    • A multi-cylinder engine includes a plurality of combustion chambers and employs an improved intake pressure sensor arrangement to control fuel injection into the combustion chambers. A plurality of intake conduits define intake passages through which air flows to the combustion chambers. An intake pressure sensor senses intake pressure within the intake passages. A plurality of first conduits are coupled with an accumulator independent of one another and a second conduit is also coupled with the accumulator. The first conduits connect the accumulator to the respective intake passages. The second conduit connects the accumulator to the intake pressure sensor. A control device controls the amount of fuel injected into the combustion chambers based upon at least a signal from the intake pressure sensor.

    • A system for controlling a fuel injector in accordance with an injection control strategy for an engine includes programmable control logic to provide selectable threshold signals for comparator circuits and/or control logic configured to receive various control signals in the control circuit and determine one or more timing signals. The programmable control logic allows the drive circuit to be modified, without changing any hardware, to accommodate injectors having different characteristics and to change the pulse modulation strategy. The control logic that receives the control signals produces injection timing signals to allow enhanced monitoring and control over the fuel injection process.

    • In a fuel-injection method and an apparatus therefor, an output timing of a injection command signal is decided in such a manner that a fuel-injection timing is in matching with a basic desired injection timing, thereby to help ensure the improvement in the exhaust gases performance ˜of the engine. The invention includes the apparatus to perform the steps of obtaining pressure data by filtering waveforms of the detected common rail pressure, calculating an approximate straight line Ld by the pressure data from a preselected time to a time T3 of at least the first smallest value after the start of the pressure drop, and defining a time, at which a difference between a pressure data and an approximate straight line Ld is the largest value, as the timing T2 of the start of the pressure drop. Based on the time T2, a time lag &Dgr;Td is calculated, that spans from an output timing T0 of injection command signal to a fuel-injection timing T1. The output timing T0 of injection command signal defined at a time of going backwards by the time lag &Dgr;Td from a basic desired injection timing Td, which is obtained in accordance with the engine operating conditions.

    • When a leakage fault occurs in the evaporated fuel processing system of a fuel tank, a control system reliably prevents leakage of the evaporated fuel from the point where the leakage fault has occurred. The fuel tank and a canister are connected to each other via a charge passage having a bypass valve, and the canister and an intake passage of an engine are connected to each other via a purge passage having a purge control valve. When a leakage fault occurs in the fuel tank (or the charge passage upstream of the bypass valve), the bypass valve and the purge control valve are opened and an atmosphere release control valve provided on the canister, is closed. The closure of the atmosphere release control valve stops the negative intake pressure of the engine from being consumed by the intake of air through the atmosphere release control valve, and thus it is possible to efficiently prevent the evaporated fuel from leaking from the point where the leakage fault has occurred by effectively transmitting the negative intake pressure to the point where the leakage fault has occurred.
    • 当在燃料箱的蒸发燃料处理系统中发生泄漏故障时,控制系统可靠地防止从发生泄漏故障的点泄漏蒸发的燃料。 燃料箱和罐通过具有旁通阀的充气通道彼此连接,并且发动机的罐和进气通道经由具有清洗控制阀的吹扫通道相互连接。 当燃料箱(或旁通阀上游的充电通道)发生泄漏故障时,旁通阀和净化控制阀打开,并且设置在罐上的气氛释放控制阀关闭。 大气释放控制阀的关闭阻止发动机的负吸入压力被通过大气释放控制阀的空气吸入而消耗,因此可以有效地防止蒸发燃料从泄漏点泄漏 通过有效地将负吸入压力传递到发生泄漏故障的点,已经发生故障。
