PURPOSE:To reduce the amount of generation of NO2 and CO and improve combustion performance by forming an exhaust recirculation passage into the body wall of an engine body and allowing the starting edge of the exhaust recirculation passage to communicate to an exhaust port and allowing the terminal edge to communicate to a suction port. CONSTITUTION:A suction port 11 and an exhaust port 12 which are formed into the body wall 6a of a cylinder head 6 communicate through a recirculation passage 16. In said recirculation passage 16, the starting edge 16a is opened at the exhaust port 12, and the terminal edge 16b is opened at the suction port 11, and a flow-rate control valve 15 is installed at the starting edge 16a. The opening-degree of the flow-rate control valve 15 is controlled by a flow-rate controller 20 consisting of a sensor 17 for detecting the revolution of an engine and a control circuit 19 for controlling an actuator 18 on the basis of the revolution detection signal supplied from the sensor 17. Therefore, the ventilation resistance for the exhaust recirculation gas can be reduced by reducing the length of the recirculation passage 16, and since the exhaust recirculation gas can be kept at high temperature, the aimed purpose can be achieved.

92 Mixture thickener for carburetor JP10542882 1982-06-21 JPS58222948A 1983-12-24 KITAMURA SHIYUUICHI
PURPOSE:To decrease the total height of a carburetor, by heightening the mixture concentration of the carburetor in the starting and cold running of an engine without using a choke valve. CONSTITUTION:Sucked air sent from a pump 22 has its pressure regulated to a prescribed level by a constant pressure valve 23 and then jets out at a high speed through an orifice 30 and an ejecting section 31 so that intense negative pressure is caused at a pressure drop section 32. Since the negative pressure in a pressure introducing chamber 21 is made more intense than conventional cases and a sucked air flow rate detector 6 heightens the degree of opening of a Venturi valve 4, the effective cross-sectional area of a fuel jet 9 is made larger than the conventional cases so that the mixture concentration of a carburetor is increased in the starting and cold running of an engine. The high speed of the flow jetting from the ejecting section 31 is controlled by the orifice 30 and a regulating rod 29 depending on the temperature of the engine.

PURPOSE:To increase or decrease an exhaust gas recirculation ratio in accordance with the heavy or light load of an engine by a method wherein an EGR valve, meausring the amount of the recirculation of the exhaust gas, is controlled by an EGR control valve so as to make the pressure difference between the fore part and the hind part of the EGR valve constant. CONSTITUTION:The exhaust gas, taken out of an exhaust pipe 3, is recirculated to a suction pipe 2 through an introducing passage 5, a choking section 6, a pressure chamber 7 and the EGR (exhaust gas recirculation) valve 8. The amount of the recirculation thereof is determined by the opening area of the valve 8 and the pressure difference between the fore part and the hind part of the valve while the amount of suction air is determined by the opening area of a throttle valve 4 and the pressure difference between the fore part and the hind part of the valve. On the other hand, in the EGR control valve 11 controlling the flow amount of the choked section 6, the valve element 18 thereof is moved to control the pressure in the pressure chamber 7 so that the pressure difference between an EGR gas chamber 13 and a vacuum chamber 14 is balanced with a constant value determined by the effective area of a diaphragm 12 and the initial load of a spring 15. When the negative pressure of the suction air becomes lower than the predetermined value thereof, a check valve 25 is closed to shut off the EGR gas and thereby preventing the reduction of the output of the engine.
