Webb19 maj 2024 · As the piston pushes itself up into the cylinder, the fuel air mixture that is sealed in there gets compressed, then a spark plug makes the whole thing blow up. Rather than looking like a scene from Star Wars, this explosion is contained inside the engine, and serves only to push the piston back down quickly and powerfully. small roblox torsoWebbDuring the expansion or power stroke, the high-pressure combustion gases expand moving the piston down and delivering the power. The gases expand completely, the exhaust valve opens, and the gases are expelled out during the exhaust stroke. The fuel and air are atomized and premixed in a carburetor. small robins for craft ebay

"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.
