20090241883 | CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE SYSTEM, AND INTERNAL COMBUSTION ENGINE SYSTEM - The invention relates to a control method for an internal combustion engine system, capable of preventing an internal combustion engine in a state after being automatically stopped, from falling into an unrestartable state. Upon satisfaction of a given automatic stop condition, the engine | 10-01-2009 |
20090101103 | ROTARY PISTON ENGINE AND METHOD FOR DESIGNING THE SAME - A rotary piston engine includes a generally triangular rotor, a pair of side housings, a rotor housing which is assembled with the rotor and the pair of side housings to define three working chambers, an intake port formed in at least one of the side housings, and an exhaust port formed in at least one of the side housings. The length of one side of the triangular face of the rotor is at least 2.4 times the breadth of the rotor. | 04-23-2009 |
20090099012 | CATALYST-SUPPORTED PARTICULATE - A catalyst layer formed on the walls of exhaust gas channels in a particulate filter contains a catalyst material in the form of secondary particles, each secondary particle being formed so that at least two kinds of primary particles selected from the group consisting of primary particles of activated alumina, primary particles of a Zr-based mixed oxide and primary particles of a Ce-based mixed oxide are mixed and cohere together. Each of the primary particles of the Zr-based mixed oxide contains Zr and a rare earth metal Z other than Ce and each of the primary particles of the Ce-based mixed oxide contains Ce, Zr and a rare earth metal R other than Ce. | 04-16-2009 |
20090088282 | AUTOMATIC TRANSMISSION - In an automatic transmission, a planetary gear set is disposed adjacently to an end cover and configured such that its inner peripheral face of a carrier is rotatably supported on an outer peripheral face of a boss portion provided at the end cover. A lubricating-oil supply passage comprises an oil passage formed from the end cover to the boss portion, an oil passage formed in the carrier so as to tightly connect to the oil passage at the inner face of the carrier, and an oil passage formed in the pinion shaft so as to tightly connect to the oil passage and reach an outer peripheral face of the pinion shaft. There is provided a lubricating oil supply means for supplying lubricating oil to the bearing portion via the above-descried lubricating-oil supply passage. | 04-02-2009 |
