Patent number: 9212605Abstract: A drive apparatus for a vehicle auxiliary device is provided that basically includes first and second drive sources, an auxiliary device, first, second and third rollers, first, second and third idler rollers and a roller pair selection mechanism. The first, second and third rollers are linked to rotary shafts of the first and second drive sources and the auxiliary device. The first, second and third idler rollers are disposed at gap positions formed between the first, second and third rollers. The roller pair selection mechanisms select a power-transmitting roller pair from among the first, second and third rollers by selectively moving the first, second and third idler rollers in roller contact directions, thereby interposing the first, second and third idler rollers therebetween.Type: GrantFiled: September 3, 2013Date of Patent: December 15, 2015Assignee: Nissan Motor Co., Ltd.Inventors: Shin Hashimoto, Kentarou Watanabe, Takeshi Yamamoto, Masaaki Kubo, Katsuhiko Sando, Ryusei Matsuoka

Patent number: 7771675Abstract: A reforming catalyst (6) induces an isomerization reforming reaction and a decomposition reforming reaction of a gasoline fuel. Injectors (27, 33, 35, 36) supply an isomerized fuel generated by the isomerization reforming reaction and a decomposed fuel generated by the decomposition reforming reaction respectively to the internal combustion engine (1). The ratio of the isomerization reforming reaction and the decomposition reforming reaction depends on a catalyst temperature, and can be altered arbitrarily by controlling an air supply amount to the catalyst (6) via an air amount regulating valve (14) and a fuel supply amount to the catalyst (6) via a fuel injector (8) and thereby controlling the catalyst temperature.Type: GrantFiled: February 21, 2007Date of Patent: August 10, 2010Assignees: Nissan Motor Co., Ltd.Inventors: Isamu Hotta, Masaaki Kubo, Eiji Takahashi, Koichi Ashida, Yasushi Sekine

Patent number: 7597068Abstract: A heat engine system includes a fuel reforming system for supplying a reformed gas to be combusted in an internal combustion engine or used to generate electricity in a fuel cell. An alcohol-containing fuel and water are mixed in a tank and separated into a hydrocarbon based fuel and the fluid mixture of alcohol and water. A reformer uses an endothermic reaction, such as a water vapor reforming process, to obtain the reformed gas from the fluid mixture.Type: GrantFiled: February 28, 2007Date of Patent: October 6, 2009Assignee: Nissan Motor Co., Ltd.Inventors: Kaori Arai, Masaaki Kubo

Patent number: 7204225Abstract: An internal combustion engine includes a main combustion chamber and a small auxiliary combustion chamber. The main chamber is formed by a cylinder, the undersurface of a cylinder head, and the crown of a piston. A main ignition unit is disposed in the cylinder head, including a main body and a spark plug. The auxiliary chamber is formed within the main ignition unit. The main and auxiliary chambers are connected via a communication passage. The piston crown includes a cavity. When a fuel injection valve sprays fuel into the cavity on compression stroke, a tumble flow of fuel gas is generated to locally form a relatively rich air-fuel mixture near the communication passage. The air-fuel mixture partly flows into the auxiliary chamber as the piston travels upwardly. The air-fuel mixture in the auxiliary chamber is ignited by the spark plug so that a combustion flame propagates into the main chamber.Type: GrantFiled: March 4, 2005Date of Patent: April 17, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Masaaki Kubo, Toru Noda, Isamu Hotta

Patent number: 7159543Abstract: An engine having a cylinder, a piston slideably received in the cylinder, a crankshaft connected to the piston, and a multi-link piston crank mechanism. The multi-link piston crank mechanism controls movement of the piston such that an acceleration of the piston at top dead center is less than an acceleration of the piston at bottom dead center. A determining device determines an operating condition of the engine. A combustion mode control device controls the engine to operate at an air-fuel ratio leaner than a stoichiometric air-fuel ratio when the determining device determines that the operating condition of the engine is in a predetermined operating region.Type: GrantFiled: June 2, 2005Date of Patent: January 9, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Isamu Hotta, Toru Noda, Masaaki Kubo, Katsuya Moteki

Patent number: 6976469Abstract: A control unit is used for controlling a direct fuel injection type internal combustion engine. The control unit controls a fuel injection valve to have a first fuel injection mode wherein a penetration force of an injected fuel sharply increases at an initial stage of a fuel injection and thereafter an increasing rate of the penetration force gradually lowers with passage of time and a second fuel injection mode wherein the penetration force of the injected fuel sharply increases at a middle stage of the fuel injection. The control unit further controls the fuel injection valve in a manner to switch the first and second fuel injection modes in accordance with an operation condition of the engine.Type: GrantFiled: July 23, 2004Date of Patent: December 20, 2005Assignee: Nissan Motor Co., Ltd.Inventors: Masaaki Kubo, Atsushi Teraji, Koji Hiraya, Isamu Hotta
