  "textContent": "A six-stroke engine includes a cylinder (4), a piston (5), a cylinder head (6), a combustion chamber (2), a cylinder injector (3), a spark plug (8), an intake port (13), an exhaust port (12), an intake valve (7), an exhaust valve (11), a valve gear (14), and a control device (10). The valve gear (14) operates the intake valve (7) and the exhaust valve (11) to execute 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 in the order named. The control device (10) causes the cylinder injector (3) to inject fuel and energizes the spark plug (8) in the compression stroke with ignition. It is possible to provide a six-stroke engine capable of realizing stratified charge combustion while increasing the intake air volume.",
