摘要： It is intended to detect combustion state of an internal combustion engine over the entire range where positive torque is generated. Time required from a predetermined first crank angle to a second crank angle is measured by detecting a rotation angle of a ring gear or plate with engine speed detecting means 101. Then, a combustion state parameter is calculated from said required time by combustion state detecting means 102 with an established calculation method, and combustion state is determined by combustion state judging means 103. Engine speed correction means 104 determines and feeds back a correction value for the combustion state detecting value to correct the engine speed. At the moment, the correction quantity for correcting the required time is varied so that the normal combustion value of said combustion state parameter is at a predetermined value or less, or within a predetermined range. When the combustion state parameter reaches a value indicating misfire, update of the correction value is inhibited for a prescribed duration before and after it.

摘要： A main passage mounting a throttle valve and an air bypass flow passage for reducing HC emission by promoting atomization of the fuel spray injected from the assembly pipe fuel injector are integrated in a body of an intake air control device arranged upstream of an assembly pipe in a one-piece structure to form a unit. Thereby, the intake air control device can be easily manufactured and easily mounted on and dismounted from the intake air system. The amount of HC emitted during warming-up operation of an internal combustion engine is reduced by efficiently supplying fuel spray injected from an assembly pipe fuel injector at the time of starting and warming-up operations for the internal combustion engine.

摘要： A combustion state detection system for an internal combustion engine in which a timing signal associated with the rotation of the crankshaft by a predetermined angle is detected and corrected, and a combustion state parameter is calculated from the timing signal. Further, the deviation of the calculated combustion state parameters for normal combustion is detected between the cylinders, and the correction amount of the timing signal is calculated. A reference cylinder is determined by the means for detecting the deviation. The deviation is detected between the combustion state parameter for normal combustion of the reference cylinder and the cylinder opposed thereto and the combustion state parameter for normal combustion of the remaining cylinders. The correction amount is calculated in such a manner as to control the correction amount to not more than a predetermined value or to zero from the detected deviation.
