Abstract
A hybrid electric vehicle and a method for operating the hybrid electric vehicle in which combustion is made to occur within the internal combustion engine only after the crankshaft of the engine has been rotated by an electric motor or generator to a certain speed and according to a certain ramped or partially ramped profile thereby reducing the amount of emissions from the engine allowing for a more efficient torque transfer to wheels and allowing for a more smoother operation of the vehicle The fuel injectors throttle plate and spark plugs are also controlled in order to allow emissions to be reduced during activation of the engine and to allow the catalytic converter to be heated in order to allow these emissions to be further reduced as the engine is operating.
