Fuel trim system for multiple drive propulsion systems
First Claim
Patent Images
1. A fuel trim system for minimizing fuel consumption on a marine vessel with multiple drive propulsion systems while maintaining a predetermined steady state speed comprising:
- a thrust sensor disposed on each drive system;
a fuel flow meter disposed on each drive unit;
a tachometer disposed on each drive unit;
a global positioning system;
a microprocessor in electrical communication with the thrust sensors, the flow meters, the tachometers and the global positioning system;
an operator display module located at the operator control station.

Abstract
An apparatus to monitor fuel, thrust, engine and vessel speed on marine vessels. Sensors measure the thrust forces developed by each of the ship'"'"'s propellers. The system compares the thrust produced to the gallons of fuel consumed by each system and prompts the vessel'"'"'s operator to make the proper throttle adjustment for each drive system to insure that the system with the best thrust to fuel ratio makes the largest contribution to the total thrust force required to maintain vessel speed.
