Low compression, EH> low octane explosions are just less violent; the fuel burns EH> slower. I think you got it backwards. Low octane gasoline is more volatile than high octane gas. The knock and ping you hear from low octane gas is the result of preigition of the cheap gas (poping off before the sparkplug sparks). The higher the compression of an engine, the more likely preignition will occur, so the less volatile higher octane gasoline (which used to refer to the amount of "octane" in the fuel, as opposed to the more volatilte heptanes and hexanes. Since then other compounds that burn more slowly have been added to raise the "octane" rating of fuel). You might say "But Ken, if the higher octane fuel burns slower, how come it's used in hi performance engines?" The answer is, that with higher octane fuel, you can control the combustion process with spark, rather than the fuel mixture just going off at random (knock and ping). With hi octane gas you can dial the distributor in to the most power with high compression!

The answer is, that with -> higher octane I wouldn't SAY that, but all of this is immaterial where A-Bones are concerned. The LOW compression ratio produces a 'soft', slow burning explosion, and I sincerely doubt you can MAKE a model A ping and/or preignite, with ANY fuel. It might not run real good on peanut butter but I sincerely doubt it'd ping. (Too little volatility?) ^..^ --- FidoPCB v1.5 beta-'j' * Origin: BOO!

Hi, Mike! MD> I'll look into that. But now here in Kamloops I'm looking at a MD> nice '69 Plymouth Barracuda. That brings back memories. After the car I learned to drive in (a '69 Mustang) got creamed by a dump truck without brakes, my Mom got a '69 Barracuda, with 318, automatic. I spend a lot of time cruising in that vehicle. I ran an open-reel tape deck in the back using a power inverter. Only got it stuck once at the beach while on a camping trip. I've got a '60 Valient Suburban stationwagon in the front yard that just quit running. I changed points, condensor and plugs, but it still won't start. Hope to find time to work on it again soon.

My speedo light is out on my 1985 Toyota Camry: Symptoms are the light will go on and off, with it mostly off. We replaced the rheostat on the &ront panel with one we got at the wreckers --- new one at the dealer is $95 !!!!! We then got lights to the speedo, but after a few days, the lights started to go off, and sometimes come back on. Now it is off all the time. We are brainstorming that problem could be: - Another part of that circuit? - These rheostats are a common failure problem when installed, but will test good at the wreckers - ?????? Anyone got any ideas? Thanks! Pete ...

Older engines relied on the lead to lubricate parts... VAlve Guides and Seats mostly. But once one of those older cars gets a good coating unless it is Driven VERY hard the lead will last quite a long time in this day of Unleaded gas. And then one can always use Modern materials fro the Guides and seats that don't require lead to reduce wear. --- InterEcho 1.19 * Origin: Node (1:202/815) --------------- FIDO MESSAGE AREA==> TOPIC: 155 OLD CARS Ref: DFB00001 Date: 11/05/96 From: LANDON ROBINSON Time: 03:07pm \/To: STEVE RHODES (Read 3 times) Subj: Re: Chevy engine SR> i have a 69 chevelle that has a 307 in it. the motor has about 250000 SR> - 300000 MILES on it and its still going. im sticking a 350 in it over SR> the winter but this engine just wont die and belive me i tried lots of SR> times to kill it :) Why oh why does that thing have a 307 in it ?

I think the main point that the octane has to do with is clenliness, it burns more completely, and the Nitrides of oxygen it leaves behind are more easily removed by the catalytic convertor, and are less harmfull to the environment. I'm not too sure as to what would be less volatile, but your idea does seem right. I think though that the main thing that causes the improvment in power could be with how much the compound expands when burnt... Maybe it expands more, and also, the higher-up gas burns more fully and completely, therefore you get the most from the fuel. -Mike Dale ___ X SLMR 2.1a X It's only a hobby ... only a hobby ... only a --- Maximus 2.02 * Origin: Digital Encounters * Kamloops BC Canada 604/374-6168 (1:353/710)
