    First came the cat. It was hailed as being the solution to the environmental problems cars would cause. What did the cat really do? It prevented the lean burn concept taking of and lu,bered us with higher fuel consumption.. It was claimed theat the CO and the HC output as well as the nitrous oxide emission would be so harmful and kill our planet.

    Hmm. Why then did weeds and grass thrive along motorways more than anywhere else? And what they don't tell us till date is that the cat produces H2SO3. Not some nice stuff. Even worse is that the cat produces cyanide. Take all the cars on the planet that have a cat and collect the cyanide they produce annually and you can kill in excess of 10 crore adults instantly. Nice way of slow poisoning. And there s more to the cat.

    5-8% increased fuel consumption means that you have to pay for every 20 tank loads another basically for the luxury of having an 'environmentally friendly' trap attached to your car.

    Well, that can't be all the industires is lumbering us with. Of course, it can't be. Such a thought would be insame. The industries had to act. We blessed us with another contraption. The Diesel powered cars got a DPF.

    What actually does the DPF do. Well, it collectes particules that are not burnt in a filter, which loses the engine more power as km are clocked up and when the ECU decides it is enough, lots of fuel will be thrown to the filter and the whole rubbish will be burnt out.

    Why on earth do they not burn it in the combustion chamber? Because it would mean engineers have to wreck their brains. And this costs money and money must not be spent.

    Removing the DPF instantly gains power and saves fuel. The fuel saved is between 5 and 10%. Additionally re-mapping can save between 5 and 15%. This is a worthwhile improvement. It is good for the economy and the environment.

    BTW, removing the DPF is not very difficult and deleting of the ECU setting in order to prevent that the ECU kicks up a fuss is not too hard too.

    If you can't sort it and want it to be sorted, feel free to contact me.

    yes not yet in indian multijets..DPF's would get clogged way too early due to bad quality of diesel fuel available here in india.....

    also a question regarding CAT's... does a car with CAT needs to be run a bit rich @ high RPM's than a car with same engine without CAT ?

    Well written and good real revealing information Drifter. Well, most legislation's are brought in / forced in by the industry govt combination to keep the engine of the economy going including the sham called Global warming.. If we will understand that and we want to save our pocket and planet, then we have the right to do it the way drifter suggests. Did I go :eek:fftopic ?. Sorry

    They need a bit leaner mixture, but this is not possible for hi load as this would not get the vehicle up to speed and neither cruising when facing high levles of drag.

    No, you just were touching on what we need to day. It is about time that we ask the ones in chafge to take responsibility for waht they are doing.

    All FIAT Diesel cars currently sold have the DPFs installed. Can be checked by looking under the car when its on a lift.

    MJD's meet Euro IV requirements without DPF. I think only Ford Euro IV diesel engines in India have DPF fitted. (Not sure though)
    If Linea and Punto had DPF's fitted you wouldn't have noticed black smoke from exhaust under hard acceleration.

    Interesting piece of info. My simple belief is that an engine is most environment friendly when in travels the maximum distance for a given amount of fuel. :anyone
