I have been thinking about the oil percentage, but I can not see how using a spark plug would allow to reduce the oil content, in fact being able to run with a leaner mixture will reduce the amount of oil entering the engine. On gas engines I understand that you can use a much lower oil content because of the lubricant properties of gasoline (not the case with methanol). Anybody can help explain this?


Ecco la spiegazione:


With a glow, the moment and duration of ignition of fuel is not controled.
When there is compression, ignition starts and temperature in cylinder increases.
So oil is used not only to lubrifiate but also to refresh. That what is oil is about 20 or 22 %. With Electronic Spark, ignition is at the good moment. So oil is only used to lubrifiate. 15 to 17 % methanol replaces oil and gives to engine more power.


Per Artù

Il kit per la trasformazione del 170 glow dovrebbe essere disponibile con la fine di Gennaio 2009 (peso totale 4,5 once = 128 grammi.....):
