Embodiment Construction

[0015]The present invention includes a collection of modules that may be internal combustion engines, regenerative electric motors, engine generators, turbine generators and battery banks.

[0016]The components can be switched in and out to work together to achieve a lowest overall operating cost and / or minimizing harmful emissions.

[0017]A minimum system contains at least one main engine. In a preferred embodiment, the main engine is a tandem combination of an internal combustion sub-engine and an electric machine sub-engine. A typical twin propeller application can utilize two main engines. These are normally configured with the same equipment; however, it is within the scope of the present invention to configure the two main engines differently in a twin propeller application. A single main engine can also drive two or more propellers.

[0018]The main engine(s) is normally mechanically coupled to the propeller shaft(s). The system can include a generator module or modules, either as a...

Abstract

A marine propulsion and power supply for maritime vessels that includes an arrangement of modules that can be internal combustion engines, regenerative electric motors, engine generators, turbine generators and/or battery banks. These components can be arranged in such a way as to work together to increase efficiency and to utilize various fuel combinations to achieve the lowest overall operating cost or other goals whilst minimizing harmful emissions. Sensors can be used monitor various power parameters and can be coupled to a closed-loop in a control system to achieve vessel operating goals.

Description

[0001]This application is related to, and claims priority from, U.S. Provisional patent application No. 61 / 657,965 filed Jun. 11, 2012. Application 61 / 657,965 is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to marine propulsion systems and more particularly to a multi-propulsion, multi-fuel marine power system.[0004]2. Description of the Prior Art[0005]Typical marine propulsion systems usually have a main engine or a pair of main engines. Many times these main engines are diesel. The main engine or engines also often drive a generator that is used for battery charging. The battery is used primarily for starting the engines.[0006]A major problem with prior art systems is that they can only run on one fuel. Usually this is diesel fuel for larger vessels. In some cases, smaller vessels may instead have gasoline engines; however, these are usually recreational vessels.[0007]It would be very advantageous to ...
