摘要： A system for suppressing discharge of evaporated fuel gas is adapted to introduce the evaporated fuel gas generated in a fuel tank of an internal combustion engine into an intake passage, to suppress the discharge of the evaporated fuel gas into the atmosphere. The system comprises an evaporated fuel gas passage allowing the evaporated fuel gas within the fuel tank to be introduced into the intake passage and a controller variably controlling a cross-sectional area of the evaporated gas passage depending upon an operating condition of the engine. The cross-sectional area of the evaporated gas passage is controlled according to an amount of fuel supplied to the engine. In addition, the cross-section area of the evaporated gas passage may be controlled in response to the operating condition of the engine and may be controlled according to a preliminarily set comparative rotational speed in an idling condition of the engine. Alternatively, the cross-sectional area of the evaporated gas passage may be controlled correspondingly to the operating condition of the engine and, in addition thereto, may be controlled to assume either one of a fully open position and a fully closed position in response to the operating condition of the engine.

摘要： An internal combustion engine control apparatus which infers opening and closing of a throttle valve upon failure of throttle detecting switch. A programmed computer calculates basic fuel injection amount in accordance with detected rotational speed and air flow and discriminates failure of the throttle detecting switch when output of the throttle detecting switch does not correspond to the calculated basic fuel injection amount and the detected rotational speed. When the computer discriminates failure of the switch, the computer infers opening and closing of the throttle valve by comparing the calculated basic fuel injection amount with a reference value indicative of normal fuel injection amount closed throttle. The reference value is a function of the rotational speed and updated by the calculated basic fuel injection amount under closed throttle condition.

摘要： An improved fuel injection control apparatus, in which a reference pressure is provided to a pressure regulator, for simplifying the fuel supply system by preventing the fuel quantity injected from injection valves into an engine from being influenced by variations in the air intake pressure. A pressure regulating device disposed in a fuel supply pipe between a fuel pump and the fuel injection valve regulates the pressure of fuel supplied from the fuel pump to the fuel injection valve so that the pressure is proportional to the predetermined pressure, without returning fuel from the injection valve to the fuel tank. An intake pressure detecting device detects the pressure in the intake pipe, and a fuel injection quantity correcting device corrects the fuel injection quantity according to deviations of the fuel pressure regulated by the pressure regulating device from a proper value due to the differential pressure between the pre-determined pressure of the pressure regulating means and the intake pressure. Accordingly, he fuel injection quantity injected from the injection valve is corrected based on the operating condition of the engine due to the variation of the intake pressure. As a result, the fuel supply system is simplified.

摘要： A fuel control system for internal combustion engines is disclosed in which a high temperature re-start state is determined based on a physical volume detecting device and a starting state detected by a start state detecting device. A compensation value is determined so as to compensate the amount of fuel supplied during re-start under high temperatures. The compensation value is determined by routines performed within a central processing unit. Variables that affect the compensation value include the physical volume, an internal pressure of a suction pipe, and the starting state of the engine. The compensation value ensures that fuel injection in the engine occurs over an appropriate timing.

摘要： A fuel supply system of an internal combustion engine includes, a fuel return branch connection positioned downstream of a fuel filter. The branch connection returns part of the fuel which passed the fuel filter back into the fuel tank. An end of the fuel return connection is extended to the bottom of the fuel tank. A throttle part for controlling returned fuel flow is positioned in the branch connection. Because part of fuel which passed the fuel filter is returned into the fuel tank, fuel in the fuel tank is repeatedly filtered by the fuel filter. Thus, removal of dust in the fuel is improved and total fuel flow passing through the fuel pump is increased. This improves cooling of the fuel pump and thus helps prevent vapor generation while also improving durability of the pump.
