摘要： The present invention relates to a variable operation angle mechanism that can improve engine performance at transient operation by optimally setting a ratio between change amounts of opening and closing timings accompanying a variation in valve operation angle of intake valve, and relates to an apparatus for and a method of controlling an engine including the variable operation angle mechanism. In the variable operation angle mechanism, ratio RIVO of change amount of opening timing IVO of intake valve to change amount of valve operation angle is set to be 20% or more and 40% or less, and preferably, to be 30%. In engine including a variable valve timing mechanism varying a rotating phase of intake camshaft relative to crankshaft and the variable operation angle mechanism, a target phase change amount varied by the variable valve timing mechanism is corrected for phase change amount accompanying the variation in the valve operation angle.

摘要： The present invention relates to an apparatus for and a method of controlling a variable valve timing mechanism. The valve timing mechanism changes over between a first cam for which the closing timing IVC of the intake valve is after intake bottom dead center, and a second cam for which the closing timing IVC is closer to intake bottom dead center than the closing timing IVC with the first cam. Here at the time of stopping the internal combustion engine, the valve timing mechanism changes over to the first cam, and the initial intake stroke performs operation at low effective compression ratio. In the second and subsequent intake strokes, the valve timing mechanism changes from the first cam to the second cam.

摘要： The present invention is related to an apparatus for and a method of controlling an engine provided with: a variable operation angle mechanism that is provided for varying a valve operation angle of an engine valve driven by a camshaft, and is capable of varying a center phase of the valve operation angle in response to a variation in the valve operation angle; and a variable valve timing mechanism provided for varying a rotating phase of the camshaft relative to a crankshaft of the engine, in which a target valve operation angle and a target rotating phase is calculated based on the engine operating state, and a correction value for correcting the target rotating phase based on the target valve operation angle is set. Then, the target rotating phase is corrected by the correction value, thereby controlling the variable valve timing mechanism based on the corrected target rotating phase.

摘要： A gas sensor element includes a main body and a protective layer. The main body has four plane portions and four corner portions each of which is formed between one adjacent pair of the plane portions. The four corner portions include a pair of first corner portions that are formed on a porous diffusion-resistant layer side in a lamination direction of the main body and a pair of second corner portions that are formed on a heater layer side in the lamination direction. The protective layer is comprised of an inner protective layer that covers at least the first corner portions of the main body and an outer protective layer that covers the entire outer periphery of the main body and the inner protective layer. The protective layer has a larger average thickness at the first corner portions than at the plane portions of the main body.

摘要： A control apparatus for an internal combustion engine where the inside of a combustion chamber is divided into a layer of internal EGR gas and a combustible layer to perform stratified combustion. In a port-injected engine equipped with first and second intake valves, the opening timing of the first intake valve is set before a top dead center (TDC) and the opening timing of the second intake valve is set after the TDC, and the closing timings of the first intake valve and the second intake valve are set after a bottom dead center. Then, fuel injection toward the first intake valve is started after the EGR gas, which was blown back to the intake port upstream of the first intake valve, is drawn into the combustion chamber after the top dead center.
