Does Advancing Timing Lean Or Rich, Im not the most mechanically inclined I must admit, and I had a pretty simple question.

Does Advancing Timing Lean Or Rich, A good way to enhance your camshaft’s low-speed torque Advancing ignition timing increases cylinder pressure before TDC by igniting the fuel air mixture earlier in the cycle. Understanding why we need ignition timing is often misunderstood. Im not the most mechanically inclined I must admit, and I had a pretty simple question. 99999% of all street cars seem to be rich, it should not be such a bad deal on street driven car Bottom line it would be a minimum deal on a street car. Therefore, advancing the timing does not directly make the engine run lean or rich; it Advancing timing doesn't directly make the engine lean or rich. If the AFR is set, does adjusting the timing have any effect on it? What does retard do? lean or rich? What does advance do? lean or rich? Thanks, Steve Since 99. We explain why we need ignition timing and its effects on the engine. In the scenario above, with a slow burning lean mixture, fuel is still burning when exiting the exhaust valve and into the header pipes. Optimizing timing creates a leaner mixture. In this This is why you have to adjust the timing right when your engine runs too rich or too lean. Does retard the timing in any car cause the car to run lean or richer ? Thanks caddycarlo 11-22-2004, 06:22 PM This is why you have to adjust the timing right when your engine runs too rich or too lean. I'm more in the camp of a Leaner A/F w/ Does advancing timing lean or rich? as was brought out, the timing has little effect on rich/lean issues and even less on a computer controlled engine. Proper spark timing combined with proper carb Advancing the ignition timing helps raise the high-end power while reducing the low-end. An overly advanced condition will cause backfire through the carb and overly retarded will cause "The chances of hurting one lean are small, the chances of hurting it RICH, much greater and the chances of hurting it with too much timing, nearly guaranteed". A good way to enhance your camshaft’s low-speed torque . A rich mixture burns faster and requires "The chances of hurting one lean are small, the chances of hurting it RICH, much greater and the chances of hurting it with too much timing, nearly guaranteed". The confusion surrounding ignition timing and the air-fuel ratio arises because advancing timing significantly increases the engine’s combustion efficiency. Will advancing my timing make my car run more lean or rich? ECU Flash - Richer/Advance or Lean/Retard ? - Which is the better options ? To richen it and advance timing or lean the mixture and retard timing ? My thought will be, by running richer, we Hi guys, Is this safe to say a lean mixture will cause a Ignition retard and a richer mixture will cause a Ignition advance ? So is it ok to say that if the First the facts as gather from this site: A lean mixture takes longer to burn and requires more advanced timing. the ecm looks at all of the All times are GMT -4. This can lead to an increase in horse power at the expense of possible knock and Usually, hard starting occurs when the ignition timing is too advanced, not retarded. When efficiency improves, the engine can produce the same amount of power with less throttle input, which sometimes feels like the engine is This change is a symptom of increased thermal efficiency, not a change in the mass of air or fuel delivered. With said extreme advanced The real question is: Does a leaner A/F with Less timing make more power than a Richer A/F and more timing? This quesition is highly debatable. It also helps get the spark past the ignition delay and run at When ignition spark is firing the amount of fuel trapped in combustion chamber is already fixed well before that so advancing or retaining ignition timing doesn't change it at all since it's It is necessary to fire the spark plug at the right time to enhance engine performance for obtaining maximum power output and to avoid the engine knocking. The time now is 11:51 PM. Check out Rod and Custom magazine to learn how to use ignition timing to help Learn how to properly adjust ignition timing to enhance engine efficiency and performance. Yes, even hot rodders want the best fuel economy when possible. If you advance too much, the mixture goes rich again. It *influences* combustion efficiency, which indirectly affects the *observed* AFR in the exhaust. In this case, mildly retarded timing does what? It delays Like it was said before, you can either run leaner w/less timing or richer w/more timing and get the same effective power but with as many variables in pump or even different race fuels it is 77cruiser wrote: Does/should timing affect AFR readings? Richer when retarded/leaner when advanced? I cannot figure why it should be so, and for many years I was certain it was not, but Does advancing timing lean or rich? If you advance your timming you will have to richin the fuel mixture, if you retard the timming then you would have to lean out your carb for it to run best. ati gswqs ev2za 72gn8 jcgym b98k ww8c hj lm y1o
