摘要:
A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed on the top surface of the piston, and a fuel injection valve for injecting fuel into the cavity in nearly the flat fan shape having a relatively small thickness. An opposing side wall of the cavity opposite to the fuel injection valve, for leading the fuel to the vicinity of the spark plug, has an arcuate portion having a plurality of arcuate shapes in a plan view. The radius of arcuate shape at the both side parts of the arcuate portion in a plan view is smaller than the radius of arcuate shape at the center part of the arcuate portion in a plan view. The opposing side wall has a deflecting portion to deflect the fuel toward the inside of the cavity.

A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a cavity formed on the top surface of the piston, a spark plug facing the inside of said cavity, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relative small thickness. The cavity has a bottom wall onto which the injected fuel impinges initially and a side wall facing to the fuel injection valve. The side wall has a deflection portion which is nearly the shape of a linear line and a circular arc portion which connects the deflection portion and the bottom wall smoothly in a vertical section. An angle of the deflection portion with the bottom wall is in a range from 50 to 80 degrees. A radius of the circular arc portion is in a range from 5 to 15 mm.

A data storage means stores data in a predetermined information form. An information retrieval means retrieves the data stored in the data storage means. A reception means receives an information disclosure demand from a demander, a response rule storage means for storing general knowledge for generating a response responding to the demander and a personal relationship information associated with a unique personal relationship between a user having the data on an information provider side and a user on an information demander side. A response plan formation means, responsive to the demand received by the reception means, plans a response for exhibiting, to the information demander, data obtained by causing the retrieval means to retrieve the data stored in the data storage means on the basis of the knowledge and the personal relationship information stored in the response rule storage means. A response generation means generates the response to the information demander in accordance with the plan formed by the response plan formation means.
