Engine stop control device for hybrid vehicle

An engine stop control device of a hybrid vehicle comprising:

• a plurality of cylinders, a direct injection engine directly injecting fuel into the cylinders,
• a clutch connecting/disconnecting the direct injection engine to/from a power transmission path, and
• a rotating machine at least acting as an electric motor,
• the hybrid vehicle using the direct injection engine and the rotating machine as a drive power source for running and performing an ignition start for starting the direct injection engine by injecting fuel into the cylinders with a piston stopped in an expansion stroke while an assist torque is provided by the rotating machine,
• when the clutch is interrupted to stop the direct injection engine during running, the once interrupted clutch being temporarily connected at the time of the engine stop or immediately after the engine stop and within a time when a pumping action due to compression of air in the cylinders is acquired, and thereby a crankshaft being separated from a crest of a pumping energy generated near compression top dead center at which a piston in any of the cylinders of the direct injection engine reaches a top dead center after a compression stroke and the crankshaft being stopped automatically at a crank angle defined to correspond to a minimum region of the pumping energy.
