Patent number: 6976892Abstract: A water-cooled vertical engine is provided with an exhaust guide cooling water jacket and an exhaust manifold cooling water jacket formed in an engine compartment exhaust passage, a cylinder block cooling water jacket formed in a cylinder block, and a cylinder head cooling water jacket formed in a cylinder head. A first cooling path for supplying cooling water from a cooling water pump to the cylinder block cooling water jacket via the exhaust guide cooling water jacket and the exhaust manifold cooling water jacket is substantially independent from a second cooling path for supplying cooling water from the cooling water pump to the cylinder head cooling water jacket. Thermostats are provided in the cylinder block cooling water jacket and the cylinder head cooling water jacket, respectively.Type: GrantFiled: October 1, 2003Date of Patent: December 20, 2005Assignee: Honda Motor Co., Ltd.Inventors: Hiroki Tawa, Hideyuki Ushiyama, Tatsuya Kuroda

Patent number: 6913500Abstract: An outboard motor is provided with an engine compartment exhaust passage that is formed by joining via a joining part an exhaust manifold connected to a cylinder head and an exhaust guide connected to an exhaust passage of a mount case. By bending the portion of the exhaust manifold that is lower than the lowest combustion chamber so as to be farther away from the cylinder head than other portions of the exhaust manifold, the space in which the exhaust manifold is arranged can be minimized, and the joining part can be prevented from interfering with the cylinder head while minimizing any influence on the exhaust efficiency.Type: GrantFiled: October 2, 2003Date of Patent: July 5, 2005Assignee: Honda Motor Co., Ltd.Inventors: Hiroki Tawa, Tatsuya Kuroda

Patent number: 6890228Abstract: An outboard motor equipped with a water-cooled engine includes an exhaust manifold cooling water jacket for cooling an exhaust manifold for discharging to the outside exhaust gas from a combustion chamber, the exhaust manifold cooling water jacket being supplied with cooling water from a cooling water pump. A water outlet provided in the highest part of the exhaust manifold cooling water jacket is made to communicate with a water check outlet for confirming the circulation of cooling water due to operation of the cooling water pump. Thus, it is possible to reliably discharge air residing within the exhaust manifold cooling water jacket through the water check outlet. Since the water check outlet is used as an opening for discharging air, it is unnecessary to provide a special air outlet.Type: GrantFiled: October 1, 2003Date of Patent: May 10, 2005Assignee: Honda Motor Co., Ltd.Inventors: Hiroki Tawa, Tatsuya Kuroda

Patent number: 6647962Abstract: An outboard motor includes an internal combustion engine provided with a pair of intake valves. The opening and closing operation of one of the intake valves can be paused. The internal combustion engine comprises a vertical crankshaft, a cylinder head provided with an intake port having a pair of intake openings for one combustion chamber, and a fuel injection valve for injecting the fuel into the intake port. The intake port has an upper branch section and a lower branch section extended under the upper branch section. A valve train includes a valve-operation mode changing mechanism. The valve-operation mode changing mechanism pauses the opening and closing operation of the first intake valve and operates the second intake valve for opening and closing the lower intake opening of the lower branch section while the internal combustion engine is operating at engine speeds in a low-speed range.Type: GrantFiled: June 10, 2002Date of Patent: November 18, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Tatsuya Kuroda

Patent number: 6527604Abstract: A compact and lightweight outboard engine (1) mounted to a boat stern by a mounting device having a tilt shaft comprises: an engine (2) including a flywheel (56) positioned at a lower end portion of a vertically extending crankshaft, and an oil pan positioned below the flywheel (56). An upper wall of a flywheel chamber (59) accommodating the flywheel 56 is made up of a bottom wall of a crank chamber made of a crankcase (30), etc., and a bottom wall (30a) of the crankcase (30) forming a front portion of the engine body (3) has a return oil path 71 formed forward of an inner circumferential wall surface (60e) of a circumferential wall (60) of the flywheel chamber (59) and having inflow openings (71a, 71b) through which lubricant oil flows from the crank chamber. Such outboard engine prevents output loss by preventing or minimizing lubricant oil staying in the crank chamber while the engine is driven in a tilt-up condition.Type: GrantFiled: February 13, 2002Date of Patent: March 4, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masanori Tsubouchi, Tatsuya Kuroda, Haruo Tsusaka, Masaki Tsunoda
