Abstract

The invention relates to an engine energy transmission system, discloses a magnetic drive engine energy transmission system and belongs to the field of resources and power. The magnetic drive engine energy transmission system comprises an engine and a crankshaft flywheel unit. The engine comprises a fuel injector, a cylinder cover, a radiating sheet, a scavenging port, an intake port, an exhaust port and a piston. The crankshaft flywheel unit comprises a crankshaft, a flywheel, a flywheel gear ring, and a flywheel permanent magnet set. Under the mutual magnetic action of piston and flywheel permanent magnets in an engine cylinder, during the process of acting and exhausting, reciprocating motion of the piston is converted into rotational motion of the crankshaft, and acting force of the piston is converted into torque that the crankshaft outputs, and automobile wheels are driven to rotate; during the process of compressing and intake, rotational motion of the crankshaft is converted into reciprocating linear motion of the piston. The magnetic drive engine energy transmission system has the advantages that the complexity of engine energy transmission chain structure can be decreased, engine size is reduced and the engine system energy efficiency is improved.

Description

technical field [0001] The invention relates to an engine energy transmission system, in particular to an engine energy transmission system based on magnetic drive, and belongs to the field of energy and power. Background technique [0002] Traditional engines include two types of thermal cycles, two-stroke and four-stroke. Since the linear motion of the piston cannot directly realize the rotational power output, it is necessary to rely on the crank-link mechanism to complete energy conversion, transmit force and change the motion mode. When the four-stroke engine is working, the crank-link mechanism converts the reciprocating motion of the piston into the rotational motion of the crankshaft during the working stroke, and at the same time converts the force on the piston into the torque output by the crankshaft to drive the wheels of the car to rotate. In the other three strokes, namely the intake, compression, and exhaust strokes, the rotational motion of the crankshaft is ...
