I ran across this in while reading Pounder’s Marine Diesel Engines and Gad Turbines by Doug Woodyard:
Author describes it as “an ingenious combination” of direct injection and precombustion chamber systems. It is cute, obviously.
What I wonder is: when the area exposed to the pressure suddenly changes as the piston drops, wouldn’t there be a shock to all the components between the crown and the crank? Have any of you worked on this kind of set-up? What do you think?
