a tobbirol asszem ismered a velemenyem, de az a porsche gyujtas, amit te
is lattal, egyszerre adta. Ugy volt bekotve, mintha ikergyujtas lenne, de
itt mindket gyertya egy hengerben volt.

[...] "This reduces the need for as much ignition advance to start and
finish the combustion process when the piston reaches Top Dead Center.
Since the spark event is starting closer to TDC in the compression cycle,
there is less pressure from the beginning of ignition that is pushing
'back' down on the piston crown as the combustion event progresses. This
lessens the 'negative' work done by the expanding gasses and allows all of
the pressure building in the cylinder to push the piston in the correct
direction, making the engine more efficient."

valamint:
"The Porsche 996 and Boxster water-cooled engines has a much more optimal
spark plug location at the top and center of the combustion chamber that
negates the need for two spark plugs per cylinder.  "

de ha rakeresel a neten, talasz egy csomo utalast vmi "phased twin spark"
nevu dologra, ami nem tudom micsoda; lehet, ennel nem egyidoben van a ket
szikra.
