  • Internal combustion engine including valve deactivation mechanism
    Patent number: 8794213
    Abstract: 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.
    Type: Grant
    Filed: March 28, 2011
    Date of Patent: August 5, 2014
    Assignee: Honda Motor Co., Ltd.
    Inventors: Hayato Maehara, Shunsuke Kitawaki, Shinji Saito, Yukihiro Asada

  • Control method of compression self ignition internal combustion engine
    Patent number: 7628145
    Abstract: An engine 1 provided with a fuel injection mechanism (a fuel injection system 18 and an FI control unit 41) that supplies fuel of arbitrary quantity into a combustion chamber 9 and a variable valve mechanism (an intake valve 14, an exhaust valve 15, hydraulic electromagnetic valve drive units 16, 17 and a valve event control unit 40) that varies the ratio of burned gas and air-fuel mixture in the combustion chamber 9 for combusting fuel by compression self ignition, is controlled so that a deviation ?T between combustion initiation temperature and peak temperature after combustion in the combustion chamber 9 is converged in a predetermined range.
