摘要： A control system for an internal combustion engine having fuel injectors for injecting fuel into a combustion chamber of the engine. A fuel property is estimated based on a combustion state of the fuel injected into at least one cylinder of the engine. The fuel injectors are controlled so that a specific amount of fuel is injected into the at least one cylinder and an amount of fuel corresponding to an operating condition of the engine is injected into cylinders other than the at least one cylinder. An additional fuel injection is performed after the fuel injection of the specific amount with respect to the at least one cylinder, for example, when a torque difference parameter indicative of a difference between a torque generated by the at least one cylinder and a torque generated by the other cylinders is equal to or greater than a predetermined threshold value.

摘要： A control system for an internal combustion engine having fuel injection valves provided in a combustion chamber and an exhaust gas recirculation mechanism. Target maximum cylinder pressure change rates are set according to the operating condition of the engine. The maximum change rate of the detected cylinder pressure and a fuel injection timing correction amount are calculated wherein a difference between the calculated maximum change rate and the target maximum cylinder pressure change rate decreases. The fuel injection timing is corrected with the fuel injection timing correction amount. The recirculation amount of exhaust gases is controlled using the calculated control value. A correction amount of the exhaust gas recirculation amount is calculated when the fuel injection timing correction amount exceeds a predetermined amount. The exhaust gas recirculation amount is controlled using the control value corrected with the correction amount of the exhaust gas recirculating amount.

摘要： A control system used with an engine determines a fuel injection timing according to a detected engine operating condition and fuel injection is executed through a fuel injection valve. The target ignition timings of the fuel are set according to the detected engine operating condition and stored in a memory. An ignition delay of the actual ignition timing relative to the target ignition timing and a cetane number of the fuel are calculated. Control values of the recirculation amount of exhaust gases are set according to the detected engine operating condition and stored in the memory. The stored control value is retrieved and the recirculation amount of exhaust gases is controlled using the retrieved control value. A correction amount of the recirculation amount of exhaust gases is calculated according to the estimated cetane number and the recirculation amount of exhaust gases is controlled using the corrected control value.
