摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of suitably suppressing lean state of the air-fuel ratio immediately after the start of the catalyst warming control. SOLUTION: The catalyst warming control for promoting the warming of the exhaust emission control catalyst is performed by increasing the ISC opening so as to increase the air intake at the time t0 when the condition of execution of the catalyst warming control is established, and changing the combustion mode from the homogeneous combustion to the stratified charge combustion at the subsequent time t1. In order to suppress the lean state of the air-fuel ratio generated by the abrupt increase of the intake load factor according to the increase of the previous ISC opening, the entrance addition coefficient kst to be multiplied by the base injection is set to be the value α larger than [1] during the period from the time t0 when the condition of execution is established to the time t1 for changing the combustion mode, and the additioning correction of the fuel injection is performed.

摘要： PROBLEM TO BE SOLVED: To highly accurately control fuel pressure in a cylinder injection stopping period and at cylinder injection starting time thereafter, in an internal combustion engine having an injector for cylinder injection and an injector for intake passage injection. SOLUTION: A high pressure fuel pump 200 delivers quantity corresponding to a valve closing period of a solenoid spindle valve 250 by increasing pressure of fuel.

摘要： PROBLEM TO BE SOLVED: To control the valve operation timing with excellent controllability in any operating condition of an engine in a valve timing control device for an internal combustion engine. SOLUTION: In a valve timing adjustment system comprising a valve timing adjustment mechanism 25, an oil control valve 55, etc., provided on a timing pulley 12, the phase shift velocity of a cam shaft 12 is usually dispersed even when the same duty is given to the oil control valve 55 from an electronic control device 80. The control duty to the oil control valve 55 is set in the electronic control device 80 so that the actual valve timing agrees with the target valve timing, the actual phase shift velocity of the cam shaft 12 is operated, and the control duty set in the above procedure is corrected so as to be brought close to the prescriptive value on the phase shift velocity.
