    摘要： An engine having a cylinder, a piston slideably received in the cylinder, a crankshaft connected to the piston, and a multi-link piston crank mechanism. The multi-link piston crank mechanism controls movement of the piston such that an acceleration of the piston at top dead center is less than an acceleration of the piston at bottom dead center. A determining device determines an operating condition of the engine. A combustion mode control device controls the engine to operate at an air-fuel ratio leaner than a stoichiometric air-fuel ratio when the determining device determines that the operating condition of the engine is in a predetermined operating region.

    摘要： An internal combustion engine includes a main combustion chamber and a small auxiliary combustion chamber. The main chamber is formed by a cylinder, the undersurface of a cylinder head, and the crown of a piston. A main ignition unit is disposed in the cylinder head, including a main body and a spark plug. The auxiliary chamber is formed within the main ignition unit. The main and auxiliary chambers are connected via a communication passage. The piston crown includes a cavity. When a fuel injection valve sprays fuel into the cavity on compression stroke, a tumble flow of fuel gas is generated to locally form a relatively rich air-fuel mixture near the communication passage. The air-fuel mixture partly flows into the auxiliary chamber as the piston travels upwardly. The air-fuel mixture in the auxiliary chamber is ignited by the spark plug so that a combustion flame propagates into the main chamber.

    摘要： An direct fuel injection spark ignition internal combustion engine comprises a fuel injection valve arranged at a substantially center part of an upper are of a combustion chamber, and a piston having a crown surface with a cavity shaped so that a center axis of a substantially conical-shaped fuel stream injected from the fuel injection valve is substantially coincident with a center axis of the piston. In a low-load stratified combustion operating region when spark ignition is executed, the fuel injection angle is increased to form a first combustible air-fuel mixture before the fuel stream collides against the cavity of the piston crown surface. In a high-load stratified combustion operating region, the fuel injection angle is reduced to form a second combustible air-fuel mixture after the fuel stream collides against the cavity of the piston crown surface.

    摘要： A reforming catalyst (6) induces an isomerization reforming reaction and a decomposition reforming reaction of a gasoline fuel. Injectors (27, 33, 35, 36) supply an isomerized fuel generated by the isomerization reforming reaction and a decomposed fuel generated by the decomposition reforming reaction respectively to the internal combustion engine (1). The ratio of the isomerization reforming reaction and the decomposition reforming reaction depends on a catalyst temperature, and can be altered arbitrarily by controlling an air supply amount to the catalyst (6) via an air amount regulating valve (14) and a fuel supply amount to the catalyst (6) via a fuel injector (8) and thereby controlling the catalyst temperature.

    摘要： A contact includes a support member, a first spring portion, a second spring portion, a third spring portion and a fourth spring portion. The first spring portion extends obliquely upper forwardly from an upper end of the support member and has, at an apex, a first contact point which contacts with an IC package. The second spring portion is bent from the first contact point, to extend obliquely lower rearwardly and have a first touch portion. The third spring portion extends obliquely lower forwardly from a lower end of the support member and has a second contact point which contacts with a printed-wiring board, thus being in contrast with the first spring portion with respect to the support member. The fourth spring portion is bent from the second contact point, to extend obliquely upper rearwardly and has a second touch portion for contacting with the first touch portion.
