EGR valve what is it?
The EGR valve is located between the intake manifold and the exhaust manifold where it acts as a communicator, allowing part of the exhaust gases to return to the combustion chamber through the intake manifold to be burned again. This step generates a drop in the combustion temperature, which directly affects the reduction of nitrogen oxide (NOx) emitted and discharged abroad.

Driving at low revs and high gears makes the EGR work most of the time. 
Especially driving in the city is the one that can cause the most problems for the EGR valves and particulate filters, especially in diesels.
EGR causes many of the mechanical failures in internal combustion engines. After an engine gets a certain mileage EGR becomes a problem, accumulating soot in the intake system passages and on the engine valves.
All this causes the engine to no longer work efficiently.

A lot has been written on this topic about the pros and cons of removing egr.

  • Reducing nitrogen oxide NOx emissions
  • Less pollution (up to certain kilometers)
  • emergency mode
  • Increased fuel consumption
  • reduced power
  • Soot buildup in the engine
  • Catalyst clogging
  • increased engine wear
There are cases where it is necessary to completely remove the EGR valve. Complicated repairs in which finding the problem is necessary to disable the EGR temporarily, competition vehicles, special purpose vehicles, etc.

The removal of the EGR is by customer's decision! Chip Cars offers global software modification services in various countries around the world. The user must consult the legal regulations in their country.
