- HCAT (Heated Catalyst): This refers to a system in some vehicles that preheats the catalytic converter, aiding in more efficient emission control. However, it's worth noting that many modern cars, including models from the early 2000s, may not have this system due to advancements in engine programming.
- AIR (Air Injection Reaction): This was a system used primarily in the 90s to help catalytic converters burn cleaner and more efficiently by preheating them. Like HCAT, advancements in vehicle technology have made this system obsolete in newer models.
