摘要： A solid catalyst component for olefin polymerization catalysts prepared by suspending diethoxymagnesium (a) in an aromatic hydrocarbon (b) which is liquid at normal temperature and bringing the suspension into a first contact with titanium tetrachloride (c) to form a product and bringing it into a second contact with tianium tetrachloride (c) in such manner that a diester (d) of an aromatic dicarboxylic acid and calcium chloride (e) are allowed to coexist at any stage of the above suspending and/or contacts, the calcium chloride (e) being used in an amount of 1-2 grams per gram of the diethoxymagnesium (a). This solid catalyst component exhibits, when applied to the polymerization of olefins, a surprisingly enhanced polymerization activity per titanium atom and a high stereospecific performance and scarcely necessitates any deashing treatment, thus affording a great economical advantage.

摘要： The present invention relates to a variable operation angle mechanism that can improve engine performance at transient operation by optimally setting a ratio between change amounts of opening and closing timings accompanying a variation in valve operation angle of intake valve, and relates to an apparatus for and a method of controlling an engine including the variable operation angle mechanism. In the variable operation angle mechanism, ratio RIVO of change amount of opening timing IVO of intake valve to change amount of valve operation angle is set to be 20% or more and 40% or less, and preferably, to be 30%. In engine including a variable valve timing mechanism varying a rotating phase of intake camshaft relative to crankshaft and the variable operation angle mechanism, a target phase change amount varied by the variable valve timing mechanism is corrected for phase change amount accompanying the variation in the valve operation angle.

摘要： There is provided a configuration in which a cylinder which is in an inlet stroke when an internal combustion engine is in a stop (automatic stop) state is determined and stored, and when starting the engine upon detection of a start request, the fuel injection of an initial cycle to the cylinder, which has been determined as having been stopped in the inlet stroke when the engine was in the stop state before starting, is split into a plurality if injections at least including an injection before engine rotation, to thereby perform injections. As a result, startability is improved while suppressing pre-ignition at the time of starting.
