  • Method for determining and compensating engine blow-through air
    Patent number: 9399962
    Abstract: A method for determining cylinder blow-through air via engine volumetric efficiency is disclosed. In one example, the method provides a way to adjust cylinder blow-through to promote and control a reaction in an exhaust after treatment device. The approach may simplify cylinder blow-through calculations and improve engine emissions via providing improved control of constituents reaching an exhaust after treatment device.
    Type: Grant

  • Method for restarting an engine
    Patent number: 9222453
    Abstract: Methods and systems for controlling an engine that may be automatically stopped and started are presented. In one example, a method adjusts a position of an air inlet throttle according to engine position and in response to an operator change of mind to restart an engine that is being automatically stopped.

  • Methods and systems for turbocharger control
    Patent number: 8439796
    Abstract: Methods and systems are provided for controlling a vehicle engine, the engine including a turbocharger and a transmission. One example method comprises, operating the transmission at a first lower gear with a first boost level, increasing the boost from the first boost level before completing a shift from the first lower gear to a second higher gear, and after completing the shift, operating the transmission at the second higher gear with the increased boost.

  • Methods and systems for turbocharger control
    Patent number: 8397499
    Abstract: Methods are provided for controlling a turbocharged engine having a throttle and a turbocharger. One example method comprises, moving the throttle during boosted conditions, separating out effects on the throttle inlet pressure into a first portion corresponding to disturbances caused by the movement of the throttle, and a second, remaining, portion. The method further comprises adjusting the turbocharger based on the second portion and not the first portion.
