Engine basic structure
An engine is a complex machine composed of many mechanisms and systems. Whether it is a gasoline engine or a diesel engine; whether it is a four-stroke engine or a two-stroke engine; whether it is a single-cylinder engine or a multi-cylinder engine. In order to complete the energy conversion, realize the work cycle, and ensure long-term continuous and normal work, the following mechanisms and systems must be provided.
(1) Crank connecting rod mechanism
The crank connecting rod mechanism is the main moving part for the engine to realize the working cycle and complete the energy conversion. It consists of a body group, a piston connecting rod group and a crankshaft flywheel group. During the power stroke, the piston moves linearly in the cylinder under the gas pressure, converts it into the rotational motion of the crankshaft through the connecting rod, and outputs power from the crankshaft. During the intake, compression and exhaust strokes, the flywheel releases energy and converts the rotational motion of the crankshaft into linear motion of the piston.
