do glow plugs effect timing

[Crash]

Hello men,

I need some help from my nitro gurus.

how does a glo plug effect the timing of a engine?

Is it possilble to change the timing by changeing the glo?

I am not a guru, but I can't see how a glow plug (that's lit the entire time unlike a spark plug) could affect timing of an engine.

well I now it does, I just need a better understanding of it

Technically a glow plug engine is similar to a diesel engine in that it uses internal heat to ignite the fuel, but since the ignition timing is not controlled by fuel injection (as in an ordinary diesel), or electrically (as in a spark ignition engine), it must be adjusted by changing fuel/air mixture and plug/coil design. A richer mixture will tend to cool the filament and so retard ignition, slowing the engine. This "configuration" can also be adjusted by using varying plug designs for a more exact thermal control.

What thunderhawk said is correct. Depending on if you use a normal or short plug, cold/ medium or hot, this will effect when the nitro is ignited in the engine. When the nitro is ignited and how completely it burns decides the timing. This is my understanding of how it works.

Thanks for the info.

Yup...A hotter glow plug will fire the mixture sooner, thus advancnig the ignition timing. The reverse is of course true as well...a colder plug retards the ignition.

Timing affects power of 1:1 engines big time. I have never noticed an increase or decrease in power going from a cold to hot plug. Maybe its just too little to notice.

I knew you guys would know, thanks.
