Engine idle speed and turbocharger speed control

Image Number 12 for United States Patent #8131446.

Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection in response to a driver action. The first and second injection may be performed during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger.
