Patent number: 10329962Abstract: At crank angle CA10 at which the switch request of the drive cam was issued, the ejection operations of the pins at all the solenoid actuators started simultaneously. The ejected pins are seated on the cam carriers at crank angle CA12. The pin seated on the cam carrier moves along the grooves in accordance with the rotation of the cam carrier. The earliest finish timing of the switch operation of the drive cam is at crank angle CA13 (#4 cylinder). At the crank angle CA13, drive of the fuel injector and the ignition device in each cylinder is permitted.Type: GrantFiled: January 23, 2018Date of Patent: June 25, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takayoshi Kawai, Noriyasu Adachi, Shigehiro Sugihira, Keisuke Sasaki, Kaoru Otsuka, Shinji Sadakane, Hiroyuki Sugihara

Patent number: 10294835Abstract: When a stop request to the engine is issued, it is determined whether or not all of the drive cams are large cams. When it is determined that at least one of the small cams is included in the drive cams, the engine is continued to drive for a while and a switch control for switching the drive cams from the small cams to the large cams is executed within the duration. A self-holding type solenoid is used to switch between the small cams and the large cams. In the switch control, a permission to stop the engine is output at a timing when the “pin protrudable section” of the final cylinder #2 has elapsed.Type: GrantFiled: November 13, 2017Date of Patent: May 21, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kaoru Ohtsuka, Hiroyuki Sugihara, Shinji Sadakane, Noriyasu Adachi, Shigehiro Sugihara, Keisuke Sasaki, Takayoshi Kawai

Publication number: 20180230869Abstract: In a system that selects a large-cam as a driving cam at a time of a start of an engine, when an engine stop request is output, it is determined whether there is a small-cam cylinder for which a small-cam is selected as the driving cam. In a case where it is determined that there is a small-cam cylinder, a switching command for switching the driving cam from the small-cam to the large-cam is output. When an engine start request is output, the above determination is performed again. In a case where it is determined that there is a small-cam cylinder, the switching command is output to all solenoid actuators again. In addition, the drive of the fuel injector is suspended until the switching operation of the driving cam is completed for all cylinders.Type: ApplicationFiled: February 5, 2018Publication date: August 16, 2018Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigehiro SUGIHIRA, Noriyasu ADACHI, Keisuke SASAKI, Takayoshi KAWAI, Kaoru OTSUKA, Shinji SADAKANE, Hiroyuki SUGIHARA

Patent number: 10030596Abstract: In starting the engine, if it is determined that large cams are not completely prepared for all driving cams, valve closing timings of all intake valves are changed by driving the VVT so that all of the cylinders have equal in-cylinder filling efficiency. A fuel injection amount of each cylinder is determined by a feedforward control assuming that the large cams are completely prepared for all of the driving cams. When the valve closing timing of all of the intake valves are changed by driving the VVT to equalize the in-cylinder filling efficiencies of all of the cylinders, all of the cylinders have substantially equal in-cylinder air-fuel ratios.Type: GrantFiled: October 16, 2017Date of Patent: July 24, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroyuki Sugihara, Kaoru Otsuka, Shinji Sadakane, Noriyasu Adachi, Shigehiro Sugihira, Keisuke Sasaki, Takayoshi Kawai
