bob dunn Posted March 16, 2012 Share Posted March 16, 2012 Has anyone tried exp with carb filters or low pressure induction or H2O spraying ? Link to comment Share on other sites More sharing options...
piman Posted March 16, 2012 Share Posted March 16, 2012 Hello Bob, very many years ago racing cars tried using a ram air effect to increase air pressure at the carburettor, (free supercharging?) but they couldn't get the carburation right so the idea was abandoned. I guess it could now be done with electronics and a pressure sensor to regulate fuelling?Alec Link to comment Share on other sites More sharing options...
junkuser Posted March 16, 2012 Share Posted March 16, 2012 To get ram effect to work the whole of the carburetor and fuel tank has to be subjected to the same pressure. Tuning becomes very complicated."H2O spraying".If you mean something like the Kleinig water injection of the 1940s/50s, yes.Certainly did stop pre-ignition under load with the low octane fuels of the day.I did fit one to a Nissan 2 litre engine in a type two Transporter a while back for the fun of it as had found one at a swap, but not sure it was worth the trouble.

marktheherald Posted March 17, 2012 Share Posted March 17, 2012 When I had my Mk111 Zodiac with a Raymond Mays head, the triple SU bellmouths were just above the bonnet line. I never got around to making up a 'bulge' to cover them, for some reason it always seemed to go a lot better when it was raining heavily.... ::) Link to comment Share on other sites More sharing options...
bob dunn Posted March 17, 2012 Author Share Posted March 17, 2012 I think the story is that the rain cools the mixture in the cylinder. Link to comment Share on other sites More sharing options...
thebrookster Posted March 17, 2012 Share Posted March 17, 2012 Something like that, Bob. The maritime industries engine manufacturers (such as MAN B&W, Sultzer etc) have played with water injection again recently, due to all the new emissions requirements coming into play over the next few years, though they have I understand dropped it now.

Pete Lewis Posted March 18, 2012 Share Posted March 18, 2012 you get a better atomisation of the fuel with it attaching to the moisture particle, which also hold more H2 and Othan dry air...well something like that .tried this idea as a lad in the 60s by winding bundy around the downpipe of my sidevalve minxV ,, loads of steam from with a drip supply from a gravity reservoir...till it furred up and burst a tube.. did it work...dont remember , Pete Link to comment Share on other sites More sharing options...
