    摘要: An acceleration sensor includes a frame having a hollow space at an inside thereof, four beams extending from the frame to the hollow space, four plummets connected to ends of the four beams, and four sensing units provided on the four beams. One ends of the beams is connected to portions of the frame opposite to each other with respect to the hollow space. The two plummets face each other across the center of the hollow space. One ends of the other two beams are connected to portions of the frame opposite to each other with respect to the hollow space. The other two plummets face each other across the center of the hollow space. This acceleration sensor reduces variations and temporal changes in its sensitivity.

    摘要: At least an engine speed, an opening of an accelerator and an amount of an intake air are detected as an engine operating condition. A standard volume for injecting fuel oil is calculated on the basis of at least the engine speed and the opening of the accelerator. A target injection timing of fuel is set on the basis of the engine speed and the standard volume for injecting fuel oil. An actual fuel injection timing is detected. A standard target EGR rate is calculated on the basis of the engine speed, the amount of the intake air and the standard volume for injecting fuel oil. An amount of adjustment of a target EGR rate is calculated on the basis of the standard volume for injecting fuel oil, the target fuel injection timing and the actual fuel injection timing. A final target EGR rate is set on the basis of the standard target EGR rate and the amount of adjustment. An EGR is controlled on the basis of the final target EGR rate.
