Publication number: 20100199944Abstract: A piston is coupled to a connecting rod which is rotatably coupled to a crankshaft via an extension rod. With the configuration, reciprocating motion of the piston is transmitted to the crankshaft and converted to rotational motion. At both ends of the extension rod, a piston-side joint mechanism and a crankshaft-side joint mechanism each constructed by a spherical sliding bearing are provided. The piston is coupled to the extension rod via the piston-side joint mechanism, and the extension rod is coupled to the connecting rod via the crankshaft-side joint mechanism.Type: ApplicationFiled: August 26, 2008Publication date: August 12, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaaki Katayama, Hiroshi Yaguchi, Daisaku Sawada

Publication number: 20100199946Abstract: Fuel management system for enhanced operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder. It is preferred that the direct injection occur after the inlet valve is closed. It is also preferred that stoichiometric operation with a three way catalyst be used to minimize emissions. In addition, it is also preferred that the anti-knock agents have a heat of vaporization per unit of combustion energy that is at least three times that of gasoline.Type: ApplicationFiled: February 5, 2010Publication date: August 12, 2010Applicant: Massachusetts Institute of TechnologyInventors: Daniel R. Cohn, Leslie Bromberg, John B. Heywood

Publication number: 20100199948Abstract: Disclosed is a method and corresponding fuel injector for injecting gaseous and liquid fuel into an engine. The method comprises delivering a liquid fuel to a fuel injector, delivering a pressurized gaseous fuel to the fuel injector, entraining the liquid fuel within the gaseous fuel within a chamber of the fuel injector and injecting the gaseous fuel and atomized liquid fuel into the combustion chamber. The liquid fuel can be passed through and dispensed from a needle into a chamber in the injector nozzle where it is entrained in the gaseous fuel during an injection event. The liquid/gas mass ratio is controlled by the needle movement, hydraulic resistances or electronic valves so that the majority of the liquid is injected during the first part of the gas injection. The injector can be used for late cycle direct injection of natural gas, or any number of gaseous fuel blends combined with many liquid fuels such as diesel, biodiesel and DME.Type: ApplicationFiled: June 29, 2007Publication date: August 12, 2010Applicant: The University of British ColumbiaInventors: Steven N.
