While I don't know the specifics on the new Tdi, I can tell you that common
rail injection cannot work on any compression-ignition motor, (like the
Tdi). On a CI motor, the perfectly timed injection pulse of fuel into the
super-heated-compressed air is equivalent to the well-timed spark plug
firing on a lowly gasoline motor. Having the fuel injected on a common rail
(or like CIS), would be like lighting all the spark plugs at one time on a
common gasoline motor. Come-prend-day-vooo?

Hi,

Does "unit injection" mean common rail injection?
