Patent number: 11143085Abstract: A cooling structure of an internal combustion engine includes a thermostat provided to switch circulation between a radiator passage and a bypass passage in an engine body, to thereby enable acceleration of early warming up via the bypass passage without impairing the external appearance or increasing the size of the internal combustion engine. The cooling structure also includes an in-cylinder-block fluid passage partitioned up and down in an axial direction of a cylinder axis into an in-cylinder-block upper fluid passage and an in-cylinder-block lower fluid passage by a partition wall. The bypass passage is partially composed of the in-cylinder-bock lower fluid passage.Type: GrantFiled: July 26, 2019Date of Patent: October 12, 2021Assignee: Honda Motor Co., Ltd.Inventors: Kensuke Mori, Hiroyuki Tsukagoshi, Koichiro Matsushita, Reina Kurosu

Patent number: 10378420Abstract: Provided is a saddle-ride type vehicle that can improve the cooling ability when a radiator fan is provided only on one radiator of right and left radiators. A saddle-ride type vehicle has a water-cooled engine, right and left radiators supported by a body frame, and a cooling water passage that connects the right and left radiators and the water-cooled engine. A radiator fan is provided only on one radiator of the right and left radiators. One cooling water passage that connects the one radiator and the water-cooled engine has a larger diameter than the other cooling water passage that connects the other radiator and the water-cooled engine. The one radiator is larger than the other radiator.Type: GrantFiled: October 11, 2017Date of Patent: August 13, 2019Assignee: Honda Motor Co., Ltd.Inventors: Toru Kisaichi, Hiroyuki Kaga, Koichiro Matsushita

Patent number: 10323565Abstract: In an internal combustion engine, a thermostat valve for changing over between coolant circulation through a radiator-routing passage to coolant circulation through a bypass passage, is provided with a first valve for opening and closing the radiator-routing passage, and a second valve for opening and closing the bypass passage. The first and second valves and are operable concurrently. A cylinder coolant jacket around cylinder bores of a cylinder portion is partitioned into two in a cylinder axis direction to thereby form a main cylinder coolant jacket on a side of a cylinder head portion and a sub-cylinder coolant jacket on a side of a crankcase portion. The bypass passage is formed partly by the sub-cylinder coolant jacket. The above arrangement expedites warming-up during the engine start and achieves favorable appearance by a simplified structure.Type: GrantFiled: January 9, 2018Date of Patent: June 18, 2019Assignee: HONDA MOTOR CO., LTD.Inventor: Koichiro Matsushita
