Presentation
KAD/KAMD44P* and KAD/KAMD300* are in-line, direct injected 6-cylinder marine diesel engines, specially
developed for planing boats.
They are equipped with electronically controlled fuel injection, a mechanical supercharger, turbocharger, intercool-
er, heat exchanger for thermostatically controlled fresh water cooling, electronically controlled engine speed con-
trol and shifting.
The supercharger provides the engines with air at low speeds, and at higher speeds the turbocharger provides the
air supply. This interaction gives the engines extremely high torque at all engine speeds.
