Title:
ENGINE START CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019182301
Kind Code:
A
Abstract:
To make it possible to easily perform start control while suppressing consumption power of a motor with application of a technique for engine start and engine reverse rotation start by the motor.SOLUTION: An engine start control device comprises a motor 20 which can drive an engine 1, an engine control part 41 and a motor control part 42. The motor control part 42 sets a motor torque so that a piston 5a of a gas column 2a during a compression stroke at a stop time is stopped after moved to a prescribed reference position P0 that does not exceed a compression top dead point at a start time of the engine 1. The engine control part 41 operates the motor 20 by the motor torque when a piston stop position of the gas column 2a is on a bottom dead point side with respect to closing timing of an intake valve 11, and thereafter, causes the gas column 2a to burn and causes the engine 1 to temporarily reversely rotate, and then, causes to a gas column 2b during expansion stroke at a stop time to burn and causes the engine 1 to normally rotate. On the other hand, when the piston stop position is on the top dead point side with respect to closing timing of the intake valve 11, control for reverse rotation is not executed.SELECTED DRAWING: Figure 10
