According to http://www.motoring.co.uk/car-news/new-mot-rules-punish-diesel-particulate-filter-removers_59657?utm_source=motoring.co.uk&utm_medium=newsletter&utm_campaign=newsletter&src=motoring.

 

" New rules mean that any vehicle missing its diesel particulate filter will - from February 2014 – fail the MOT test. The purpose of the device is to filter the residual particulate matter caused by incomplete combustion of the fuel, matter which would normally then escape into the air through the exhaust. This material incorporates carbon, organic chemicals, sulphate, nitrates, ammonium, sodium chloride and mineral dust which pollute the environment. "

 

Now I wonder what is the work around going to be?

panic, but also discussed in several threads! :(

Hooray

Another DPF removal thread

Next person to start a DPF thread gets a special holiday.......

:rofl:

In all fairness, hand on heart, I can honestly that this is the first DPF thread I've seen........

........and my name?

It still doesn't detract the fact that an diesel engine chucks out more harmful chemicals than a petrol engine even with a diesel engine particulate filter..

Hooray

Another DPF removal thread

 

Come on Bryan at least it's not tyres     :think:

But does removal stop the windows misting up in Winter I wonder.......

Wrong. Studied automotive emission control systems when I was at uni. A diesel engine puts out around one third of pollutants produced by petrol engines. The problem is that the particulates (smoke) are easily seen whereas petrol emissions are virtually invisible. This gives the impression that diesels pollute more but they don't.

 

Diesels:

The particulates are now controlled by DPF. Flame propagation is more controlled with the newer CR very high pressure injection systems and ECU so burns the diesel more completely.

Sulphur pollutants are reduced significantly by low sulphur diesel.

Diesel engines burn fuel more efficiently and completely hence the higher MPG.

 

Petrol engines produce more pollutants, HC, CO, NOx, Benzine.

 

Both produce CO2 as the CAT's built into the exhaust system converts CO into CO2.

Both have EGR valves which introduce a small amount of exhaust gas into the conbustion chamber to keep the burn temp below 1800 deg C. Above this temp, NOx (nitrogen oxides) are produced.
