Bob Corb Posted October 24, 2005 Share Posted October 24, 2005 The spec for the R500 injector (0280 155 868) according to my resident Bosch engineer is "282 g/min at 3.5 bar". Link to comment Share on other sites More sharing options...
CharlesElliott Posted October 24, 2005 Share Posted October 24, 2005 According to the Bosch website: 261.1 g/min @ 3 bar 3.5 bar operating pressure Charles --- My SuperGraduates 2005 diary My Caterham Academy 2004 build and race diary Link to comment Share on other sites More sharing options...
Mike Bees Posted October 24, 2005 Share Posted October 24, 2005 Well the good news is that those 2 sets of figures tally! What fuel pressure does the R500 run at? If it's 3.5 bar then those injectors are only marginally big enough shirley? Mike Link to comment Share on other sites More sharing options...
knowley Posted October 24, 2005 Share Posted October 24, 2005 Too large on the R300 so I am told 🙆🏻 Link to comment Share on other sites More sharing options...
Graham Perry Posted October 24, 2005 Share Posted October 24, 2005 Can you consider 'g' and 'cc' as the same units when dealing with petrol as I notice both measurements are mentioned above ?

Paul McKenzie Posted October 24, 2005 Share Posted October 24, 2005 No, adjust for sg of petrol - 0.74g/cc Paul Link to comment Share on other sites More sharing options...
Dobuy Posted October 24, 2005 Share Posted October 24, 2005 I had a quick Google and Ebay turned up these here which look like the ones in my Duratec, pretty good value, compared with what I paid! Duratec SV, built in Dubai Link to comment Share on other sites More sharing options...

Mike Bees Posted October 25, 2005 Share Posted October 25, 2005 Ah, good point Graham - I'd read it as 261.1 cc/min not g/min. So they're 353cc/min which is pretty damned large, tho' maybe the R500 runs them at 3 bar not 3.5, so ~327cc/min. Some of my notes on this from the dim & distand past state that Injector ratings are usually quoted for N-heptane, though some Weber injectors are quoted for Exsol-d40 whatever that is. Needless to say these give slightly different figures, which are also slightly different from the figures you get for petrol. Ramble ramble...
