The M.A.N. Marine Diesel Type M 6 v40/46 engines were started and reversed using air tanks. Each diesel engine had a 125L air tank that held air at 75 atm. A pressure reducing valve stepped the pressure down from 75 atmospheres to 30 atmospheres to start the engines.
For the latest release, I’ve added the simulation aspects to use air to start or reverse the engine. For now, no main air manifold is present so the tanks will not refill. After a single start, they will fail to restart again.
Double click the diesel motor to get more info on the engine and specs. As I dive deeper into the sim, more of the underlying components will be made interactible on the 2d schematic.
