Publication number: 20180073460Abstract: A control system for an internal combustion engine, which is capable of controlling fuel injection valves while causing valve-closing delay time periods, which occur with the valves actually mounted on the engine, to be reflected thereon, thereby making it possible to improve exhaust emission characteristics and fuel economy performance. The ECU of the control system performs initial value-specific control in fuel injection control and ignition timing control, such that initial value acquisition conditions are satisfied, so as to calculate the initial values of the valve-closing delay time periods when the initial value acquisition conditions are satisfied. When normal-time control is performed, the valve-opening time periods of the valves are calculated using the initial values of the valve-opening time periods, and the valves are controlled to be open over the valve-opening time periods.Type: ApplicationFiled: September 7, 2017Publication date: March 15, 2018Applicant: HONDA MOTOR CO., LTD.Inventors: Tatsuo Yamanaka, Susumu Nakajima, Naoki Yokoyama, Kenji Hirose, Hidekazu Hironobu, Seiichi Hosogai

Patent number: 9643435Abstract: A plate spring is disposed at an outer lateral face of each of a pair of supporting members which a separation mechanism includes. In separation ejection, when an opening and closing cover is closed while pressing parts of an opening and closing cover is in contact with plate springs of the separation mechanism, the separation mechanism is fixed at the separation ejection position and the nip roller of the separation mechanism is biased toward the platen roller because of the effect of the plate springs. Since the plate springs can be pressed by the pressing parts of the opening and closing cover, a component to press the plate springs can be eliminated.Type: GrantFiled: April 8, 2015Date of Patent: May 9, 2017Assignee: SATO HOLDINGS KABUSHIKI KAISHAInventor: Kenji Hirose
