    • In one embodiment, with respect to a common rail diesel engine to which an EGR apparatus and a variable capacity turbocharger has been applied, for each EGR ratio, as an intake filling efficiency that is set by the nozzle vane opening degree of a variable nozzle vane mechanism, adapted values that approximately maximize an intake charging efficiency are acquired by an automatic adaptation apparatus and a filling efficiency setting map is stored in a ROM, and the nozzle vane opening degree of the variable nozzle vane mechanism is controlled according to the filling efficiency setting map. The automatic adaptation apparatus, in a state with the nozzle vane opening degree fixed, obtains an EGR ratio where maximum torque is obtained while changing the EGR ratio, and acquires the nozzle vane opening degree at this time as an adapted value that corresponds to the present EGR ratio.

    • 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.
    • 本发明的内燃机的燃料喷射控制装置对共轨柴油发动机进行控制,使得在活塞到达压缩上止点的时刻,由于在前期喷射的燃料的燃烧引起的发热量 注射基本上是最大的,此外,使得在该时刻附近开始在主喷射中喷射的燃料的燃烧。 结果,通过充分利用由于预喷射引起的发热量,开始主喷射喷射的燃料的燃烧。 此外,这避免了产生反向扭矩,并且确保最大化在主喷射中喷射的燃料的燃烧产生的扭矩的量。

    • In one embodiment, with respect to a common rail diesel engine to which a variable capacity turbocharger has been applied, for each engine operating state, as a nozzle vane opening degree of a variable nozzle vane mechanism, an adapted value that approximately maximizes an intake charging efficiency is acquired with an automatic adaptation apparatus, a filling efficiency setting map is stored in a ROM, and the nozzle vane opening degree of the variable nozzle vane mechanism is controlled according to the filling efficiency setting map. The automatic adaptation apparatus automatically acquires, for each of a plurality of engine operating states, as an adapted value, the nozzle vane opening degree at the point in time that the intake charging efficiency becomes approximately maximum by changing the nozzle vane opening degree in a state with an amount of fuel injection, a fuel injection pattern, and a fuel injection pressure fixed.
