Maybe it has been covered & I didn't search enough ;[
Spark timing for LPG burning is around 16 deg before TDS.
HHO spark timing at 8 deg after TDS with the waste spark eliminated.
Can HHO be used with LPG (at around 1.5 lpm) is the main question
![Question :?:](./images/smilies/icon_question.gif)
I'm thinking if spark timing can be progressively varied from TDS at
idle (with HHO trickling in) to 8 deg after TDS (after 1,100rpm) that
maybe LPG & HHO can be used together. An impulse reading of the
rpm could be used to vary the spark timing. I'm thinking out loud here
& would like to hear pros vs cons by people in here. Feasable ?
Cheers !
