    • In a control device, an engine self-restart means tries the engine restart when an engine restart request is issued while the engine rotation speed is within a first rotation speed range. A pre-gear synchronizing control means executes gear rotation speed synchronization between pinion and ring gears, and then retries the engine restart when the engine restart request is issued while the engine rotation-speed is within a second rotation speed range. A pre-gear meshing control means executes gear-meshing between the pinion and ring gears and then retries the engine restart when the engine restart request is issued while the engine rotation speed is within a third rotation speed range. On detecting the engine-restart failure of the engine self-restart control, the control device prohibits the execution of pre-gear synchronizing control until a predetermined time counted form the failure detection time is elapsed, and executes the pre-gear meshing control after the predetermined time period is elapsed.
    • 在控制装置中,当发动机转速在第一转速范围内时,发动机重启请求被发出时,发动机自重起动装置尝试发动机重起动。 预齿轮同步控制装置执行小齿轮和齿圈之间的齿轮转速同步,然后当发动机转速在第二转速范围内时发出发动机重起请求时重试发动机重起动。 预齿轮啮合控制装置执行小齿轮和环形齿轮之间的齿轮啮合,然后当发动机转速在第三转速范围内时发出发动机重起请求时重试发动机的重启。 在检测到发动机自重启动控制的发动机重起故障时,控制装置禁止执行预齿轮同步控制,直到经过故障检测时间为止计算出的预定时间,并且执行前齿轮啮合控制 经过了预定时间。

    • An exhaust recirculation apparatus is provided to an engine. A high-pressure EGR passage branches from upstream of a turbine of a turbocharger in an exhaust system for recirculating exhaust gas to downstream of a compressor of the turbocharger in an intake system. A high-pressure EGR regulating unit controls exhaust gas through the high-pressure EGR passage. A low-pressure EGR passage branches from downstream of the turbine in the exhaust system for recirculating exhaust gas to upstream of the compressor in the intake system. A low-pressure EGR regulating unit controls exhaust gas through the low-pressure EGR passage. A control unit feedback-controls the high-pressure EGR regulating unit, and open-controls the low-pressure EGR regulating unit when exhaust gas is recirculated through the high-pressure EGR passage and the low-pressure EGR passage. The control unit feedback-controls the low-pressure EGR regulating unit when exhaust gas is recirculated through only the low-pressure EGR passage.
    • 向发动机提供排气再循环装置。 高压EGR通道在排气系统中的涡轮增压器的涡轮机的上游分支,用于将排气再循环到进气系统中的涡轮增压器的压缩机的下游。 高压EGR调节单元控制通过高压EGR通路的废气。 低压EGR通道在排气系统中从涡轮机的下游分支,用于将废气再循环到进气系统中的压缩机的上游。 低压EGR调节单元控制通过低压EGR通路的废气。 控制单元反馈控制高压EGR调节单元,并且当废气通过高压EGR通道和低压EGR通道再循环时,对低压EGR调节单元进行开度控制。 当废气仅通过低压EGR通道再循环时,控制单元反馈控制低压EGR调节单元。
