    摘要: A fuel vapor control device having a valve opening and closing a passage connecting a carburetor and a charcoal canister according to a predetermined temperature. A first coil spring formed by a "shape memory effect" alloy is provided to urge the valve to open the passage when the temperature is high. A second coil spring urges the valve to close the passage. A solenoid is provided to urge an armature against the valve to close the passage against the force of the first coil spring when the engine is running. The solenoid heats the first coil spring to generate a spring force therein when the engine is running. When the engine is turned off, the solenoid is deactivated, and the force of the first spring overcomes the force of the second spring to open the passage until such time as the temperature of the first spring drops below the predetermined temperature.

    摘要: An ignition timing change-over device for an internal combustion engine comprising a vacuum advancer for causing rotation of the breaker plate of the contact breaker toward an ignition timing advancing direction, a vacuum retarder for causing rotation of the breaker plate toward an ignition timing retarding direction, a first valve unit connected to the vacuum advancer and vacuum retarder, and a second valve unit connected to the vacuum retarder and the first valve unit. The first valve unit is used for supplying the suction vacuum into the vacuum advancer when the temperature of the engine is lower than a predetermined value, supplying the suction vacuum into the vacuum retarder when the engine temperature is higher than the predetermined value, and supplying the suction vacuum into the vacuum advancer when the engine temperature is higher than the predetermined value and the vacuum in the intake manifold is higher than a predetermined value, while the second valve unit acts to permit communication between the vacuum retarder and the atmosphere when the vacuum in the intake manifold is higher than the predetermined value and to permit communication between the vacuum retarder and the first valve unit when the vacuum in the intake manifold is lower than the predetermined value, so that the ignition timing can be changed depending on variations of the two variables, that is, the engine temperature and the intake manifold vacuum.

    摘要: Disclosed herein is an internal combustion engine provided with an exhaust gas recirculation system of so-called back pressure control type. The exhaust gas recirculation system is provided with a vacuum line connecting a so-called EGR port with a vacuum operated flow control valve, and a modulator valve having a control chamber selectively opened to the vacuum line in response to the pressure of recirculated exhaust gas for controlling vacuum signal level of the flow control valve. The control chamber of the modulator is connected to another vacuum signal port located slightly above the EGR port.

    摘要: Disclosed herein is a back pressure control type EGR system for an internal combustion engine, wherein a vacuum modulator has an air introducing chamber which is selectively opened, in accordance with the pressure of recirculated exhaust gas, to a vacuum line connecting an EGR port with a vacuum operated flow control valve. The air introducing chamber is further connected to another vacuum port formed slightly above the EGR port via another vacuum line. Switching valve devices responsive to the temperature of the engine are located on the vacuum lines for stopping the EGR operation when the engine is cold.
