Abstract

The purpose of this invention is to detect reverse rotation of an engine based on output signals of a rotor sensor, and prohibit fuel injection or engine ignition when the engine is rotated reversely. In this engine start control device, a crankshaft is reversely rotated up to a prescribed position after engine stop to be ready for next engine start. It is provided with an injector to inject fuel as the crankshaft reaches a prescribed angle, an ignition device to ignite the engine at a prescribed timing after fuel injection, an ACG starter to function as a starter motor and a generator, the rotor sensor to output phase signals for multiple phases by detecting the rotor position of the ACG starter, a means to determine the rotation direction of the engine based on the output signal of the rotor sensor, and a means to prohibit fuel injection when the engine is reversely rotated.

Description

technical field [0001] The present invention relates to an engine start control device, and more particularly to an engine start control device that reverses a crankshaft to a predetermined position after an engine stop, and improves startability by starting from the reverse position when the engine is started. Background technique [0002] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 10-148142 [0003] [Patent Document 2] Japanese Unexamined Patent Publication No. 6-64451 [0004] [Patent Document 3] Japanese Unexamined Patent Publication No. 7-71350 [0005] Conventionally, a starter motor and a generator for an internal combustion engine are mounted independently, but Patent Document 1 discloses a multi-phase AC starter-generator device (ACG starter) in which their respective functions are integrated. [0006] On the other hand, when the internal combustion engine is started, the crank angle (hereinafter referred to as "assist start angle")...
