Abstract
A control system is described for a system that delivers hydrogen to the exhaust system of a vehicle and other parts of the vehicle. The control system controls the operation of valves for delivering hydrogen in a variety of different methods to the vehicle exhaust system, so the catalytic converter may be preheated in order to bring the catalytic converter to full functioning level very rapidly. The control system also controls the generation of hydrogen by electrolysis, the on-board diagnostics of the system, and the delivery of hydrogen to the vehicle's exhaust system.
