Hey there all.

Just a question that popped into my head while reading the TS thread below.

If the TS engine has two seperate distributors, one on the block and one camshaft driven I believe. Are the timing curves for both of them identical? Is the timing set so that both plugs in each cylinder spark at the same exact moment? Or is one of the distributors advanced or retarded with regards to the other distributor? And what effect might this have on the operation of the engine?

I've not had the chance to have a proper look at a TS engine myself.

Looking forward to your answers
Guy

Hi
TS ignition is controled by Motronic !!! distributors just distribute spark to spark plugs i think early motronic fires both plugs together ... later 16 v TS motronic have staged ignition(helps only for economy and emissions)

Guy,I did a ts motor in an lds Alfa a few years back .This is a 400kg open wheeler type racer.I used the 2 dist. as you mentioned and tried everything from timed spark to phased interval spark.I even removed one set of plug spark and found no difference in the power that the little engine made.The set of two sparks did approximatly halve the amount of timing needed by the engine though....
