摘要： An exhaust gas recirculation system for an internal combustion engine comprising an exhaust gas recirculation passage for recirculating exhaust gases from an exhaust pipe into an intake pipe downstream of a throttle valve, a control valve responsive to a pressure signal for opening or closing said recirculation passage, a pressure chamber defined within the recirculation passage, a negative pressure control valve to which is transmitted a negative throttle pressure generated at a throttle port at a position upstream of the throttle valve when the latter is completely closed and which controls said negative throttle pressure in response to the load on the engine, and a modulator wherein the pressure from the pressure chamber acts on one surface of a diaphragm while the negative output pressure from the negative pressure control valve acts on the other surface of the diaphragm so that the modulator may control the pressure signal in response to the difference between said two pressures acting on the diaphragm, whereby the amount of exhaust gases recirculated may be made proportional to the load on the engine regardless of the variation in rotational speed of the engine.

摘要： A system for heating the intake pipe of an internal combustion engine including a combustion equipment disposed adjacent to the intake pipe, a fuel supply system for supplying the fuel into the combustion equipment and an air supply system including an air pump for charging the air into the combustion equipment, the intake pipe being heated by the heat generated by the combustion of the air-fuel mixture in the combustion equipment. The fuel supply system includes a main fuel injection nozzle and an auxiliary fuel injection nozzle which is controlled by control means so as to start or stop the fuel injection depending upon the operating conditions of the engine. When the engine is started, both the main and auxiliary fuel injection nozzles inject fuel so as to attain the rapid heating of the intake pipe, but when the temperature of the intake pipe exceeds a predetermined level, the injection by the auxiliary fuel injection nozzle is stopped. The heating system further includes a secondary air supply line interconnecting the air pump and the exhaust manifold of the engine and control means for controlling the flow rate of the secondary air in response to the negative pressure in the intake pipe, thereby controlling the flow rate of the air to be charged into the combustion equipment.
