    • PROBLEM TO BE SOLVED: To reduce an HC emission amount while securing combustion stability at the time of start or cold start (before completion of engine warm-up) of a cylinder injection type internal combustion engine.
      SOLUTION: At the time of start or cold start of the cylinder injection type internal combustion engine, an exhaust valve early closing control in which the close timing of an exhaust valve is controlled before an intake top dead center is conducted to compress a residual exhaust gas in a cylinder by rising of a piston from a close timing of the exhaust valve to the intake top dead center, and thereby increasing a temperature of the inside-cylinder gas with heat of the compression. At the time from the closing timing of the exhaust valve to the intake top dead center, a pre fuel injection is performed to combust the injected fuel of the pre fuel injection, and thereby further increasing the inside-cylinder temperature. According to the increasing effect of the inside-cylinder temperature by the early closing control of the exhaust valve and the pre fuel injection, vaporization of injected fuel of a main fuel injection after the pre fuel injection is effectively stimulated to secure the combustion stability and effectively reduce a wet amount, and thereby reducing the HC emission amount at the time of start or cold start.

    • PROBLEM TO BE SOLVED: To surely change a valve open/close characteristics of a variable valve control mechanism to a state suitable for starting, without delay in stop timing of an engine, in emergency stop of an engine when a driver continues operating an operation part of a push start switch for an emergency stop determination time or more.
      SOLUTION: At a time t1 of pushing operation of the push start switch, a count of an operation time of the push start switch is started. Then, at a time t2 where the operation time of the push start switch exceeds a predetermined time T2 set to be shorter than the emergency stop determination time T1, an emergency stop time VCT control execution flag is switched ON to start an emergency stop time VCT control, so that actual valve timing is controlled to be changed to optimal valve timing in start. At a time t3 where the operation time of the push start switch exceeds the emergency stop determination time T1, the ignition switch is turned off to perform emergency stop of the engine.

    • PROBLEM TO BE SOLVED: To effectively reduce a hydrocarbon discharge quantity of an engine. SOLUTION: On starting the engine or immediately after starting the engine, when it is not yet in an intake pipe pressure drop state (a state in which the intake pipe pressure is lower than a predetermined pressure α), as a retraction effect of unburnt hydrocarbon due to descent of a piston after a top dead center is little, an unburnt hydrocarbon discharge quantity is decreased by trapping the unburnt hydrocarbon in a cylinder by executing an exhaust valve early closing control for advancing an angle of an exhaust valve timing and controlling a closing timing of the exhaust valve to be prior to the top dead center. Then, when the intake pipe pressure drops to be lower than the predetermined pressure α bringing about the intake pipe pressure lowering state, the retraction effect of the unburnt hydrocarbon increases due to descent of the piston after the top dead center and the unburnt hydrocarbon once discharged from the cylinder in an exhaust process is effectively retracted by descent of the piston after top dead center as an exhaust valve late closing control for controlling the closing timing of the exhaust valve after the top dead center is executed by delaying an angle of the exhaust valve timing.

    • PROBLEM TO BE SOLVED: To achieve reliable knock determination higher than conventional one by using an original knock determining method which does not conventionally exist.
      SOLUTION: In knock determination, the waveform of a signal (the waveform of detected knock) passing through a band pass filter 17 of a knock sensor 16 is compared with an ideal knock waveform and the correlation between both of these is evaluated. The ideal knock waveform is calculated in consideration of a factor depending on a crank angle (a term depending on the crank angle), a factor depending on an actual time (a term depending on the actual time) and a factor depending on an engine structure (a vibration transmission function). For the factor depending on the actual time (the term depending on the actual time), energy loss in a combustion chamber and a time constant of the band pass filter 17 are considered. For the factor depending on the engine structure (the vibration transmission function), the influence of a vibration transmission system is taken into consideration during a time since knock vibration generated in a cylinder is transmitted to a cylinder block until it is detected by the knock sensor 16.
