    摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

    摘要： A piston crank mechanism of an internal combustion engine includes an upper link connected to a piston, a lower link connected to both the upper link and a crankpin, and a control link through which the lower link is linked to an eccentric cam of a control shaft to restrict the degree of freedom of the lower link. By varying the angular position of the eccentric cam with respect to the control-shaft axis, the center of oscillating motion of the control link varies, thus varying a compression ratio. The center of gravity of the lower link, determined by an equivalent inertia weight obtained by adding weights of connecting pins and weights of the upper-link boss-shaped end and the control-link boss-shaped end connected to the lower link via the respective connecting pins to the lower-link self-weight, is situated closer to the center of the crankpin.

    摘要： An engine control system for a direct injection-spark ignition type of engine which is equipped with an exhaust system having a lean NOx conversion catalyst for lowering a NOx level of exhaust gas while the engine operates in a lean fuel charge zone controls the engine to make stratified charge combustion in a zone of partial engine loadings and homogeneous charge combustion in a zone other than said partial engine loading zone and, while the engine operates in a zone where enriched homogeneous charge combustion is made, divides a given amount of fuel into two parts and sprays them through early and late split injection in a intake stroke and admits exhaust gas partly into an intake air stream introduced into the intake system from the exhaust system while the early and late split injection are made. The split injection are caused such that a midpoint between points at which the early and late split injection are timed to start before a midpoint of a intake stroke.
