The EGR Valve

EGR Valve

EGR valve

The EGR valve controls a small passageway between the intake and exhaust manifolds. When the valve opens, intake vacuum draws exhaust through the valve. This dilutes the incoming air/fuel mixture and has a quenching effect on combustion temperatures which keeps NOX within acceptable limits. As an added benefit, it also reduces the engine's octane requirements which lessens the danger of detonation (spark knock).

BG Diesel Air Induction & EGR service

The EGR service cleans more that just the EGR valve. Cleaning the EGR valve alone will be a very short term solution (at best) to the problems of accumulated deposits in the EGR system. The BG EGR service will clean the EGR valve and the channels (where most of the deposits accumulate).


  • The EGR service can be adapted to clean turbo blades
  • This service will restore power and reduce Nox emissions


BG ISC® Induction System Cleaner

Quickly and safely cleans EGR valves and channels, fuel injectors and remove hard, baked-on carbon deposits from intake ports, intake valves and combustion chamber. It is introduced to the system using a special tool. For complete cleanup

Reducing carbon deposits


One by-product of combustion is carbon, the black soot that can collect and harden on the cylinder head, cylinder wall, piston and valves. Carbon deposits in the combustion chamber can affect engine performance, resulting in higher oil consumption, engine knocking or overheating.

This service will reduce your carbon deposits.
