A novel hydride cold-start heater for automotive catalysts has been successfully designed and tested. It is clearly capable of dramatically reducing cold hydrocarbon emission and even achieving ULEV performance from a conventionl catalyzed automobile. The HCSH has certain advantages over alternative emissions control systems. It is passive, automatic and requires no significant electrical input (except for solenoid valve control). However, for this hydride based device to be shown as fully competitive, particularly with hydrocabon traps and electrical heating, further work on minimizing production cost and confirming good cycle life must be carefully done. In conclusion, the potential should exist for a new and near-term hydride application in the automotive catalyst industry. In addition, there are other potential applications that may benefit from 'instant preheating'.
