摘要： An engine control system is disclosed which comprises a means for storing engine control data with such parameters as throttle valve opening angle for regulating the quantity of the air taken into an engine cylinder, an intake manifold depression and an engine speed, a means for reading-out said engine control data with the parameters of the intake manifold depression and the engine speed in light load condition and with the parameters of the throttle valve opening angle and the engine speed in heavy load condition, and a means for controlling the engine using the read-out data. The change of parameter in said system is achieved by using at least one of the throttle valve opening angle, intake manifold depression, engine speed and the engine control data. The locus or the valve of the changing point in parameter replacement from the intake manifold depression to the throttle valve opening angle, or vice versa, may have a hysteresis characteristic. Furthermore, said changing point may be shifted in response to the engine speed.

摘要： An automatic choke valve apparatus for an internal combustion engine comprising a choke valve mounted in an intake passage of an internal combustion engine and having an operation shaft connected to a driving shaft of an external pulse motor through an intermediate torsion spring and through circumferentially disposed front and rear pawls such that drive rotation from the motor can be effected only in the regular direction of rotation thereof. A driving pulse circuit is connected to the pulse motor to drive the same between first through fourth sequential operation conditions by respective detecting of the closure of an engine ignition switch, closure of an engine starter switch, beginning of complete firing of the engine, and continuing of the complete firing. The motor is driven in reverse direction of rotation in the first operation condition and in sequential regular direction of rotation in the second to forth operation conditions. In the first operation condition the motor is driven in predetermined high speed reverse direction of rotation, whereas in the second operation condition, it is driven in the regular direction of rotation for a predetermined constant time interval at a speed corresponding to engine temperature, whereas in the third operation condition, it is driven in regular direction of rotation at a predetermined high speed for a constant time interval, while in the fourth operation condition it is driven in the regular direction of rotation at a speed corresponding to engine temperature.

摘要： The choke flap (2) is turned to the start position by an engine temperature dependent stepping motor (5). In order to provide an increased slow running speed under extreme cold conditions the drive shaft passes the position in which the choke flap is completely closed. a cranked arm fixed to the drive shaft actuates a cam face (18) which is able to press against a second cranked arm provided with an adjuster set screw fixed to the throttle shaft. The cam face has an extra high face (18a) which bears against the set screw (17a) when the drive shaft (6) passes the normal position to give an increased throttle angle.

摘要： The choke flap and throttle valve linkage is actuated by a step motor (5) via a torsion springs. The step motor receives impulses from an impulse transmitter (15) working at a fixed frequency determined by a fixed resistance (16) and a capacitor (17) via a contact breaker (19a) regulated by an actuator (19) whose frequency is controlled by a resistance whose value is varied by engine temperature. The choke flap is opened at a speed corresponding to engine temperature increase rate.
