摘要： A two-stroke engine having an intake valve and an exhaust valve which are arranged on the cylinder head. The peripheral portions of the inner wall of the cylinder head around the intake and the exhaust valves are cut away, and the peripheral portions of the top portion of the inner wall of the cylinder bore around the intake and the exhaust valves are cut away. A masking wall is formed on the inner wall of the cylinder head to mask the valve opening between the valve seat and the peripheral portion of the intake valve, which is located on the exhaust valve side, for the entire time for which the intake valve is open.

摘要： A two-cycle internal combustion engine comprises a cylinder head having an intake port and exhaust port opened to a combustion chamber, to which compressed fresh air is introduced via an intake valve. An inclined concavity is formed on a top face of a piston. An exhaust valve is opened earlier than the intake valve when the speed of the downward movement of the piston is relatively high, so that a part of exhaust gas in the exhaust port flows back to the combustion chamber in that condition. An exhaust gas swirl rotating around a cylinder axis is formed when the exhaust gas flows back and the fresh air is slowly introduced onto the exhaust gas swirl in that condition. The inclined concavity serves to smoothly guide the exhaust swirl.

摘要： A two-cycle internal combustion engine comprises a cylinder head having two intake ports and an exhaust port opened to a combustion chamber, to which compresses fresh air is introduced via two intake valves. The intake and exhaust valves are operated in response to a crank angle. During an idling or light load running condition, an air control valve closes the second intake port. The exhaust valve is opened earlier than the second intake valve, and the first intake valve is opened later than the second intake valve, while the speed of the downward movement of the piston is relatively high. An exhaust gas swirl rotating around a cylinder axis is formed when the exhaust gas flows back into the condition chamber and the fresh air is slowly introduced via the first intake valve onto the exhaust gas swirl in the idling or light load condition. A large amount of fuel is rapidly introduced into the combustion chamber via the second intake valve in a heavy load condition.

摘要： In a double air-fuel sensor system including two air-fuel ratio sensors upstream and downstream of a catalyst converter provided in an exhaust gas passage, an air-fuel ratio correction amount is remarkably changed when the output of the upstream-side air-fuel ratio sensor is switched from the lean side to the rich side or vice versa, and the actual air-fuel ratio is adjusted in accordance with the air-fuel ratio correction amount. The remarkable-change speed of the air-fuel ratio correction amount is changed in accordance with the output of the downstream-side air-fuel ratio sensor.

摘要： Disclosed is a multi-cylinder engine having auxiliary valves in addition to intake and exhaust valves. A common exhaust gas passage is formed in the cylinder head and is connected to each of cylinders via the corresponding branches. Each of the auxiliary valves is arranged in a respective branch and opens at a time of the latter half of the exhaust stroke and at the end of the intake stroke, so that the auxiliary valve of one cylinder opens in synchronization with the opening operation of the auxiliary valve of another cylinder. The valve lift or the opening duration of the auxiliary valves of said one cylinder and another cylinder which are arranged adjacent to each other is set so as to be less than that of the auxiliary valves of said one cylinder and another cylinder which are not arranged adjacent to each another.
