摘要： A multi-link engine has a piston coupled to a crankshaft to move inside an engine cylinder. A piston pin connects the piston to an upper link, which is connected to a lower link by an upper link pin. A crank pin of the crankshaft rotatably supports the lower link thereon. A control link pin connects the lower link to one end of a control link, which is connected at another end to the engine block body by a control shaft. The upper link has an upper link axis that forms an angle with the cylinder axis, as viewed along a crank axis direction of the crankshaft, such that the angle reaches a minimum when a crank angle of the engine is within a range where the bottom end of a piston skirt is positioned below a topmost part of the bottom end of the cylinder liner.

摘要： A direct fuel injection engine basically comprises a combustion chamber, a piston with a cavity, a fuel injection valve, a spark plug and a control unit. The fuel injection valve is configured and arranged to directly inject a fuel stream into the combustion chamber in a substantially constant hollow circular cone shape in a stratified combustion region. The control unit is configured to ignite a first air-fuel mixture formed directly after the fuel stream is injected and prior to a majority of the fuel stream striking the cavity when the direct fuel injection engine is operating in a low-load stratified combustion region, and to ignite a second air-fuel mixture formed after a majority of the fuel stream is guided by the cavity toward an upper portion of the combustion chamber above the cavity when the direct fuel injection engine is operating in a high-load stratified combustion region.
