Accordingly, a precise cylinder inflow air amount can be obtained by correcting the cylinder inflow air amount while taking actuation delay of the variable valve mechanism into account.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that a multidimensional map of which axes are at least a revolution number, a load, valve timing, and the atmospheric pressure is required to take into consideration influence of an amount of highland correction, in which the atmospheric pressure is reduced, in structure calculating the controlled variables of ignition timing based on the revolution number, load, and valve timing so that the scale of the map mounted on an ECU becomes large to increase required memory capacity. SOLUTION: The control device calculates a packing efficiency reference value and an EGR amount reference value based on a polynominal expression using at least the revolution number, intake absolute pressure, the atmospheric absolute pressure or exhaust absolute pressure, and variable valve controlled variables as input, and performs highland correction by a ratio of the intake absolute pressure to the atmospheric absolute pressure. Under a highland condition in which the highland-corrected atmospheric pressure is decreased, a fuel injection amount is calculated based on the highland-corrected packing efficiency, and ignition timing is calculated based on the revolution number, highland-corrected packing efficiency, and the highland-corrected EGR amount.

摘要： PROBLEM TO BE SOLVED: To provide a combustion controller of a spark-ignition multi-cylinder engine capable of accurately correcting dispersion in produced torque between cylinders.
SOLUTION: An ignition timing MBT where the produced torque is maximum is obtained for each cylinder. The averaged value of the produced torques for the cylinders generated when the engine is ignited at the ignition timings MBT or at the ignition timings obtained by correctively delaying the ignition timings MBT is determined as the target torque. The ignition timing, fuel injection amount, and cylinder intake air amount are corrected for each cylinder so that the produced torque of each cylinder reaches the target torque. When the produced torque of each cylinder matches the target torque, the target idle rotational speed is reduced.

摘要： PROBLEM TO BE SOLVED: To surely determine a misfire and knocking of each cylinder of an internal combustion engine.SOLUTION: A metal washer 44 is provided with a semiconductor strain sensor 20 to detect an axial displacement of an ignition plug 5 caused by an in-cylinder pressure of each cylinder of the internal combustion engine. The misfire is determined by comparing output signals of the respective strain sensors 20 or integrated values of the output signals of the respective strain sensors 20 on explosion strokes of the respective cylinders, with a threshold, and the knocking is determined by extracting detected values in a particular frequency band for the knocking and comparing the integrated values in the frequency band, with a threshold. Since the misfire and the knocking are directly detected from a strain around a combustion chamber, the misfire and the like can be determined under a wide range of operating conditions. A strain sensor 20 may be arranged between two cylinders; therefore, combustion states of all the cylinders can be detected by a smaller number of strain sensors 20 than the number of cylinders.
