    • An apparatus for controlling an internal combustion engine that can estimate a quantity of heat generated is provided.An arithmetic processing unit 20 can calculate PVκ variable according to a crank angle θ and dPVκ/dθ as a rate of change in PVκ. For convenience' sake, a “crank angle at which dPVκ/dθ is a maximum while PVκ is increasing” is to mean a “crank angle at a combustion proportion of 50%” and be referred to also as “θCA50”. PVκ calculated for θCA50 is to be referred to also as “PVκCA50”. In addition, for convenience' sake, a difference between PVκ (which is zero in the embodiment as shown in FIGS. 3 and 4) and PVκCA50 at a start of combustion is also referred to as ΔPVκCA50. A total quantity of heat generated Q is assumed to be twice as much as a value of ΔPVκCA50.

    • An object of this invention is to provide a control apparatus for an internal combustion engine which makes it possible to reliably avoid an abnormal increase in in-cylinder pressure due to pre-ignition. The control apparatus of this invention controls an internal combustion engine including an injector that directly injects fuel into a cylinder. The control apparatus includes pre-ignition detection means that executes an operation to detect pre-ignition until a time of a crank angle θA, and injection instruction means that, at a time of a crank angle θB that is before the crank angle θA, sends to the injector an injection instruction to perform fuel injection that suppresses pre-ignition combustion. Preferably, the control apparatus includes energization stopping means that, when the pre-ignition detection means does not detect pre-ignition until the time of the crank angle θA, stops energization of the injector that is started by the injection instruction.
    • 本发明的目的是提供一种用于内燃机的控制装置,其可以可靠地避免由于预点火引起的缸内压力的异常增加。 本发明的控制装置控制包括将燃料直接喷射到气缸中的喷射器的内燃机。 控制装置包括预先点火检测装置,其执行检测预火点直到曲柄角度θA的时间的操作,而喷射指令意味着在曲柄角度θA之前的曲柄角θB时间发送 向喷射器施加喷射指令以进行燃料喷射以抑制点火前燃烧。 优选地,控制装置包括通电停止装置,当预燃点检测装置在曲轴角度θA之前未检测到点火时,停止由喷射指令开始的喷射器的通电。
