.I don´t think it makes sense to have more sparks per combustion. You achive no higher energy by doing this.
Tell that to MSD and the tens of thousands of racers that use it.

I was referring to something like stratified charge.. Maybe the can make multiple injections/sparks "synchronized" whit the turbolences in the chamber.. Stratified charge has good efficiency because the combustion is insulated from the cylinders by the sorrounding air.. And with limited fuel, efficiency is the way to go.. imho..matt21 wrote: You have something like this in diesel engines.
But this is mostly for comfort and emission reasons, e.g. small injection prior to main injection results in a smoother cylinder pressure curve.
If the efficency is high enough and fuel left they can have some kind of anti-lag with late injection/ignition.
MSD systems say somewhwere that they make 1 spark per combustion event above 3000 rpm (multiple sparks at lower rpm)strad wrote:.I don´t think it makes sense to have more sparks per combustion. You achive no higher energy by doing this.

the point of stratified charge is surely to combust a mixture so lean overall that it would not combust well as a uniform mixture ?stez90 wrote: I was referring to something like stratified charge..
