Patent number: 7686122Abstract: An exhaust system for a saddle-ride type vehicle provides sufficient volume in a chamber while avoiding interference between the chamber and other parts. The vehicle center of gravity is lowered and differences in exhaust pipe length are reduced. Exhaust pipes are connected to combustion chambers of front and rear cylinder banks of a V-type engine. A chamber is connected to the exhaust pipes and mufflers are connected to the chamber. The chamber has an exhaust pipe connection wall to which the exhaust pipes are connected and opposing muffler connection walls. The mufflers are connected to positions on the muffler connection walls closer to the engine relative to a center in a longitudinal direction of the vehicle.Type: GrantFiled: August 1, 2006Date of Patent: March 30, 2010Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Yoshiharu Nakayama

Patent number: 7506627Abstract: An engine includes a balancer shaft that is supported at its both ends through bearings disposed within an engine crankcase. The balancer shaft lies generally parallel with a crankshaft and includes balancer weights, which are provided generally at the ends of the balancer shaft. At least one of the balancer weights is made up of first and second weight portions. The first and second weight portions are disposed on opposite sides of the corresponding bearing. In this manner, the bending moment on the shaft is reduced and, consequently, the balancer shaft can have a smaller diameter to reduce the size of the crankcase.Type: GrantFiled: August 17, 2005Date of Patent: March 24, 2009Assignee: Yamaha Motor Co., Ltd.Inventor: Yoshiharu Nakayama

Patent number: 7219637Abstract: An engine includes a variable valve timing device coupled to a camshaft, which operates within a cam chamber of the engine. The variable valve timing device includes a hydraulic pressure switchover valve having an elongated valve body. The switchover valve is disposed outside the cam chamber and is oriented such that a longitudinal axis of the elongated valve body lies generally parallel to a rotational axis of the camshaft. In this manner, the engine size can generally remain compact while still employing a variable valve timing device with a switchover valve.Type: GrantFiled: September 14, 2005Date of Patent: May 22, 2007Assignee: Yamaha Motor Co., Ltd.Inventor: Yoshiharu Nakayama

Publication number: 20060037311Abstract: A chain chamber of an engine, which accommodates a cam chain for driving a camshaft, is formed between a first cylinder and a second cylinder aligned in the direction along the camshaft. A first-cylinder valve chamber and a second-cylinder valve chamber each accommodate a corresponding valve for supplying secondary air to an exhaust system. The first and second chambers overlap the chain chamber and lie adjacent to each other above the chain chamber. The first-cylinder and second-cylinder valve chambers have first and second valve chamber openings, respectively. A first and a second valve chamber cover for opening and closing the respective valve chamber openings are integrally formed together. This construction reduces the number of engine parts associated with a secondary air system and simplifies the sealing structure of secondary air introduction hoses and cover members.Type: ApplicationFiled: August 17, 2005Publication date: February 23, 2006Inventor: Yoshiharu Nakayama
