Publication number: 20140283785Abstract: A control device of a spark-ignition engine is provided. The control device includes a main body of the engine, a fuel injection valve, an ignition plug, and a controller. According to an operating state of the engine, the controller switches an ignition mode between a compression-ignition mode in which compression-ignition combustion is performed by causing the mixture gas to self-ignite and combust, and a spark-ignition mode in which spark-ignition combustion is performed by igniting the mixture gas with the ignition plug to combust. The controller switches the ignition mode from the spark-ignition mode to the compression-ignition mode by performing a transition mode in which a temperature inside the cylinder is forcibly decreased and combustion is performed.Type: ApplicationFiled: February 14, 2014Publication date: September 25, 2014Applicant: Mazda Motor CorporationInventors: Toshiaki Takahashi, Junichi Taga, Kouhei Iwai

Patent number: 8552211Abstract: Disclosed is a dry oil-and-fat separation method of high yield and high separation accuracy, which uses agitation and crystallization in order to prevent problems with thickening of the crystal slurry and decreased solid/liquid separation efficiency in the crystallization/press-filtering process of dry separation of oil-and-fat containing highly crystalline SUS. In dry separation, the crystallization/press-filtering process is divided into multiple steps and repeated, to concentrate the SUS in each crystal fraction and yield SUS-rich oil and fat. Subdivision into multiple steps makes it possible to keep the crystallinity of the crystal slurry in the crystallization/press-filtering process within a range so that the crystal slurry can be transported by pump, and to increase solid/liquid separation efficiency.Type: GrantFiled: January 27, 2010Date of Patent: October 8, 2013Assignee: Fuji Oil Company, LimitedInventors: Koreta Ueyama, Toshiaki Takahashi, Kenji Murai, Shin Yoneda
