Am NOT a diesel person, but am very interested in this thread...
Now that gassers are coming out with DICI (no spark plug) and assuming much higher gas PSI's...do they have a high pressure fuel pump similar to the diesel HPFP?
Learned a ton on that Bosch HPFP during the couple years reading up on a form members unfortunate experience
Pure dumb @$$ design by Bosch engineers. Made worse by management sticking with the original architecture and forcing band aids
Dumb @$$ by not capturing the piston to the cam and only depending on the fuel's PSI to force the piston to stay on the cam (caged desmodromic valve actuator would have been much better). Ditto using diesel as both lube and coolant (engine oil would have been much wiser). Ditto stacks of piezo silicon chip actuators in the injectors (glass is brittle).
Am in the hunt for info on the new gasser DICI fuel system, but not enough yet. Hope they didn't back themselves into a corner like the Bosch HPFP
