Automotive internal combustion engine control system

摘要

An automotive internal combustion engine control system drives auxiliary machinery by a starting motor while an internal combustion engine is at a standstill and efficiently regenerates energy by operating the starting motor as a power generator while the internal combustion engine is in operation. The output of the starting motor 5 capable of operating as a power generator is transmitted to an input/output pulley 10 mounted on the output shaft of the internal combustion engine 1 by an endless transmission belt 11 to start the internal combustion engine 1. The output of the engine is transmitted to auxiliary machinery 6, 7 and 8 by the endless transmission belt 11 while the internal combustion engine 1 is in operation. The output of the starting motor 5 is transmitted to the auxiliary machinery 6, 7 and 8 by the endless transmission belt 11 while the engine is in an intentional standstill. A speed-change mechanism 41 combined with the engine 1 transmits the rotation of the starting motor 5 at a high first gear ratio to the engine 1 to start the same, and transmits the rotation of the output shaft 2 of the engine 1 at a low second gear ratio to the starting motor 5 to make the starting motor 5 generate power while the engine 1 is in operation. The speed-change mechanism 41 is disposed so as to overlap the input/output pulley 10 at least partially with respect to an axial direction in which the output shaft 2 of the engine 1 extends. The input/output pulley 10 defines an oil chamber 39 for containing lubricating oil.
