In this video, Dave discusses the issue of emission control systems in engines, specifically in the context of trucks. He mentions that these systems can make decisions on behalf of the driver that may not always be safe, and tells a story about an incident where a truck’s emission control system caused the truck to lose power and the Jake brake to turn off while the truck was going down a mountain with a heavy load. Dave suggests that these systems can cause problems for drivers and may not always be worth the investment, noting that “newer isn’t always better.” He also mentions that engines are not designed to burn 0 emissions and that the new emission control systems are causing trouble for drivers.

Watch, and listen as he describes his friend’s most recent incident with an emission style engine.
