Title: Starting device for engine
Inventor: OHARA YASUSHI
IPC: F02D45/00
Filed: 2001-07-09
Abstract: PROBLEM TO BE SOLVED: To improve starting performance of an engine without increasing output of a starting motor connected to a crank shaft. SOLUTION: When the engine stops, a crank angle is set in an angle region at a delayed angle side compared to the crank angle by which an intake valve of the engine is closed, and compressed air in a cylinder is leaked until the next starting so that a peak value of the pressure in the cylinder is lowered. The crank shaft may be set in an angle region wherein the crank shaft can be accelerated so that the rotational speed of the crank shaft at the crank angle whereby rotational load of the motor reaches the peak value in the first place after starting of cranking can be a rotational speed whereby a shortage of the output torque of the motor with respect to the peak value can be compensated by inertia of a rotating part including the crank shaft. Thus, the crank shaft is fully accelerated before the rotational load reaches the peak value (Steps S101 to S103). Accordingly, the engine can be surely started even by a motor of low torque.
