I'm cc'ing your post to the eec-iv list to see is someone can help you out -- also, I'd like to hear any responses you get.

Makes you back off the throttle real fast. In my mates Alfa it just sounds like small ticks, bit like worn lifters. Dan dzorde@xxx.com > >>Have any one seen the instrument that Link is offering ?

They sell systems in Australasia, Malaysia, California, England and Sweden. I have rung Philip to get his mail addy, he is going to mail me so that the addy is correct. Once he does this I'll post it. Link ElectroSystems Ltd. PO Box 9166 Christchurch New Zealand Ph: 0064 3 3488854 Fax 0064 3 3481595 If you get in touch with them tell them that you heard about them from this mailing list .......(I'm hoping for a discount when I upgrade ;-) Cheers Simon +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Simon Quested (E-mail questeds@xxx.nz) Computer Technician, Silicon Graphics & Windows NT Support Centre for Computing and Biometrics LINCOLN UNIVERSITY OF NEW ZEALAND Phone (64)(03) 3252811 Ext. 8087 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ http://www.lincoln.ac.nz/ccb/techs/simon/default.htm +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ f u cn rd ths, u cn gt a gd jb n cmptr prgmmng +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ------------------------------ From: Simon Quested Date: Tue, 29 Jul 1997 10:23:15 +1200 Subject: Re: Knock sensors, was Re: Ignitition Controllers Hi Brian and everybody > 4 cylinder turbo-ford engines have 'em low on the side of the > inlet manifold.

Air is 78% Nitrogen and 21% Oxygen. The molecular weight of Nitrogen (diatomic molecule) is 28 g / mole. The molecular weight of Oxygen (also diatomic) is 32 g / mole. The molecular weight (roughly, using above ratios) is 28.6 g / mole. The are 22.4 moles of gas per liter (by experiment) at 0 degrees C and 1 atm. Using the Ideal Gas Law, the number above comes to 24.1 moles / L at 20 C. There is 28.3 liters per cubic foot (sees like alot). Now, mix it all together and x (g of air / sec) * (1 mole of air / 28.6 g of air) * (1 liter of air / 24.1 moles of air) * (1 cubic foot of air / 28.3 liters of air) * (60 seconds / 1 minute) EQUALS x (g of air / sec) * 1 / 325 = y (cubic feet of air / minute) So divide the grams of air per second by 325 to convert to cubic feet of air per minute. NOTE: With air flowing, this conversion will have a higher than actual reading in cubic feet per minute. That ol' compressibility of air comes in to smuck up everything. Thanks Bernoulli....
