Patent number: 11008975Abstract: An internal combustion engine includes a crankshaft that has a journal linked to a bearing and is rotatably supported on the crankcase, a power transmission gear fixed to an extremity of the crankshaft that has a smaller diameter than a diameter of the journal and projects outward of the crankcase, a to-be-detected body that is fixed on an outer periphery of a collar member disposed between the bearing and the power transmission gear and is relatively non-rotatably supported on the crankshaft, and a detection sensor that is made to face a trajectory of the to-be-detected body and detects movement of the to-be-detected body to generate a pulse signal. This provides a structure for disposing a to-be-detected body that enables any increase in the dimensions of an internal combustion engine to be avoided.Type: GrantFiled: February 15, 2018Date of Patent: May 18, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Yukihiro Yasuda, Hiroyuki Uchida, Kazuya Tanabe, Takao Iwasaki, Takuya Warashina

Patent number: 10890137Abstract: An internal combustion engine includes a crankshaft that is rotatably supported on a crankcase via a pair of bearings and has a crank housed in a crank chamber, a to-be-detected body that is housed in the crank chamber and is supported on the crankshaft, and a detection sensor that is made to face a trajectory of the to-be-detected body and detects movement of the to-be-detected body to generate a pulse signal. The to-be-detected body is disposed on an inner side of the bearing. Thus, an internal combustion engine is provided that enables a crank angle to be detected in a state in which vibration and flexure occurring in a crankshaft are suppressed.Type: GrantFiled: March 15, 2018Date of Patent: January 12, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Takao Iwasaki, Yoshiyuki Ikebe, Kazuyuki Kosei, Takuya Warashina, Kazuya Tanabe, Hiroyuki Uchida

Patent number: 8453559Abstract: A piston with transverse-rib through holes formed easily therein for reducing the cost of manufacturing. A piston includes a pair of mutually opposed longitudinal ribs individually formed with piston pin bosses interconnecting a pair of piston skirt portions on a back side of a piston head. A pair of transverse ribs interconnect the mutually opposed longitudinal ribs with the transverse ribs. The pair of transverse ribs are formed with transverse-rib through holes at places proximal to the back side of the piston head. A skirt opening is formed by cutting away a part of the piston skirt portion that is opposed to the transverse rib and faces the transverse-rib through hole.Type: GrantFiled: November 10, 2009Date of Patent: June 4, 2013Assignee: Honda Motor Co., Ltd.Inventors: Kenichi Ohmori, Kazuyuki Nakai, Akifumi Nomura, Kazuya Tanabe, Satoshi Ino, Shinichi Wagatsuma

Patent number: 8358910Abstract: An information signal is received, which includes a main information content signal carrying the contents of the information, a CM portion signal carrying commercial messages (CM) and an information mode discriminating signal used for discriminating information modes of the main information content signal and the CM signal from each other according to the contents. A video signal is encoded per plurality of several video frames, the video signal including the main information content signal and the CM portion signal. The encoded video signal is recorded in a storage medium. The video signal is reproduced, during the recording, from the storage medium while the CM portion signal is skipped. The received main information content signal and CM portion signal are recorded in the storage medium. The information mode discriminating signal is recorded in the storage medium or another temporary storage medium.Type: GrantFiled: May 30, 2007Date of Patent: January 22, 2013Assignee: JVC Kenwood CorporationInventors: Daisaku Kato, Kazuya Tanabe

Patent number: 7472685Abstract: An internal combustion engine includes a throttle controlling mechanism; a valve characteristic varying mechanism which controls an internal EGR rate by the control of an overlap period Pa and a non-overlap period Pb; and an output setting means which sets a required amount of engine output. The throttle controlling mechanism controls an opening degree of a throttle valve to fully open the throttle valve at a predetermined load Da with an increase in an operating amount D in a first load range Fa which covers load range below the predetermined load Da in a low-load range, and to keeps the throttle valve fully opened in a second load range Fb which covers a load range over the predetermined load Da. The valve characteristic varying mechanism controls the engine output by controlling the overlap period Pa or the non-overlap period Pb according to the required amount D over the entire load range, and controls valve operation characteristics to obtain a maximum internal EGR rate at the predetermined load Da.Type: GrantFiled: January 20, 2005Date of Patent: January 6, 2009Assignee: Honda Motor Co., Ltd.Inventors: Kazuya Tanabe, Takashi Tsutsumizaki, Yutaka Inomoto, Kosuke Tsunashima

Patent number: 6990938Abstract: A valve operating device for an internal combustion engine is capable of increasing a negative valve overlapping duration when maximum lift amounts of an intake valve and an exhaust valve are small. The valve operating device is provided with intake-side and exhaust-side characteristic adjustment mechanisms for adjusting operating characteristics of an intake valve and an exhaust valve. Each characteristic adjustment mechanism has a control cam rotating integrally with a cam shaft, an electric motor that causes a holder pivoted on the cam shaft to rotate about the cam shaft, a sub-rocker lever pivoted on the holder and caused to oscillate by the control cam, and a valve cam that is caused to oscillate around the cam shaft by oscillation of the holder and the sub-rocker lever, for causing oscillation of main rocker levers.Type: GrantFiled: August 29, 2003Date of Patent: January 31, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yutaka Inomoto, Masahiro Kuroki, Takashi Tsutsumizaki, Kazuya Tanabe
