Abstract:
The present invention comprises a cylinder (4), a piston (5), a cylinder head (6), a combustion chamber (2), an in-cylinder injector (3), an ignition plug (8), an intake port (13), an exhaust port (12), an intake valve (7), an exhaust valve (11), a valve train (14), and a control device (10). The valve train (14) actuates the intake valve (7) and the exhaust valve (11) so that the six strokes including an intake stroke, a compression stroke without ignition, an expansion stroke without combustion, a compression stroke with ignition, an expansion stroke with combustion, and an exhaust stroke are executed in this order. In the compression stroke with ignition, the control device (10) causes fuel to be injected by the in-cylinder injector (3) and passes current to the ignition plug (8). A six-cycle engine can be provided that is capable of realizing stratified-charge combustion while increasing intake air volume.
