    Abstract: The heat-insulating piston structure (10) according to the present invention is formed by fixing a piston head (4), which consists of a material the coefficient of thermal expansion of which is substantially equal to that of a ceramic material, to a piston skirt (2), and setting a thin, flat plate (5) portion of a ceramic material on the whole of the flat surface of the piston head which is on the side of a combustion chamber via a heat-insulating member. Accordingly, the piston (10) can be formed so that it has excellent heat-insulating character­istics and high thermal resistance, deformation resistance and corrosion resistance. Especially, the thin plate portion of a ceramic material (5), which is exposed to a combustion gas, can be formed to the smallest possible thickness to reduce the thermal capacity thereof greatly. Therefore, the temperature of the wall of the combustion chamber varies easily with that of the combustion gas (in other words, the amplitude of the temperature of this wall becomes large). Consequently, a difference between the temperature of the thin plate portion of a ceramic material and those of the gases (combustion gas and suction air) becomes small momentarily, so that the heat transfer rate of the thin plate portion decreases. This causes a decrease in the quantity of heat which the suction air receives from the wall surface. As a result, the suction air smoothly enters the combustion chamber without being expanded therein. This enables the suction efficiency and cycle efficiency to be improved.

    Abstract: A one-piece single-gap ceramic piston ring (30) is mounted in a top groove (24) below a reduced-diameter head land of a piston (16) to form an assembly. Preferable use of an L-shaped ring cross-section and high strength ceramic material provide a ring (30) capable of being installed over the head land while maintaining opening and closing strains within the ultimate strain capability of the ceramic material of the ring (30).

    Abstract: Les moteurs à combustion interne conventionnels à injection directe n'allument pas ni brûlent complètement des carburants à indice de cétane relativement bas, tels que l'éthanol ou le méthanol à 100 pour cent, étant donné que le jet pulvérisé de carburant injecté ne peut en général communiquer ou propager une flamme à la totalité du carburant injecté, lequel se compose généralement de courants individuels de carburant séparés par des poches d'air d'admission pauvre en carburant. Le système de combustion de carburant ci-décrit (10) comprend un dispostif de déclenchement d'allumage de carburant (26) tel qu'une bougie à incandescence (70) et un dispositif (98, 102) permettant de relier par contact et d'unir en continu tous les courants individuels de carburant (66) à l'aide d'un nuage auxiliaire (94) de carburant bien atomisé. De cette manière, une flamme déclenchée par le dispositif de déclenchement d'allumage de carburant (26) peut se propager rapidement et complètement par l'intermédiaire du nuage auxiliaire (94) de carburant à tous les courants individuels de carburant (66).
