Carl Sambell Posted April 21, 2006 Share Posted April 21, 2006 Anybody experienced problems with emissions failing an SVA test on Blackbird engined car. Engine is injection using a CAT. Basically too much fuel going in. Any idears much appreciated Quote Link to comment Share on other sites More sharing options...
stu999 Posted April 21, 2006 Share Posted April 21, 2006 Fuel pressure too high? Quote Link to comment Share on other sites More sharing options...
nexus Posted April 21, 2006 Share Posted April 21, 2006 I have suggested fuel pressure too high to Westfield, but they assure me that the V8 fuel pump is the correct one for the engine. 2 Fuel regulators are used, one from Westfield, the other from Honda Quote Link to comment Share on other sites More sharing options...
BuGsBuNnY Posted April 23, 2006 Share Posted April 23, 2006 Carl, Have you got a full breakdown of values for CO2, HC and O2? It appears the mixture is too rich so could either be a faulty or dead lambda sensor if you got one (2001 engine only) or could possibly be a missfire or weak spark on your plugs. I would start at the plugs, then check leads and coils, then lambda. Fuel pressure is unlikely to be an issue as that would mean that both your regulators are not working. Try an inline fuel pressure gauge if you are still unsure. Quote Link to comment Share on other sites More sharing options...
Carl Sambell Posted April 24, 2006 Author Share Posted April 24, 2006 Hi CO is around 3.5% HC is 82ppm Lambda is 0.91 A lambda sensor is fitted to this engine as it is a 2000 model Thanks Carl Quote Link to comment Share on other sites More sharing options...
Carl Sambell Posted April 24, 2006 Author Share Posted April 24, 2006 Meant to say Lambda Sensor not fitted as engine is a 2000 model Quote Link to comment Share on other sites More sharing options...
BuGsBuNnY Posted April 24, 2006 Share Posted April 24, 2006 Carl, It sounds like I thought. I would follow my previous post and check ingition (plugs, leads, coils). Check fuel pressure with an inline gauge (get one from any motor factors or halfords) and finally, if all else fails, check your cat isnt damaged (just in case), although unlikely with a new-ish engine. Having said that, if it has been overfuelling for quite a while, the cat may have been damaged and require replacing. Quote Link to comment Share on other sites More sharing options...
