Abstract
General Motors cars and light trucks for 1970 are equipped with improved Controlled Combustion Systems (CCS) or Air Injection Reactor (AIR) exhaust emission controls. An added feature on most vehicles is Transmission Controlled Spark (TCS) which extends the idle spark retard schedule for further emission reduction.
Cars sold in California are also equipped with an Evaporation Control System. A canister of activated carbon adsorbs and stores fuel vapor when the vehicle is not being used. Reactivation of the carbon occurs during vehicle operation, when the stored vapor is purged from the canister and metered into the engine where it is burned.
