摘要： An internal combustion engine having a cylinder, including a main combustion chamber, in combination with a sub-combustion chamber provided with an ignition plug and communicating with the main combustion chamber through a small hole in a cylinder wall for jetting out the flame of air-fuel mixture ignited in the subcombustion chamber to the main combustion chamber, the air-fuel mixture being supplied to the sub-combustion chamber through a suction tube from the same carburetor which feeds the main combustion chamber. The carburetor inlet of said suction tube is positioned upstream of a throttle valve and downstream of a venturi portion of the carburetor. A valve is placed at the outlet of the suction tube to the sub-combustion chamber and this valve may be interconnected with a main valve in the suction manifold leading from the carburetor to the main combustion chamber to move in synchronism therewith and with a piston in the cylinder, or it may be arranged to operate automatically in response to the difference of pressure within the sub-combustion chamber and the suction tube.

摘要： A misfire detecting device for an internal combustion engine includes an exhaust gas introducing tube which comprises tube means having openings at both ends thereof, one opening thereof being provided at a portion adjacent to an exhaust port in an exhaust passage in order to introduce the exhaust gas from a combustion chamber of the internal combustion engine which is of the piston type and the other opening thereof being provided at an exterior portion of the exhaust passage. A pressure transducer having a pressure sensing part is connected to the said other opening of the exhaust gas introducing tube, thereby converting a pressure fluctuation of the exhaust gas introduced by said exhaust gas introducing tube to an electrical signal. A signal processing circuit electrically connected to said pressure transducer detects a predetermined signal from said electrical signal of said pressure transducer. Thus the misfire detecting device converts a flow fluctuation of the exhaust gas in the exhaust passage to an electrical signal with said pressure transducer, detects a portion of the pressure fluctuation based on a misfire of the internal combustion engine from said electrical signal and thereby detects a misfire of the internal combustion engine.
