摘要： In one embodiment, a total fuel injection amount is calculated from a torque required by an engine. A division ratio of a pre-injection amount that achieves both suppression of ignition delay of fuel from a main injection and suppression of a peak value of a heat production ratio of combustion from the main injection is calculated. Upper and lower limit guards are given to the obtained divided amount, and the divided injection amount is calculated. The injection amount of the main injection is obtained by subtracting the divided injection amount from the total fuel injection amount.

摘要： A fuel injection control apparatus of an internal combustion engine of the present invention performs control for a common rail diesel engine so that at a timing when a piston reaches compression top dead center, the rate of heat production due to the combustion of fuel injected in pre-injection is substantially maximal, and furthermore so that the combustion of fuel injected in main injection is started in the vicinity of this timing. As a result, the combustion of fuel injected in main injection is started by fully utilizing the heat production amount due to the pre-injection. Also, this avoids the production of reverse torque, as well as ensures maximizing the amount of torque produced by the combustion of fuel injected in main injection.

摘要： In a diesel engine, an inside of a cylinder is divided into intra-cavity and extra-cavity regions. Ideal heat release rate waveform models, each formed of an isosceles triangle in which each oblique line gradient is a reaction rate, an area is a reaction amount and a base length is a reaction period with a reaction start temperature as a base point, are generated respectively for a vaporization reaction, low-temperature oxidation reaction, thermal decomposition reaction and high-temperature oxidation reaction of injected fuel for each region. An ideal heat release rate waveform of the reaction modes is generated by smoothing the ideal heat release rate waveform models through filtering and combining the ideal heat release rate waveforms, and is compared with an actual heat release rate waveform obtained from a detected in-cylinder pressure. A reaction mode having a deviation larger than or equal to a predetermined amount is diagnosed as being abnormal.
