    摘要： A target TH opening degree change amount calculating unit 26 calculates a change amount of a target throttle opening degree ΔTHCMD. In accordance with whether or not the change amount of the target throttle opening degree ΔTHCMD is not less than a predetermined control start threshold, a collision prevention process determining unit 27 determines whether a throttle grip 21 has been operated to rapidly close. When the rapid closing operation of the throttle grip 21 is detected, a change-amount basic value calculating unit 28 calculates a change-amount basic value of the target throttle opening degree. A correction term calculating unit 29 inputs to a multiplying unit 30 a correction term for correcting the change-amount basic value. The multiplying unit 30 multiplies the change-amount basic value by the correction term, and outputs a change amount of the target throttle opening degree thus calculated. The correction term can be set, for example, to have a value not more than 1.0 in accordance with the target TH opening degree.

    摘要： An intake air quantity correcting device calculates an intake air quantity as a sensing target of an airflow meter (an intake air quantity sensor) based on an injection quantity sensing value sensed with a fuel pressure sensor (an injection quantity sensor) and an oxygen concentration sensing value sensed with an A/F sensor (an oxygen concentration sensor). The intake air quantity correcting device regards a difference between the intake air quantity calculation value calculated in this way and an intake air quantity sensing value sensed with the airflow meter as a sensing error of the airflow meter and corrects the intake air quantity sensing value of the airflow meter based on the sensing error.

    摘要： A dish-shaped combustion chamber (14) is formed in a diesel engine piston (13), and a fuel injector (16) is installed on the center axis of this combustion chamber (14). A device (3,41) is provided for varying the intake air amount aspirated into the engine. It is determined whether the engine is an idle running state or a normal running state. The device (3,41) is controlled so that the intake air amount in the idle running state is less than the intake air amount in the normal running state, and the injector (16) is controlled so that part of the fuel is injected before a main injection when the engine is in the idle running state.

    摘要： An intake system for an internal combustion engine, the system having an air tank of a predetermined volume. The tank is connected to a intake pipe of the engine via a first connecting pipe. The tank is connected to an air cleaner via a second connecting pipe. A control valve is arranged at a position where the first connecting pipe is connected to the intake pipe so as to change the effective intake pipe length. The control valve is operated in response to the operating conditions of the engine to select the effective intake pipe length capable of attaining increased volumetric efficiency.

    摘要： A mixture compressing internal-combustion engine having a combustion chamber, an intake conduit for introducing a combustible mixture into the combustion chamber, a throttle valve for controlling the flow of the mixture in the intake conduit and apparatus for reducing knocking in the engine. The knock reducing apparatus includes a knocking sensor coupled to the combustion chamber, control means coupled to the sensor and an adjustable full-load stop positioned within the intake conduit adjacent the throttle valve. The stop is controlled by the control means to vary the full-load opening angle of the throttle by an amount corresponding to the output signal from the control means, a reduction in the full-load opening angle reducing knocking of the engine.

    摘要： A fuel-saving and emission reduction system for internal combustion engines includes electronic carburetor controlling circuitry and a carburetor by-pass system which stops fuel flow to the engine when power from combustion is not required. A normally open by-pass control butterfly valve in the fuel/air passage between the throttle valve and the engine intake manifold is operated by a motor, such as a solenoid or the like, under control of the controlling circuitry and is closed only upon release of the engine throttle and during the period that the vehicle has sufficient speed to assure restart upon reapplication of the fuel/air flow. A carburetor by-pass valve is held in a normally closed position by the combined effects of spring bias and the normal vacuum in the fuel/air passage. When the normally open by-pass control butterfly is closed, the fuel/air vacuum is reduced to permit the spring biased normally closed self-regulating carburetor by-pass valve to admit filtered air at a predetermined reduced vacuum to the engine manifold for continued operation of vacuum accessories and also for reducing the amount of oil drawn past combustion chamber seals and valve guides. Associated with the carburetor by-pass valve is a carburetor vent valve which is simultaneously opened to admit filtered air to the fuel/air passage between the throttle valve and the by-pass control butterfly to thereby eliminate all vacuum that will draw fuel from the carburetor. As a further feature, the electronic controlling circuitry operates to close the by-pass control butterfly for about one-half second upon the opening of the ignition switch to thereby eliminate self-ignition or dieseling and reduced hydrocarbon emissions.
