摘要： When a cylinder block is cast, a bearing housing is constituted by a preform integrally cast with the cylinder block. In order to raise the strength of the bearing housing, a metal matrix composite is formed around the preform. The preform is constituted by a high volume factor member having a relatively high volume factor and two low volume factor members having a relatively low volume factor connected with top and under surfaces of the high volume factor member respectively. The high volume factor member is made of solid metal and the low volume factor member is made of sintered metal filaments. Base material of the cylinder block infiltrates into the low volume factor member to form a metal matrix composite in the preform.

摘要： A part of a piston is composed of a metal matrix composite. The metal matrix composite is composed of a matrix of a light metal alloy and reinforcements formed of metallic fibers mixed in the matrix. The reinforcements are formed of an alloy that consists mainly of Fe and Cr and contains Al and/or Si. The Cr content and the Al and/or Si content of the reinforcements range from 5 to 30% and from 3 to 10%, respectively. The fiber diameter of the reinforcements ranges from &phgr;20 &mgr;m to &phgr;100 &mgr;m. The reinforcements are formed by the melt extraction method and have irregular peripheral surfaces. Solution-treatment of the metal matrix composite is carried out within a temperature range from 470° C. to 500° C. such that formation of intermetallic compounds is restrained.

摘要： A direct injection engine in which an injector injects fuel toward a cavity formed in a top surface of a piston to produce a locally distributed mixture around a spark plug is constructed such that the direction of a fuel spray ejected from the injector is varied during a fuel injection period to properly spread the mixture and prevent its local overrichness. The direct injection engine is provided with means for generating a swirl, for example, so that the fuel spray from the injector is directed toward the spark plug when the pressure in a cylinder is low in a compression stroke, and the fuel spray is deflected by the swirl away from the direction of the spark plug as the pressure in a cylinder increases.
