The working principle of a two-stroke generator: There are three holes in the cylinder block of the engine, namely the intake hole, the exhaust hole and the ventilation hole. These three holes are closed by the piston at a certain time. Its work cycle consists of two strokes:
1. First stroke: The piston moves upward from bottom dead center. After the three air holes are closed at the same time, the mixed gas entering the cylinder is compressed. ; When the combustible mixture flows into the crankcase.
2. Second stroke: When the piston is compressed near top dead center, the spark plug ignites the combustible mixture and the expansion of the gas pushes the piston down to do the work. At this time, the air intake hole is closed and the combustible mixture sealed in the crankcase is compressed; When the piston approaches bottom dead center, the exhaust hole opens and the exhaust gas flows out.catch, then the ventilation hole opens; the pre-pressed combustible mixture rushes into it. The cylinder removes the exhaust gases and carries out the ventilation process.
