Detroit Diesels of older 2 stroke engines were actually supercharged and turbocharged – the supercharger would start the engine, and once it was running, the turbos would take over. cc is correct, yes.

Do reed valves make a difference?

They improve the engine’s fuel efficiency by helping to control the flow of the fuel/air mixture as it is pumped from the intake tract to the combustion chamber.
