2) stable operation process; When stable operation process starts, piston (4) is positioned at top dead center, flywheel outer rim S utmost point flywheel permanent magnet (13) starting point is through flywheel (10) top, oil sprayer (1) sprays into after the oil inflame of cylinder interior, the gas pressure producing promotes piston (4) and moves downward, externally acting, flywheel (10) is subject to piston permanent magnet (13) active force along clockwise direction, continues to turn clockwise; In the time that relief opening (7) is opened, motor starts free exhaust, after scavenging port (5) is opened, starts scavenging stroke; When piston 4) while moving to lower dead center downwards, flywheel outer rim N utmost point flywheel permanent magnet (12) starting point is through flywheel (10) top, after this, piston (4) starts to be subject to N utmost point flywheel permanent magnet (12) active force upwards, and move upward under this power effect, complete compression and intake stroke, in the time of flywheel outer rim S utmost point flywheel permanent magnet (13) starting point process flywheel (10) top, piston (4) moves to top dead center, oil sprayer (1) sprays into the oil inflame of cylinder interior, repeats above-mentioned to-and-fro motion;
Magnetic interaction between piston permanent magnet (8) and flywheel permanent magnet in cylinder, in motor acting and exhaust stroke, the to-and-fro motion of piston (4) is transformed into rotatablely moving of bent axle (11), change the active force on piston (4) into bent axle (11) the externally torque of output, to drive automotive wheel to rotate; In compression and intake stroke, again rotatablely moving of bent axle (11) is transformed into the linear reciprocating motion of piston (4);
3) restart procedure that catches fire; While making to catch fire in cylinder due to reasons such as combustion fluctuations, under the effect of piston (4) permanent magnet magnetic force on flywheel, move downward, until flywheel (10) outer rim N utmost point flywheel permanent magnet (12) starting point process flywheel top, now piston (4) moves to lower dead center; This back piston (4) starts to be subject to S utmost point flywheel permanent magnet (13) active force upwards on flywheel, under this power effect, moves upward; In the time that the starting point of flywheel outer rim S utmost point flywheel permanent magnet (13) passes through flywheel (10) top, piston (4) moves to top dead center; In this process, in cylinder, air is compressed, and the oil sprayer (1) on cylinder cap ejects high pressure fuel, and burning produces high-pressure gas, promotes piston (4) to lower dead center operation, starts externally acting, and motor enters stable operation stage again.
5. a kind of magnetic drives engine power delivery system according to claim 1 and 2, is characterized in that: the flywheel permanent magnet quantity comprising by the flywheel set of permanent magnets changing on flywheel (10) or change number of cylinders change motor into free-piston (4) four stroke engine; Meanwhile, because free-piston (4) motor has alterable compression ratio characteristic, therefore described motor both can be using gasoline as fuel, also can be using the multiple fuels such as diesel oil or inflammable gas as fuel.
6. a kind of magnetic drives engine power delivery system according to claim 1 and 2, is characterized in that: described motor is selected two-stroke engine with double cylinders structure, mainly comprises motor and crankshaft-flywheel assembly; Described motor quantity is two, and crankshaft-flywheel component count is one, and two motors are arranged symmetrically in crankshaft-flywheel assembly both sides; Meanwhile, because free-piston (4) motor has alterable compression ratio characteristic, therefore described motor both can be using gasoline as fuel, also can be using the multiple fuels such as diesel oil or inflammable gas as fuel.
7. a kind of magnetic drives engine power delivery system according to claim 1 and 2, is characterized in that: described a kind of magnetic drives engine power delivery system can be moved as single cylinder engine, or moves as multi cylinder multimode.
8. a kind of magnetic drives engine power delivery system according to claim 3, is characterized in that: described a kind of magnetic drives engine power delivery system can be moved as single cylinder engine, or moves as multi cylinder multimode.
