Moving Parts:
1. Piston: The piston moves up and down within the cylinder to create the necessary compression and expansion for combustion.
2. Connecting Rod: The connecting rod connects the piston to the crankshaft, converting the linear motion of the piston into rotational motion.
3. Crankshaft: The crankshaft is the main rotating component of the engine and is responsible for converting the reciprocating motion of the piston into rotary motion.
Four-Stroke Engine:
Moving Parts:
1. Piston: Similar to the two-stroke engine, the piston moves up and down within the cylinder, but in this case, it completes four strokes: intake, compression, power, and exhaust.
2. Connecting Rod: The connecting rod connects the piston to the crankshaft, just like in the two-stroke engine.
3. Crankshaft: The crankshaft in a four-stroke engine is similar to that of a two-stroke engine, but its design and operation differ due to the additional strokes required for complete combustion.
4. Camshaft: The camshaft is an additional moving part in the four-stroke engine. It controls the timing of the valves by opening and closing them at specific intervals during the engine cycle.
5. Valves: Valves are essential in a four-stroke engine. They control the flow of air and fuel into the cylinder (intake valve) and the exhaust gases out of the cylinder (exhaust valve).
In summary, the main difference between the moving parts of a two-stroke engine and a four-stroke engine lies in the additional components required in the four-stroke engine to facilitate the complete combustion cycle, including the camshaft and valves. This difference accounts for the distinct operational characteristics and efficiency of each engine type.
