Patent ID: 7428890

Claim:
A fuel additive system for an internal combustion engine on-board a vessel, the system comprising: an internal combustion engine in fluid communication with a fuel storage tank through a fuel supply line and a fuel return line, the fuel storage tank includes a flow meter for measuring the flow of fuel from an outside source into the fuel storage tank, the fuel supply line transporting fuel from the fuel storage tank to the internal combustion engine and the fuel return line transporting unspent fuel from the internal combustion engine to the fuel storage tank; a reservoir for storing a fuel additive, the reservoir being in fluid communication with the internal combustion engine, wherein the reservoir for storing the fuel additive is in fluid communication with the fuel supply line disposed between the internal combustion engine and the fuel storage tank; and an injector for injecting the fuel additive into the internal combustion engine, the injector being in fluid communication with the reservoir and the internal combustion engine, wherein the internal combustion engine, the reservoir, and the injector are disposed on-board the vessel wherein the injector is coupled to the flow meter such that an appropriate amount of the fuel additive is automatically injected into the internal combustion engine upon the flow meter sensing an increase in the level of fuel in the fuel storage tank.
