Patent number: 11401878Abstract: A fuel injection control apparatus including a microprocessor. The microprocessor is configured to perform calculating a target injection time, determining a first crank angle defining a start of fuel injection and a second crank angle defining an end of fuel injection, controlling a fuel injector in an injection start priority mode in which the fuel is injected for the first target injection time from a first time point corresponding to the first crank angle or an injection end priority mode in which the fuel is injected for the second target injection time from a second time point corresponding to a target crank angle, and the controlling including controlling the fuel injector so as to inject the fuel in the injection start priority mode or the injection end priority mode in accordance with an injection mode.Type: GrantFiled: March 29, 2021Date of Patent: August 2, 2022Assignee: Honda Motor Co., Ltd.Inventors: Masatoshi Nakajima, Hidekazu Hironobu, Daiki Yamazaki, Ryuichi Hata, Nobuaki Ito, Yasunori Shinmi

Patent number: 11306677Abstract: A fuel injection control apparatus including a microprocessor. The microprocessor is configured to perform calculating injection target values per a combustion cycle, controlling a fuel injector so as to inject fuel in accordance with the injection target values, instructing a switching between a first mode injecting the fuel and a second mode stopping the fuel injection, determining whether it is possible to inject the fuel in accordance with the injection target values when the switching from the second mode to the first mode is instructed, and modifying the injection target values by reducing a target injection frequency when it is determined to be impossible to inject the fuel in accordance with the injection target values, and the controlling including controlling the fuel injector, when the injection target values are modified, so as to inject the fuel in accordance with modified injection target values.Type: GrantFiled: March 29, 2021Date of Patent: April 19, 2022Assignee: Honda Motor Co., Ltd.Inventors: Masatoshi Nakajima, Masahiro Takeuchi, Hidekazu Hironobu, Daiki Yamazaki, Nobuaki Ito, Ryuichi Hata, Yasunori Shinmi
