Emissions

Hi. I have a 52 plate SX 1100. It went for MOT but the test was abandoned as the cooling fan was not working. Got that fixed, but apparently the emissions were also looking too high. Whatís the best and cheapest way to fix or improve emissions? It has been off the road to 6 months so I am hoping a good thrashing might help, any other ideas please? Thanks

Re: Emissions

Re: Emissions

A full service and a damn good thrashing (When fully warm) will do no harm.

Italian tuning....

Re: Emissions

mine always struggles through emmissions every year. i put it down to a cheap catalytic converter.
a good thrash does tend to help though

Re: Emissions

the post 2000 seicentos all have a manicat so they dont benefit from the thrash as much. with the spi cat being right down and behind the engine it doesnt get that hot just idling at the test centre but manicats get hot really fast, its why all cars have them these days. Good thrash never hurts but actual results would point you more in the correct direction of things to try that just ranting it and hoping for the best.

Re: Emissions

If the beast has been standing a long time, then chances are the various sensors might have just degraded/corroded a bit.

It may be worth carefully cleaning the MAF sensor (fit a new air filter ans stick new plugs in it while you're there) and then checking the lambda operation, particularly if the beast doesn't idle very well.

The cat' could be a bit sick but let's hope not. Put 300ml of kerosene (parafin.. i.e. not white spirit) in a full tank of fresh fuel and take the beast out for a drive to get it hot. You don't have to rev the b'jesus out of it.. just variable revs to get some action through the injectors and enough heat to help dissolve any gum or varnish.

Re: Emissions

It's like giving your car an enema..

They basically run a shed-load of solvents through the system and that cleans out any garbage, moths, sawdust, soot, gum, varnish and the like. It goes in instead of the petrol.. and the stuff in there produces more oxygen as it combusts, which burns off some of the down-wind parts (cat, DPF and exhaust) so reducing soot and making those work better.

It may be worth a punt if the more gentle "stick some kerosene in the tank" method doesn't do it.
