<p>A hybrid vehicle (10) comprises an eight-cylinder direct-injection engine (12) in which, if it is assumed that the piston (110) of one of the cylinders (100) has stopped at the compression TDC, the immediately preceding cylinder (100) is in the expansion stroke and the exhaust valve (108) thereof is in a closed state. In this hybrid vehicle, at the time of stopping the direct-injection engine (12) by disconnecting a K0 clutch (34) during vehicle drive, the piston (110) of one of the cylinders (100) is made to stop at a crank angle (F) near the compression TDC thereof by temporarily connecting the once-disconnected K0 clutch (34) and rotating the crankshaft (114). In this case, the crank angle (F) of the immediately preceding cylinder (100) will be around 90° greater than the compression TDC, and ignition startup can be performed suitably by injecting fuel into and igniting this cylinder (100). Because ignition startup can be performed even in cases where one of the cylinders (100) has been stopped at an intermediate position in the expansion stroke (around 45° greater than the compression TDC), the application range of ignition startup is widened and the degree of freedom in control is increased.</p> |
