EGR - MAF - Catalytic converter.
The pic below shows the EGR and the Mass air flow sensor.
Directly behind the turbo the catalytic converter is placed..
The EGR is closed trough a stainless steel plate.
If the EGR is closed no exhaust gasses will return into the engine.
Now there only remains a clean mixture of diesel and air.
This will give the engine more power, especially at low revs.
Trough this modification less fumagine will enter the engine.
The Mass-Air-Flow sensor
The MAF has come obsolyte becaurse of the diode modification.
The diode is a Philips BAV20 and is placed between pin 4 and 5 of the female-plug.
I've removed the ‘snowscreens’ from the MAFsensor housing. This to create a better airflow.
The Catalytic converter.
I still didn't empty the inside of the cat.
I've decided to wait because of the sharpened fumagine regulations in Holland.
