, combustion of fuel first takes place at constant volume and then at constant pressure (v) According to the number of cylinders (b) Diesel cycle engine:In this type of engines, combustion of fuel takes place at constant pressure

(a) Otto cycle engine: In this type of engines, combustion of fuel takes place at constant volume (iv) According to the cycle of combustion Engine): In this type of engines, the fuel gets ignited as it comes in contact with the hot compressed air. (a) Spark ignition engine (S.I.Engine):In this type of engines, fuel is ignited by an electric spark generated by a spark plug. (iii) According to the method of ignition
