    • PROBLEM TO BE SOLVED: To determine whether or not failure exists in an EGR device, an injection valve for supplying fuel into an intake passage, and an injection valve for supplying the fuel into cylinders, respectively, and when failure exists, take adequate measures according thereto. SOLUTION: A control apparatus for an internal combustion engine includes an in-passage injection valve for injecting the fuel into the intake passage; and an in-cylinder injection valve for injecting the fuel into the cylinders. The control apparatus stops the supply of EGR gas when failure exists in the air-fuel ratio of exhaust gas. When the air-fuel ratio of the exhaust gas thereafter is normal, the control apparatus determines that failure exists in the EGR device, and inhibits the supply of the EGR gas. When failure exists in the air-fuel ratio of the exhaust gas, the control apparatus performs feedback control while supplying the fuel only from either of the injection valves. When the learning value at this point exceeds a predetermined value, the control apparatus determines that failure exists in the injection valve performing the fuel supply. When failure exists in the in-passage injection valve, the control apparatus stops the fuel supply from the injection valve, and changes the operating point to a high-rotation and low-load side.

    • PROBLEM TO BE SOLVED: To provide a control system for an internal combustion engine by which at the time of return from a fuel cut (FC), occurrence of misfire is controlled by positively raising the threshold for misfire with reference to the concentration of residual burned-gas in the combustion chamber.
      SOLUTION: The opening degree of an EGR-valve and timing for valve-opening of an intake-valve are controlled respectively, usually, according to operation conditions of the internal combustion engine, to a normal opening and to a normal timing. Whereas, in the course of FC, or within a specific period after return from FC, opening degree of the EGR-valve is maintained at zero; while, when the timing for opening the intake valve is controlled in the intake stroke toward the retard side farther than in the normal timing, and toward the retard side farther than the exhaust valve-closing timing (control for intake-valve retard-opening). Thus, pressure difference between the front and the rear of the intake-valve directly after opening of the intake valve is increased, and the intake air flow immediately after the opening of the intake-valve is increased. As a result, atomization of fuel spray to be mixed with intake air is accelerated to raise the misfire limit for the residual burned-gas concentration, and occurrence of misfire at FC return, where misfire is easy to occur, is suppressed.

    • 要解决的问题:为了提供一种用于内燃机的控制系统,通过该控制系统,在从燃料切断(FC)返回时,参照集中度积极提高失火阈值来控制失火的发生 的燃烧室中的残余燃烧气体。 解决方案:EGR阀的开度和进气阀的开阀正时通常根据内燃机的运行条件分别控制到正常的开度和正常的定时。 而在FC过程中,或在FC返回后的特定时期内,EGR阀的开度保持为零; 而当进气阀的打开定时被控制在比正常定时更远的阻力侧的进气冲程中,并且朝向与排气门关闭正时(进气阀延迟开启的控制)更远的延迟侧, 。 因此,直接在进气门打开之后的进气门的前后的压力差增加,并且进气阀开启之后的进气量增加。 结果,加速了与进气混合的燃料喷雾的雾化,从而提高残留燃烧气体浓度的失火极限,并且抑制了容易发生失火的FC返回时发生失火。 版权所有(C)2010,JPO&INPIT
