  • Publication number: 20130133152
    Abstract: A wiper blade with a wiper strip, in the lateral longitudinal grooves of which spring rails are inserted as springy supporting elements. The ends of the spring rails are connected with one another by a bridge in that side parts of the bridge are supported at the upper side of the spring rail and engage recesses of the spring rails, whereas a middle part of the bridge bridges a back strip of the wiper strip, which forms the upper boundary of the longitudinal grooves. It is proposed that the spring rails, at their front faces, have short slots, which extend in the longitudinal direction of the spring rails and which are engaged by the I-shaped angle pieces of the bridge. Lower legs of the angle pieces are directed towards the middle of the spring rails, gripping these from below.

  • Publication number: 20130131957
    Abstract: Systems and methods are provided for transitioning between a first combustion mode and a second combustion mode in an internal combustion engine. A current operating point of the engine is identified and a target operating point for the internal combustion engine in the second combustion mode is also determined. A predefined optimized transition operating point is selected from memory. While operating in the first combustion mode, one or more engine actuator settings are adjusted to cause the operating point of the internal combustion engine to approach the selected optimized transition operating point. When the engine is operating at the selected optimized transition operating point, the combustion mode is switched from the first combustion mode to the second combustion mode. While operating in the second combustion mode, one or more engine actuator settings are adjusted to cause the operating point of the internal combustion to approach the target operating point.

  • Publication number: 20130125544
    Abstract: A method for switching between low- and high-dilution combustion modes in an internal combustion engine having an intake passage with an exhaust-driven turbocharger, a crankshaft-driven positive displacement supercharger downstream of the turbocharger and having variable boost controllable with a supercharger bypass valve, and a throttle valve downstream of the supercharger. The current combustion mode and mass air flow are determined. A switch to the target combustion mode is commanded when an operating condition falls within a range of predetermined operating conditions. A target mass air flow to achieve a target air-fuel ratio corresponding to the current operating condition and the target combustion mode is determined. The degree of opening of the supercharger bypass valve and the throttle valve are controlled to achieve the target mass air flow. The amount of residual exhaust gas is manipulated.
