Where is the DPF purge air actuator located?
Driver side of the engine below the fuel filter is the solenoid valve with a 1/4″ nylon air line feeding the valve. Its job is to purge the fuel from the fuel supply line and the fuel doser when the dosing process for regen is completed. Depending on your fault at hand you may have a voltage fault or a response or mechanical fault.
What is aftertreatment purge air valve air supply line routing?
Title: Aftertreatment Purge Air Valve Air Supply Line Routing for both Cummins ISX SCR Engines and N13 with SCR Engines Applies To: ProStar, TransStar , PayStar, 9900i. ISX Cummins SCR, N13 SCR DESCRIPTION Proper AFT Purge Valve air line routing.
Where is the purge air actuator on a MX EPA 10?
The purge air actuator on a MX epa 10 functions in the same manner and is essentially the same part as on a Cummins. Driver side of the engine below the fuel filter is the solenoid valve with a 1/4″ nylon air line feeding the valve.
Where is purge air valve air supply routing?
Proper AFT Purge Valve air line routing. POSSIBLE FAULT CODES SPN 3490 FMI 7 Cummins Fault 3225 SERVICE PROCEDURE N13 with SCR The engine air supply is run directly from the manifold on a Bendix ADIS dryer, used in all ProStars, and off the secondary air tank on all other units not equipped with the AD-IS dryer.
Where does the aftertreatment purge air supply line run?
Both configurations are shown below. The line runs up the driver side frame rail where it T’s off to the Aftertreatment Purge Air Valve, continuing on to a reducer fitting just below the valve cover on the driver side, from here it runs around the front of the engine to supply air to the Air Control Valve (ACV).
What does DPF do to a diesel particulate filter?
The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. The collected diesel soot particles are burnt off at high temperatures, which results in an “ ash-like ” after product.
How does forced catalytic converter affect DPF levels?
Manufacturers that use a passive form of regeneration typically install a oxidizing catalytic converter near the engine to increase the temperature. Forced is where the Active regeneration could not occur that has resulted in the soot levels reaching 70% and above.
What should I do if my DPF light is blocked?
With that in mind, here are 5 ways to fix a blocked DPF: Drive Faster. If you are driving slowly everywhere in your large diesel, the DPF will become blocked. Increase Your RPM. If the DPF light is on, your best bet is to drive at high RPM’s for a prolonged period until the warning lights turn off. Avoid City Centers.
What happens when a DPF goes wrong in a car?
DPF’s are great for the environment and so forth, however they are a right pain when they go wrong. DPF regeneration, repairs and new replacements are seriously expensive and can lead to some vehicles becoming scrapped. How does a DPF Work in Diesel Cars? What causes DPF failure? Have You Bought The Wrong Car? How does a DPF Work in Diesel Cars?
When does the DPF warning light come on?
Average rating from 137 customers who received a Warning Light is on Inspection. Diesel particulate filters are intended to reduce soot emissions by as much as 80%. When the filter fails, the DPF (diesel particulate filter) light will come on. It indicates a partial blockage in the filter.
Where is the air supply line on a Cummins ISX 15L?
Cummins ISX 15L with SCR Since the ISX does not have an ACV the only concern we have seen on this application is that complete line is missing from the either the auxiliary manifold (AD-IS Dryer) or the secondary air tank pressure protection valve (all other dryers). Both configurations are shown below.
