Abstract
A method is provided for controlling emissions in a parallel hybrid motor vehicle that includes an electric propulsion system in parallel with a combustion propulsion system. In accordance with one embodiment of the invention, manifold absolute pressure (MAP) is monitored in the intake manifold of the combustion propulsion system. The electric propulsion system is engaged to reduce the MAP to a predetermined pressure, and then fueling and combustion of the combustion propulsion system are initiated only after the MAP is reduced to a pressure less than the predetermined pressure.
