Publication number: 20140102402Abstract: A rotary internal combustion engine includes an outer housing and an inner housing defining an enclosure therebetween, and first and second side housings disposed on opposite sides of the outer housing. At least one of the outer and inner housings is rotatable relative to the other and at least two barriers are disposed in the enclosure and divide the enclosure into a combustion chamber and an exhaust chamber. At least one barrier is rotatable relative to at least one other barrier and at least one barrier comprises a retractable barrier mounted along a pivot axis and is pivotable between an extended position and a retracted position. An intake port, exhaust port, and ignition source are also provided. The rotary internal combustion engine further includes an intake opening formed in one of the side housings. The intake opening is intermittently fluidly communicating with the combustion chamber through the intake port.Type: ApplicationFiled: December 16, 2013Publication date: April 17, 2014Inventor: Scott HUDSON

Publication number: 20140102403Abstract: A control system in a gas engine includes a water injection means which injects water toward an interior of a cylinder in the gas engine; a water injection control means which controls the water injection section; and a knocking occurrence ratio measuring means which measures a measurement value of a knocking occurrence ratio in the cylinder. The water injection control means controls the water injection means to set the amount of the water injected toward the interior of the cylinder, based on a deviation between the measurement value and a target value.Type: ApplicationFiled: April 16, 2012Publication date: April 17, 2014Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Shintaro Yoshihara, Youhei Nakajima, Hidekazu Iwasaki, Kenji Yoshimura, Yoshishige Sakai, Yoshirou Tokunaga

Publication number: 20140102405Abstract: The application describes a system for an engine comprising a direct injection nozzle for injecting gaseous fuel into a cylinder of an engine in a second operating mode; an intake injection nozzle for injecting liquid fuel into an intake port of the engine in a first operating mode; and a valve gear suitable to adjust timing of opening and closing of an inlet valve. Preferential injection of a gaseous fuel such as compressed natural gas directly into the cylinder increases efficiency and allows for reduced heat exposure to the lesser used liquid gas injectors mounted in the intake port, reducing coking of these injectors.Type: ApplicationFiled: September 19, 2013Publication date: April 17, 2014Applicant: Ford Global Technologies, LLCInventors: Carsten Weber, Ulrich Kramer, Martin Wirth

Publication number: 20140102406Abstract: A compression ignition engine uses two or more fuel charges having two or more reactivities to control the timing and duration of combustion. In a preferred implementation, a lower-reactivity fuel charge is injected or otherwise introduced into the combustion chamber, preferably sufficiently early that it becomes at least substantially homogeneously dispersed within the chamber before a subsequent injection is made. One or more subsequent injections of higher-reactivity fuel charges are then made, and these preferably distribute the higher-reactivity matter within the lower-reactivity chamber space such that combustion begins in the higher-reactivity regions, and with the lower-reactivity regions following thereafter.Type: ApplicationFiled: December 17, 2013Publication date: April 17, 2014Applicant: Wisconsin Alumni Research FoundationInventors: Rolf Deneys Reitz, Reed M.

Publication number: 20140102407Abstract: Embodiments of injectors configured for adaptively injecting multiple different fuels and coolants into a combustion chamber, and for igniting the different fuels, are disclosed herein. An injector according to one embodiment includes a body having a first end portion and a second end portion. The injector further includes a first flow channel extending through the body, and a second flow channel extending through the body that is separate from the first flow channel and electrically isolated from the first flow channel. The first flow channel is configured to receive a first fuel, and the second flow channel is configured to receive at least one of a second fuel and a coolant. The injector further comprises a valve carried by the body that is movable between a closed position and an open position to introduce at least one of the second fuel and the coolant into a combustion chamber.Type: ApplicationFiled: April 16, 2013Publication date: April 17, 2014Applicant: McAlister Technologies, LLCInventor: McAlister Technologies, LLC
