Abstract
A marine propulsion unit which includes a propeller selectively coupled directly or by way of gear systems at least to two diesel engines with the propulsion unit being adapted to be operated, in a medium speed range of the ship, with only less than all of the engines and, in a higher speed velocity of the ship, with all engines. At least one of the propeller and the stepdown gear system is constructed so that the propeller, during normal operating conditions and while being propelled by the diesel engines utilized in the range of up to the medium velocities, absorbs the maximum constant output of these engines with the full amount of fuel being injected and, with a maximally permissible engine speed and that, when operating with all engines, the higher propeller speeds are retained in the range of the higher velocities by increasing the speeds of the engines without exceeding their maximum constant output and with a corresponding reduction in the amount of fuel injected to the respective engines.
