    Abstract: PROBLEM TO BE SOLVED: To stably burn fuel in a combustion chamber if an average air-fuel ratio of mixture is rich when required load is small. SOLUTION: Low temperature combustion and normal combustion can be selectively performed, and main injection Qm for injecting fuel for mainly driving an internal combustion engine, and auxiliary injection Qv for injecting fuel for promoting combustion of the fuel mainly injected by the main injection can be performed. When it is required to make an air-fuel ratio of exhaust gas emitted from the combustion chamber rich when a required load is smaller than a prescribed value, first combustion is performed at a lean air-fuel ratio at an injection pattern for performing only the main injection at faster timing than a normal injection timing. Then, auxiliary injection is performed at faster injection timing than the timing of the main injection, and first combustion is performed at a rich air-fuel combustion at an injection pattern for performing the main injection at faster timing than a normal injection timing.

    Abstract: PROBLEM TO BE SOLVED: To control a combustion condition of a diesel engine to the optimum condition. SOLUTION: Cylinder pressure sensors 29a to 29d for detecting pressure in a combustion chamber are provided in each cylinder of the diesel engine 1. An electronic control unit (ECU) 20 of the engine calculates a crank angle θmax at which product PV of cylinder pressure and actual cylinder volume becomes the maximum value, calculates a period ΔT from the start of fuel injection to θmax, and feedback-controls opening of an EGR valve 35 for adjusting amount of EGR gas supply to the engine so that the calculated ΔT becomes a target value decided based on current opening of an accelerator and the number of revolutions of the engine. Since ΔT can be computed without increasing computation load of the electronic control unit 20 of the engine, it is possible to control amount of EGR gas (EGR rate) to the optimum value accurately without increasing computation load.

    Abstract: PROBLEM TO BE SOLVED: To provide a technique for performing auxiliary injection while suppressing damage to a piston, when a fuel injection means of an internal combustion engine performs auxiliary injection in addition to main injection. SOLUTION: If need for a temperature rise control of an exhaust system is determined in a step S101, and a light/medium load range of an operational status of the internal combustion engine 1 is determined in a step S102, at least any one of operation is performed as follows: reducing opening of a nozzle vane of a turbocharger; throttling an exhaust throttle valve; and controlling a VVT mechanism.
