START CONTROLLER, ENGINE SYSTEM, VEHICLE AND METHOD FOR STARTING A COMBUSTION ENGINE

The start controller for an engine includes: stop position detection means that detects a position of a piston in each cylinder in an engine stop time; intake pressure detection means that detects an intake pressure as a pressure in an intake passage; and a determination section that determines whether the position of the piston in each of the cylinders detected by the stop position detection means is within a specified target range X0 after the engine is stopped. In the case where it is determined that the position of the piston in each of the cylinders after the engine stop is out of the target range and the intake pressure detected by the intake pressure detection means is lower than an atmospheric pressure, the engine is started by start means even when an engine start condition is not satisfied.
