Re: DIFFERENCES BETWEEN DIESEL REGEN SYSTEMS
Posted to Technical Discussion Forum on 1/11/2023 2 Replies

Like Justin said above, the systems are very similar across makes. The biggest difference, I would say, is how the systems have changed over time. In 07 when DPFs were first installed on trucks, there was no DEF, and fuel was injected into the exhaust system using the engine fuel injector being fired during the exhaust stroke. (A poor system, as evidenced by the use of dedicated fuel injectors on the later systems).
