摘要： A four stroke internal combustion engine has a gas reserving chamber 100 which communicates with an exhaust port 31 and is configured to reserve burned gas discharged from a combustion chamber. The burned gas flows into the gas reserving chamber 100 while an exhaust valve including a valve head 32a and a stem 32b is opened in an expansion stroke. The burned gas reserved in the gas reserving chamber 100 is discharged to the combustion chamber while the exhaust valve is opened in an intake stroke.

摘要： An entire peripheral surface of a port bent portion (5) of a direct intake port (2) has a peripheral side surface portion (11) close to a cylinder axis (10). The peripheral side surface portion (11) provides a projection (12) for deviating intake air current (A) from the peripheral side surface portion (11) toward an opposite peripheral side surface portion (13). Further, the bent portion (5) has a peripheral side surface portion (14) close to an upper end surface (9) of a cylinder chamber (8), which provides a projection (15) for deviating the intake air current (A). This projection (15) turns a direction of the intake air current (A) from a peripheral side surface portion (14) close to the upper end surface (9) of the cylinder chamber (8) toward an opposite peripheral side surface portion (16).

摘要： An internal combustion engine and method for operating the engine wherein a leaner than stoichiometric air/fuel ratio is maintained under all running conditions. The desired torque curve is obtained by increasing the amount of boost generated to the intake air charge without enrichening the air/fuel mixture. In addition, an anti-knocking system is incorporated that avoids knocking by retarding the spark advance and, at the same time, providing a leaning in the air/fuel mixture.
