  • Patent number: 8948987
    Abstract: An internal combustion engine 1 at a standstill of a vehicle after cold starting can switch its combustion mode to a homogenous combustion mode or a stratified combustion mode. An operation range of the stratified combustion at the standstill of the vehicle after cold starting is expanded relative to an operation range of the homogenous combustion at the standstill of the vehicle after cold starting as an inclination of the vehicle decreases. With this technique, the operation range of the stratified combustion can be expanded while assuring an intake air negative pressure required for achieving the brake performance, so that HC reduction at the standstill of the vehicle after cold starting is obtained.

  • Patent number: 8100097
    Abstract: 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 crank pin has a center arranged on a straight line joining centers of the upper link pin and the control link pin such that an angle formed between the straight line and a horizontal axis that is perpendicular to a center axis of the cylinder and that passes through an axial center of a crank journal is the same for at top dead center and at bottom dead center.
