STOPPING DEVICE FOR INTERNAL COMBUSTION ENGINE, AUTOMATIC STOP AND START DEVICE FOR INTERNAL COMBUSTION ENGINE AND AUTOMOBILE EQUIPPED WITH SAME

摘要

PROBLEM TO BE SOLVED: To stop and retain a crank shaft at a rotation position making startability of an internal combustion engine good.;SOLUTION: A counterweight 40 attached to a crankshaft 38 has a projection 42, an electromagnet 44 attached to a crank casing 46 to align with the projection 42 when the crankshaft 38 reaches a rotational position of ensuring good startability of an engine 22. At a time of engine stop, electric power is supplied to the electromagnet 44 to attract the projection 42 of the counterweight 40 at a timing when the projection 42 of the counterweight 40 is practically aligned with the electromagnet 44, on the condition that the revolution speed of the crankshaft 38 is lowered to a revolution speed immediately before stop of rotation of the crankshaft 38, to stop rotation of the crankshaft 38 and retain the crankshaft 38 under that condition. At a time of engine start, electric power supply to the electromagnet 44 is removed and cranking is started. Consequently the engine 22 can quickly start.;COPYRIGHT: (C)2006,JPO&NCIPI
