Abstract
Systems and methods for increasing engine vacuum production and catalyst heating of a hybrid powertrain are described. In one example, a motor/generator rotates an engine at idle speed while the engine combusts air and fuel without providing torque sufficient to rotate the engine so that spark timing may be advanced or retarded from minimum spark timing for best torque to heat a catalyst and generate vacuum for vacuum consumers.
