TH34565A - Spark-ignition two-stroke internal combustion engine with an internal combustion regulator. - Google Patents

Abstract

The DC60 is a two-stroke, spark-ignition internal combustion engine (1) incorporating a combustion regulator that allows for the self-ignition of the fresh air-fuel mixture in the combustion chamber (16) to occur at least during low-load operating conditions by controlling the exhaust port inlet (15) or the opening of the exhaust port (15) using the exhaust control valve (24), depending at least on the rotational speed of the internal combustion engine or the throttle valve opening. Combustion chamber volume adjustment pathways (19, 20) are provided for changing the volume of the combustion chamber (16) depending on the operating conditions of the internal combustion engine (1). By the operation of the exhaust control valve (24), the fresh air-fuel mixture in the combustion chamber (16) is allowed to occur by self-ignition at least during low-load operating conditions. The two-stroke, spark-ignition internal combustion engine (1) incorporating a combustion regulator that allows for the self-ignition of the fresh air-fuel mixture in the combustion chamber (16) to occur at least during low-load operating conditions. A fresh air-fuel mixture in the combustion chamber (16) is achieved at least during low-load operating conditions by controlling the exhaust port inlet (15) or the opening of the exhaust port (15) using the exhaust control valve (24), depending at least on the rotational speed of the internal combustion engine or the throttle valve opening. Combustion chamber volume adjustment pathways (19, 20) are provided for changes in the volume of the combustion chamber (16) depending on the operating conditions of the internal combustion engine (1). By the operation of the exhaust control valve (24), the fresh air-fuel mixture in the combustion chamber (16) is achieved by self-ignition at least during low-load operating conditions.
