Patent number: 8899202Abstract: A fuel injection device comprising electricity-generating means generating electricity by rotation of an engine and outputting a predetermined signal, and a solenoid valve injecting fuel; the valve being opened as a result of a drive current applied to a coil, and the fuel being injected into an intake passage of the engine at a predetermined timing during the rotation of the engine; to ensure that the flow rate required during high-speed operation can be adequately provided in a fuel injection device for injecting/supplying fuel to an engine. The electricity-generating means is an alternating current generation means attached to the engine in a crank angle position at which an output is generated in synchronization with the intake timing of the engine; the signal is an injection command signal applied to the solenoid valve as an alternating-current drive current; and the applied voltage increases with increased engine speed.Type: GrantFiled: February 10, 2011Date of Patent: December 2, 2014Assignee: Zama Japan Kabushiki KaishaInventors: Takumi Nonaka, Hideki Watanabe

Patent number: 8857188Abstract: A hybrid drive device including an electric motor; an automatic transmission; a lubricating oil passage to which a lubricating oil pressure is supplied; and a switching valve that is switched between a first state where the lubricating oil passage communicates with a first lubricating oil passage that guides lubricating oil to the automatic transmission, and a second state where the lubricating oil passage communicates with a second lubricating oil passage that guides the lubricating oil to the electric motor. The electric motor and an internal combustion engine output shaft are operable in conjunction with the automatic transmission. The switching valve is switched from the first state to the second state when a vehicle is in a stationary state or running at a speed of a predetermined value or less including the stationary state of the vehicle.Type: GrantFiled: March 1, 2012Date of Patent: October 14, 2014Assignee: Aisin AW Co., Ltd.Inventors: Kazuyuki Noda, Masashi Kito, Yuichi Seki, Satoru Kasuya

Patent number: 8146558Abstract: An engine starting assist system configured to be used on an internal combustion engine. The engine starting assist system includes a battery, a choke valve disposed in an air intake of an air/fuel-mixing device, the choke valve having an open position and a closed position, a rotary solenoid powered by the battery, the rotary solenoid having an output shaft, and a bimetal coil. The output shaft of the rotary solenoid is coaxial with the bimetal coil.Type: GrantFiled: August 13, 2008Date of Patent: April 3, 2012Assignee: Briggs & Stratton CorporationInventors: Max W. Clouse, Thomas G. Guntly, Mel O. Lux, Michael B. Busateri

Patent number: 8055434Abstract: A fuel injection control system for a motorcycle includes an ECU (Engine Control Unit) which calculates the amount of fuel to be injected by an injector based on data detected by various sensors. The fuel injection control system also includes a generator which supplies electric power to the injector and the ECU, and is driven in accordance with the engine, and a kick pedal for manually starting the engine by manually driving the generator with a user's foot. The ECU is configured to acquire data detected by the sensors at shorter intervals during a predetermined period before starting the engine than after the engine is started.Type: GrantFiled: January 30, 2009Date of Patent: November 8, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Yuichi Sasaki

Patent number: 7004134Abstract: A positioning pin is knocked onto a crankshaft of an engine and a key way is formed in a boss of a first flywheel. When an outer rotor type generator is connected with the engine, the boss of the first flywheel is fitted over the crankshaft so as to adjust the positioning pin to the key way. When an inner rotor type generator is connected with the engine, a rotor shaft on which a rotor of a generator is mounted is fitted to a second flywheel so as to adjust the positioning pin to a key way formed in the second flywheel. The ignition angle of the engine is determined by fitting the positioning pin to the key way.Type: GrantFiled: February 12, 2004Date of Patent: February 28, 2006Assignee: Fuji Jukogyo Kabushiki KaishaInventor: Masaaki Higuchi

Patent number: 6336434Abstract: An engine unit of an outboard motor comprises an engine body, a crank case in which a crankshaft is vertically perpendicularly arranged in a usable mounted state of the outboard motor, a cylinder block which is disposed to a rear side of the crank case and in which cylinders are arranged, a cylinder head disposed to a rear side of the cylinder block, a magnet device mounted to a top end portion of the crankshaft projecting upward and comprising a stator and a flywheel to which a rotor is integrally formed. In the engine unit, the crankshaft is supported by a bearing boss disposed to a mating portion of the cylinder block and the crank case through a bearing means and an oil seal is disposed between the bearing boss and the bearing means, and the magnet device is mounted to the engine body through the stator through a mounting portion. A diameter of the mounting portion of the stator is to be larger than an outer diameter of the oil seal.Type: GrantFiled: May 18, 2000Date of Patent: January 8, 2002Assignee: Suzuki Kabushiki KaishaInventors: Nobuyuki Shomura, Yukihiro Yoshikawa, Kazuo Mineno, Takeshi Toyama
