Abstract
Accelerated heating of automotive exhaust system components is effected by controlling the application of supplemental electrical loads to the vehicle electrical system thereby increasing engine load and increasing exhaust heat. Alternative strategies are disclosed for implementing the invention through control of electrical and engine management system parameters.
