Really interesting, thanks. Shows you how much I know about real truck engines. I love the idea of complete "cylinder packs" that you can just swap into an existing block. Makes perfect sense.
About how much more would an articulated piston cost over a one-piece unit for the same application? Any reason you can think of why we haven't really seen them in gasoline engines? Is it the slow heat transfer of a steel crown?
What is piston "secondary motion"? Same as "piston rock"?
