Publication number: 20120247410Abstract: A water-cooled V-type engine includes a first coolant passage for supplying a liquid coolant discharged from a water pump disposed proximate a first cylinder, to a water jacket of the first cylinder. The engine also includes a second coolant passage which is branched off from the first coolant passage, and which is provided for supplying coolant to a water jacket of a second cylinder. The engine design allows for a shortened coolant hose. The water pump may include an integral fluid conduit including a branching portion where said second coolant supply passage is branched from said first coolant supply passage, and a restricted portion proximate the branching portion. A motorcycle including a vehicle body frame is also described, where the water-cooled V-type engine is operatively attached to the vehicle body frame.Type: ApplicationFiled: March 28, 2012Publication date: October 4, 2012Applicant: HONDA MOTOR CO., LTD.Inventors: Hodaka MUKOUHARA, Hiroyuki SUGIURA, Yohei MAKUTA

Patent number: 7694657Abstract: In an engine for a motorcycle, a main shaft is supported rotatably by first and second support walls of a lower case which constitutes a part of a crank case. The center distance between the crank shaft and the main shaft is to be shortened while attaining a reduction in the number of parts and the number of assembling steps. A first bearing hole is formed in a first support wall for fitting therein and holding a first bearing which is mounted on one end of the main shaft. A second bearing hole is formed in a second support wall which permits the main shaft to be inserted therein from an opposite end side of the main shaft until one end of the main shaft is fitted in the first bearing. A second bearing is fitted and held in the second bearing hole so as to be fitted on the main shaft from the opposite end side of the main shaft after fitting of one end of the main shaft into the first bearing.Type: GrantFiled: January 13, 2006Date of Patent: April 13, 2010Assignee: Honda Motor Co., Ltd.Inventors: Toru Gunji, Hiroyuki Sugiura

Patent number: 7610139Abstract: An in-cylinder pressure detection device for an internal combustion engine, which is capable of detecting an in-cylinder pressure accurately without being adversely affected by changes in the atmospheric pressure even when the atmospheric pressure changes. An in-cylinder pressure sensor detects pressure within a cylinder as a detected in-cylinder pressure. An ECU estimates pressure generated in the cylinder during a non-combustion period as a motoring pressure. An atmospheric pressure sensor detects an atmospheric pressure (PA). The ECU corrects the motoring pressure according to the atmospheric pressure and identifies correction parameters such that the difference between the detected in-cylinder pressure detected during a compression stroke of the engine and the corrected motoring pressure becomes minimum, and corrects the detected in-cylinder pressure by the identified correction parameters, to thereby calculate an in-cylinder pressure.Type: GrantFiled: August 29, 2007Date of Patent: October 27, 2009Assignee: Honda Motor Co., Ltd.Inventors: Takahide Mizuno, Shusuke Akazaki, Hiroyuki Sugiura, Mitsuo Hashizume

Patent number: 7606650Abstract: An in-cylinder pressure detection device for an internal combustion engine, which is capable of calculating a hysteresis amount properly to thereby detect in-cylinder pressure with high accuracy. The in-cylinder pressure detection device comprises an in-cylinder pressure sensor that detects in-cylinder pressure as a detected in-cylinder pressure. The in-cylinder pressure detection device estimates an in-cylinder pressure generated when combustion is not performed in the cylinder, as a motoring pressure, calculates a hysteresis amount indicative of a difference between the detected in-cylinder pressure and an actual in-cylinder pressure, based on the detected in-cylinder pressure and the motoring pressure obtained during the exhaust stroke of the engine, and corrects the detected in-cylinder pressure based on the calculated hysteresis amount.Type: GrantFiled: May 9, 2007Date of Patent: October 20, 2009Assignee: Honda Motor Co., Ltd.Inventors: Takahide Mizuno, Shusuke Akazaki, Hiroyuki Sugiura, Yuji Yamamoto, Mitsuo Hashizume, Kentaro Onuma
