摘要： A method and apparatus for exhaust gas recirculation for an internal combustion engine in which exhaust gas is recirculated through a recirculation passage connecting the exhaust passage of the engine and the intake passage of the engine. A vacuum-response type recirculation control valve is disposed in the exhaust gas recirculation passage to operate in response to vacuum detected at a vacuum detection port located in the intake passage in the vicinity of a throttle valve. A vacuum tank is connected through a solenoid-actuated change-over valve to the vacuum passage interconnecting the vacuum detecting port and the recirculation control valve, the vacuum tank being in communication with the intake passage downstream from the throttle valve through a check valve. A differential pressure switch is connected between the solenoid-actuated change-over valve and a power source and is adapted to be placed in "on" state when the vacuum detected at the vacuum detecting port is lower than the vacuum in the vacuum tank to operate the change-over valve to connect the vacuum tank to the vacuum passage.

摘要： An internal combustion engine for a vehicle has an exhaust gas recirculating system for returning exhaust gases to the engine intake passage. The carburetion system for the engine includes a fuel enrichment valve. Sensors for various vehicle speeds and engine operating conditions operate control valves whose actions are modified by a sensor for atmospheric pressure, to control the fuel enrichment valve and a valve in the recirculation passage so that fuel enrichment and exhaust gas recirculation are both reduced when the vehicle travels at a high elevation having low atmospheric pressure.

摘要： An exhaust gas recirculation control system employs a flow rate valve in the recirculation line. The valve is operated by suction pressure obtained from two suction ports in the engine intake passage. Suction lines from those ports contain air inlet valves which dilute the suction pressure with atmospheric air, depending upon engine operating conditions. A fuel supply increasing valve is connected to a venturi in the engine intake passage and suction operated control means control operation of that valve. The result is an improved acceleration characteristic for the engine under load without substantial increase in discharge of pollutants into the atmosphere.

摘要： A control valve in an exhaust gas recirculation line for an engine is operated by vacuum pressure from a regulating valve. The regulating valve has a vacuum chamber positioned between two orifices mounted in a line leading to atmospheric air intake. An air valve located downstream from said regulating valve and orifices controls vacuum pressure from a control suction air line leading to the engine intake passage. The return rate of exhaust gas to the engine is proportional to the flow rate of suction air supplied to the engine, thereby providing a desired exhaust gas return ratio.

摘要： An internal combustion engine for a vehicle has an exhaust gas recirculation system for returning exhaust gases to the engine intake passage. The carburetion system for the engine includes a fuel enrichment valve. A control suction air line from the intake passage operates a regulating valve which controls the exhaust gas recirculation valve as well as the fuel enrichment valve. The flow resistance through the control suction air line is controlled by a prescribed control factor, which factor may depend upon the engine temperature alone or supplemented by engine speed, engine load (suction pressure), or atmospheric pressure.

摘要： A valve operating system in an internal combustion engine includes a cam shaft provided with a valve operating cam, a rocker arm having a pair of support wall portions which are integrally connected at their base ends to a swinging support portion swingably supported on a support member mounted on a cylinder head and which are opposed to each other at a distance in a direction along the swinging axis of the swinging support portion, a support shaft supported between the support wall portions, and a roller which is rotatably supported on the support shaft with a bearing interposed therebetween so as to be in rolling contact with the valve operating cam. A lower connecting wall interconnecting lower portions of the base ends of the support wall portions is projectingly provided on the swinging support portion in a manner opposed to an outer peripheral surface of a lower portion of the roller. Thus, it is possible to increase the rigidity of the rocker arm, while avoiding an increase in size of the rocker arm.

摘要： A method of selectively and automatically adapting an electronic control unit for internal combustion engines, depending upon whether the engine has a manual or an automatic transmission. When the engine has the manual transmission, a first signal indicative of a shift lever position assumed by the manual transmission is always generated. When the engine has the automatic transmission, a second signal indicative of the shift lever position is generated when the automatic transmission assumes a neutral position or a parking position, and the first signal is generated when the automatic transmission assumes a position other than the neutral position or the parking position. When it is determined that the second signal is being generated, second control data is selected to control the operation of the engine, and when it is determined that the first signal is being generated and at the same time the starter is operating, first control data is selected to control the engine operation.
