Dar Zellon....you are completely and utterly incorrect about your detonation "theory'.
And about detonation, a rich mixture can even cause detonation, due to the
sheer volume of the fuel, increasing the resultant compression pressures (liquid fuel is incompressible).
A rich mixture cannot "cause detonation" in any way shape, or form.
DETONATION :
Definition: An unwanted explosion of the air/fuel mixture in the combustion chamber
caused by excess heat and compression, advanced timing, or an overly lean mixture.
Detonation, or "knock", greatly increases the mechanical and thermal stresses on the
engine. Also referred to as "ping".
So, from where I am looking, the richness of the mixture, the magnitude of
which is achieved using the fuel needles, is the glow engine's equivalent of turning the
distributor in the direction of its rotor's rotation, or in the opposite direction, in your
car's engine.
This statement is incorrect as well. The compression ratio of a glow engine is the
primary factor that determines the firing point (ignition) of the fuel charge.
The reason I brought this up, is I don't want inexperienced Members taking
misinformation from these RCU boards.
