Many modern diesels do have an injector rail, often refered to as "common
rail" diesel engines.  They have solenoid acutated injectors controlled by
an ECU i.e. they are very simmilar to injected gas engines, other than the
fuel pressure is an order of magnitude higher (~1600 Bar) and is injected
directly into the cylinder.
