Abstract
A diesel particulate filter of a motor vehicle is cleaned of ash, typically using equipment already available in a service shop. The filter apparatus is disconnected from the exhaust system of a motor vehicle. The filter apparatus is reversed and reconnected to the motor vehicle's exhaust system in a configuration opposite to which the filter apparatus was originally connected. The engine is started and allowed to run at a high idle and no load engine speed to blow ash from the diesel particulate filter into the exit tubing. The ash is then collected in an ash collector.
