The engines main functionis to convert air and fuel into rotary motion so it can drivethe wheels of the car. How does it do that ??…. Well let’sstart with a cutaway of the engine and see all the major partsthen we will get into the actual mechanics. Pistons: Most commonengines have , , or pistons, which move up and down in thecylinders. On the upper side of the piston is what is called thecombustion chamber where the fuel and air mix before…

What is a -stroke diesel engine?As the name suggests, these engines work on reciprocatingactions of pistons. One stroke means one linear motion of thepiston in one direction. When the piston moves in the oppositedirection, that is counted as another stroke.For a -stroke engine, the piston has to move up, and then downto complete one cycle of the engine. In those strokes of thepiston, the crankshaft will have turned revolution.The strokes of the piston is to complete stages of thecombustion cycle – air intake, compression, combustion andexhaust. As you might have known, in order for a fire orexplosion to occur…
