Abstract
Systems and methods for operating an engine and a transmission to reduce a catalyst light off time are disclosed. In one example, clutches of a transmission are operated to provide a desired load to the engine so that engine combustion stability may be improved while supplying heat to a catalyst so that the catalyst light off time may be reduced.
