A component package designed to eliminate the Exhaust Gas Recirculation system in specific PACCAR MX13 engines. This system is originally intended to reduce nitrogen oxide emissions by recirculating a portion of an engine’s exhaust back into the cylinders. The deletion involves physically removing EGR components and often requires reprogramming the engine control unit (ECU) to prevent error codes and ensure proper engine operation.
The impetus for removing the aforementioned system often stems from concerns regarding its impact on engine performance, fuel economy, and maintenance costs. Recirculated exhaust can introduce soot and contaminants into the intake manifold and engine cylinders, potentially leading to increased wear, reduced efficiency, and more frequent maintenance interventions. Historically, such modifications have been pursued to enhance engine longevity and operational reliability, particularly in demanding applications.
