The four-stroke cycle
I quattro tempi del diesel
Remember. A diesel runs on two things: air and clean fuel. The battery is only needed to start it, not to keep it running (except on engines with a stop solenoid).
Watch out. A diesel has no spark plug: ignition comes from the hot compressed air, with the injector spraying the fuel. Drawings with a spark plug show petrol engines.
