What is an emissions flush on a diesel engine?

An emissions flush on a diesel engine is a maintenance process designed to clean the exhaust system, particularly the diesel particulate filter (DPF) and related components. This procedure typically involves using specialized chemicals or solvents to remove soot, ash, and other deposits that accumulate over time, which can hinder engine performance and increase emissions. Regular emissions flushing can help maintain compliance with environmental regulations, improve fuel efficiency, and extend the lifespan of the engine.
