Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber. The … WebbThe cylinder has a piston that moves up and down for suction and compression. In different engines, cylinders are settled in different ways, such as a flat arrangement, a W-shape arrangement, a V-shape arrangement, and a horizontal or a single-row arrangement. 3) Connecting Rod.

Webb4-stroke engines have four valves so that pistons can go through four events to complete one 4-stroke cycle. A piston motion, either upward or downward, is defined as an event. After these four events, the cycle is complete and ready to restart. The intake and exhaust valves regulate the air/fuel mixture that enters and exits the cylinders. WebbThe piston moves down, not up, during the exhaust step. Compression happens before ignition, so it should be step 2.
