    摘要： An apparatus for controlling air amount upon engine start comprises a control signal generator (22) which provides control signals (θ) indicative of amounts of air required upon start of an internal combustion engine and corresponding to temperatures of the engine. An amount of air required upon engine start is derived from the control signal generator in accordance with an engine temperature upon the engine start to control air amount thereupon.

    摘要： @ A fuel injection system for an internal combustion engine has a fuel injector (10) disposed in a main air passage (33) upstream of a throttle valve (18). A part of air flowing through the main air passage is caused to flow through a by-pass air passage (5, 14) having outlet ports (8) open to the main air passage upstream of the injection orifice of the injector (10). A thermal type air flow meter (7, 9) measures the rate of air flow through the by-pass air passage. In order to prevent whirling-up of injected fuel and resultant adhesion of the fuel to walls adjacent to the by-pass air passage outlet ports (8), the cross-sectional area of the main air passage adjacent to the by-pass air passage outlet ports (8) is determined to be greater than that of the main air passage around the throttle valve (18) when in its fully open position.

    摘要： Disclosed is an electromagnetic type fuel injection valve (10) including a stator iron core (1), an electromagnetic coil (2) concentric with the stator iron core, a casing (4) formed of a magnetizable material and accommodating therein the stator iron core and the electromagnetic coil, a moving body (6, 106) provided at its end with a valve body (6d, 106d), a stopper (7) for the moving body, a valve seat (7a) opposite to the stopper with the moving body interposed therebetween and a spring (9) engaged with an end of the moving body for biasing the same, the moving body being adapted to reciprocate between the valve seat and the stator iron core under the magnetizing force of the electro­magnetic coil and the biasing force of the spring, and having an armature (6a, 106a) adapted to be absorbed by the stator iron core and a rod (6b, 106b) contiguous with the valve body, the armature and the rod being formed of the same material so as to be integral with each other, a guide portion (6c, 106c) of the rod and a portion of the moving body adapted to abut against the stopper being subjected to a hardening treatment, and the electromagnetic absorbing force of the armature being increased by reducing the leak magnetic flux leaking through the rod.
