Modern Agricultural and Construction machinery is full of emissions-control equippment.
But this equippment can lead to a lot of headaches because of reliabilty issues and down time.
There are 3 main emissions-control systems Manufacturers use:
DPF:
The Diesel Particle Filter in your exhaust pipe.
This filter needs constant cleaning (regeneration)
Most of the time the machine itself can do that regereration process.
But sometimes a machine needs to be stationary to make the regeneration process.
In some cases it is even necessary that the cleaning/regeneration process gets done by a technician.
As the Diesel Particle Filters gets older it may even be necessary to change them out completely due to very high ash leves in the filter which clogs them up completely.
EGR:
The Exhaus Gas Recirculation.
The job of the EGR is as the name suggests to recirculate a part of the exhaust gases back in to the intake system of the engine.
As you can imagine constantly redirecting a part of the exhaust gases back in the engine is not the best thing that can happen to a engine, it increaes the intake temperatures, can lead to a soot buildup on the intake valves and channels and EGR valves are also known to start leaking after longer use.
AdBlue/SCR/DEF/Urea:
The Exhaust Fluid known as Adblue.
Depending on the region and the manufacturer it has diffrent names like Adblue, SCR, DEF, or the Urea system.
But it all means the same thing.
It's the fluid you need to top up in addition to your Diesel which you need to refill already anyways.
This system works in a way that it injects this Exhaust Fluid in to the exhaust system and trys to reduce the emissions this way.
But this system is known to produce a very fine ash which is also very bad for the invorenment.
Those AdBlue/SCR/DEF/Urea systems are also well known to be very fragile and extremely unreliable, not to mention the high cost of currently purchasing the stuff.
So when and why do you want to delete those emissions-control systems from your machine if it's not already obvious?
DPF:
In general you can leave the DPF untouched until it starts to cause headaches. Which it most likey will.
With a delete you can save heaps of money on a new filter or the technician charges of replacing it and constantly cleaning the Filter.
EGR:
It's always a good idea to gid rid of the Exhaust Gas Recirculation because keeping the internals of an engine clean is quite important.
Or when the Valve starts to leak or gets stuck it's also a great time to delete this system instead of spending tons of money to repair the EGR.
AdBlue/SCR/DEF/Urea:
The two main reasons you'd want to delete this system are firstly the annoying topping up of the Exhaust Fluid,
and secondly the astronomically high costs of reparing the system when it breaks, which it will do almost certainly.
