four-stroke engine ;
Diesel ;
or gas turbine.
Diesel engines are by far the most widespread. It drives :
or an electric generator (alternator) powering electric motors driving the axles; this is the electric transmission;

or the axles via a gearbox-type reduction unit; this is the mechanical transmission (rarely used).
The electric drive is the most advanced for high-power...
