EGR (Exhaust Gas Recirculation)

It is a system that aims to reduce the heat generated as a result of combustion by directing (recycling) some of the exhaust gas in internal combustion engines back into the engine and into the cylinders, thus keeping environmentally harmful nitrogen oxide gases (NOx) under control. It is widely used in today's gasoline and diesel engines.

The mixture of fresh air entering the engine with burnt exhaust gas reduces the combustion temperature and (in diesel engines) the amount of excess oxygen. Since the formation of NOx gases accelerates at high temperatures, controlling the temperature also helps control the formation of harmful NOx gases.
Contrary to popular belief, a well-functioning EGR system increases the efficiency of gasoline engines.

FUNCTION OF EGR (Exhaust Gas Recirculation)

EGR (Exhaust Gas Recirculation) is a system used to reduce emissions in internal combustion engines. The EGR system changes the engine's combustion process and reduces harmful emissions by directing some of the exhaust gases back into the combustion chamber. This system is used specifically to reduce nitrogen oxide (NOx) emissions.

1. Function:

The EGR system returns some of the exhaust gases to the engine's intake manifold. This reduces the amount of oxygen in the combustion chamber, lowering the combustion temperature. Lower combustion temperatures reduce NOx formation because NOx emissions occur more at higher temperatures.

2. Working Principle:

Recirculation of Exhaust Gases: The EGR valve redirects some of the exhaust gases to the intake manifold. These gases mix with clean air and return to the combustion chamber.

Reducing Combustion Temperature: Returning exhaust gases slow down the combustion process in the combustion chamber and lower the temperature.
Reducing NOx Emissions: Lower combustion temperatures significantly reduce NOx emissions.

COMPONENTS OF EGR (Exhaust Gas Recirculation)

  • Exhaust gas recirculation valve.
  • Exhaust gas recirculation valve sensor.
  • Exhaust gas recirculation cooling block.
  • Exhaust gas recirculation temp and pressure sensors.

PROBLEMS OF EGR (Exhaust Gas Recirculation)

  • Limp mode problem
  • Malfunction light coming on (Check Engine Light)
  • Black smoke seen in the exhaust.
  • Increase in Fuel Consumption
  • Erratic Idle

NUOVOLTA SOLUTION OF EGR (Exhaust Gas Recirculation)

  • Official diagnostic tool must reset the relevant module.
  • DTC codes should be read and removed with a diagnostic tool
  • Apply the solution of the module related to NUOVOLTA
  • Write the mod file to the ECU
  • Check the dashboard and DTC logs. Take it for a test drive
  • If all the checks are OK, it means the problem is solved

ECUs supported for EGR Removal

Grouped by ECU manufacturer, most requested first.
