What is Regen on a bus?
The lighter fluid (like extra fuel in an engine) causes a higher temperature burn and the smoke goes away temporarily. This is an active regen. When this happens, a “check engine light” is illuminated on the dashboard, and the bus must be parked, and the driver or technician must tell the bus to manually regenerate.
Can you regen a truck while driving?
Your truck can undergo the regen process properly while running, and will in fact, usually do so. Your diesel particulate filter, or DPF, undergoes routine passive regen as needed during steady driving. Active regeneration also occurs and happens best during highway driving speeds.
How do you manually regenerate a DPF?
To kick off a manual DPF regeneration you should
- Put the vehicle in neutral.
- Put on the hand brake.
- Leave the pedals alone!
- Press and hold the DPF button for 2 seconds or longer.
How long does a parked regen last?
How long does a parked DPF regen take? It takes approximately 20-60+ minutes. It will continue to regen until the soot level has reached ‘low’ or ‘0%.
Will parked regen stop on its own?
A Parked Regeneration will stop if the key is turned to the off position, the truck is put into gear or the parking brake is released. The regeneration will take approximately 20-40 min. The regeneration is complete when the engine returns to low idle and the DPF lamp remains off.
How often should you do a forced Regen?
Retrofit DPFs must also be cleaned—CARB and supplier regulations require cleaning retrofits at least once a year, or at about 1,000 hours of engine operation.
How long should a regen take?
A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.
How much does a forced regeneration cost?
Some garages can clean blocked DPFs, in a process called forced regeneration. This usually costs around £100 and, while it’s not a 100% guaranteed fix, it’s usually successful in removing the excess soot and allowing the DPF to work and automatically regenerate again.
Do buses have Dpfs?
The DPF technology for buses makes it possible to improve air quality, reduce health risks and help to keep the work place diesel smoke free.
What is a diesel regen cycle?
An active regen cycle is a normal process that takes place as the truck is going down the road. A computer sensor monitors the DPF and a dashboard indicator light notifies the driver that the regen is taking place, or the DPF is now cleaning. “You’ll notice a reduction in power during a regen,” notes Nace.
How do you regen a Thomas school bus?
You need to call Thomas with the body number and ask them how the bus is set up to run a parked regen. Bus in nuetral, park brake set, high idle or normal idle, doors open or closed, a/c on or off. All of those will effect the ability to activate a parked regen.
