    • A reciprocating internal combustion engine (10) includes an in-cylinder pressure sensor (34) and a crank angle sensor (42). Data of calculated heat release amount Q in synchronization with crank angle is calculated using in-cylinder pressure P after absolute pressure correction. An amount of heat release amount variation ”Q is calculated as a difference between a first calculated heat release amount Q 1 at a first crank angle ¸ 1 on an advanced side of TDC and a second calculated heat release amount Q 1 at a second crank angle ¸ 2 symmetrical to ¸ 1 about TDC. An actual heat release amount Qt is estimated based on the amount of heat release amount variation ”Q calculated using, as the first crank angle ¸ 1 , a crank angle on an advanced side of a combustion start point and using, as the second crank angle ¸ 2 , a crank angle on a retarded side of a combustion end point.
    • 往复式内燃机(10)包括缸内压力传感器(34)和曲柄角传感器(42)。 在绝对压力校正后,使用缸内压力P计算计算出的排放量Q与曲柄角同步的数据。 散热量变化量Q被计算为在TDC的前进侧的第一曲柄角度¸1处的第一计算放热量Q 1与第二曲柄角度的第二计算放热量Q 1之差 ¸2对称于¸1关于TDC。 基于使用燃烧起点的前方侧的曲柄角作为第一曲柄角¸1算出的散热量变化量Q的使用量,作为第二曲柄角度,推定实际放热量Qt ¸2,燃烧终点延迟侧的曲柄角。

    • Provided is an after-treatment apparatus for exhaust gas right after a combustion chamber, which apparatus comprises a discharge device with an electrode exposed to an exhaust port installed in a cylinder head, an antenna installed on the back face of a valve head, an electromagnetic wave transmission line installed in a valve stem with one end connected to the antenna and the other end, covered with an insulator or dielectric and extending to and connected to a power-receiving portion, which is positioned at a location fitting into the guide hole or at a location farther from the valve head in the valve stem, and an electromagnetic wave generator for feeding electromagnetic waves to the power-receiving portion. The after-treatment apparatus is configured such that discharge is generated with the electrode of the discharge device and electromagnetic waves fed from the electromagnetic wave generator through the electromagnetic wave transmission line are radiated from the antenna.
