    摘要: A pump housing supporting a driving shaft has a plurality of cylinder bores extending radially and arranged at substantially regular intervals around an outer periphery of the driving shaft. Each cylinder bore has a plunger fitted therein, which reciprocates in response to a rotation of the driving shaft. An inlet, an inlet valve, an outlet, and an outlet valve are provided for each plunger. Fluid flowing from an inlet port provided in the pump housing flows into each inlet, and moreover, fluid flowing from each outlet passes through an outlet passage and flows into an outlet port provided in the pump housing. The outlet passage has a plurality of communication holes corresponding to the outlet valves. Outlet ends of the communication holes converge on one spot in the pump housing.

    摘要: To allow an engine having an intake duct for drawing running air to produce a high output by performing appropriate fuel injection depending on dynamic pressure variations. A vehicle speed corrective coefficient calculator calculates a fuel corrective coefficient KVPLS based on a vehicle speed VPLS, and a throttle corrective coefficient calculator calculates a corrective coefficient KV&thgr;TH based on a throttle opening &thgr;TH. A corrective coefficient multiplier multiplies the fuel corrective coefficient KVPLS and the corrective coefficient KV&thgr;TH, thus calculating a vehicle speed fuel adjustment corrective coefficient KVAF. An injection time calculator calculates a basic injection time TiM based on the throttle opening &thgr;TH and an engine rotational speed Ne, and also calculates a fuel injection time Ti by reading the vehicle speed fuel adjustment corrective coefficient KVAF and correcting the basic injection time TiM. When the engine rotational speed Ne is equal to or higher than a predetermined value Ne1 and also when the transmission is shifted to a low gear position, a corrective coefficient KVAF signal is applied to the injection time calculator.

    摘要: To enable accurate detection of the alternative ambient pressure when the correction of fuel supply is carried out by the used of the value of the ambient pressure substituted by the negative pressure in the inlet pipe. The difference between the calculated alternative ambient pressure and the estimated ambient pressure (offset) is set as a plurality of functions of the number of engine revolutions and the throttle opening, and stored in the area determination section with a plurality of areas divided by each offset value. In which area the condition of the engine resides is determined from the number of engine revolution and the throttle opening and the offset corresponding to the area is supplied. The calculation section calculates the calculation base value by the use of the negative pressure PB and the offset.

    摘要: An ignition timing control method and apparatus for an internal combustion engine mounted on a motor vehicle can prevent the occurrence of the knocking in the internal combustion engine. When the engine is running within a specific speed range and the transmission gear ratio is high, the control device determines that the engine is running under a condition where knocking is likely to occur. Accordingly retarding of the ignition timing in the internal combustion engine is accomplished in order to prevent knocking.
