An internal combustion engine which includes a valve deactivation mechanism for reducing an output power shock upon changing of the cylinder number. In an internal combustion engine which includes a valve deactivation mechanism driven by a slide pin which is driven by hydraulic pressure, response delay time after a signal is sent to oil control valves until an intake valve and an exhaust valve are activated or deactivated is used to form a control map in response to control parameters, and the valve deactivation mechanism is controlled based on the control map.

Internal combustion engine including valve deactivation mechanism

An engineprovided with a fuel injection mechanism (a fuel injection systemand an FI control unit) that supplies fuel of arbitrary quantity into a combustion chamberand a variable valve mechanism (an intake valve, an exhaust valve, hydraulic electromagnetic valve drive unitsand a valve event control unit) that varies the ratio of burned gas and air-fuel mixture in the combustion chamberfor combusting fuel by compression self ignition, is controlled so that a deviation &#x394;T between combustion initiation temperature and peak temperature after combustion in the combustion chamberis converged in a predetermined range.
