Fuel additive injection system
First Claim
1. A fuel additive injection system for adding fuel additive to a quantity of fuel stored in at least one fuel tank, said fuel tank being one of carried onboard and operably connected to one of a motor truck, a marine vessel and a stationary engine-driven apparatus, said injection system including:
- an additive supply tank for containing a quantity of fluid fuel additive;
a conduit interconnecting said additive supply tank with said fuel tank and including a remotely controllable shut-off valve interposed therein;
a flowmeter interposed in said conduit; and
a controller operably connected to said flowmeter and said shut-off valve, said controller including a programmable microcontroller, a visual display and a user interface to said microcontroller for causing said system to enter a predetermined state, one of said states being the dispensing of a predetermined quantity of fuel additive from said additive supply tank to said fuel tank.

Abstract
A fuel additive injection system includes a fluid additive supply tank, a fluid additive quantity sensor, a flowmeter, remotely controllable valves and a controller including a microcontroller, a visual display and a keypad interface for establishing operation of the system to blend or inject a fuel additive for an internal combustion engine on a vehicle or a stationary apparatus. A quantity of a particular fuel additive to be injected may be selected based on a predetermined amount of fuel added to one or more fuel tanks. The system may keep records of fuel consumption and may utilize pressure air from a source driven by an engine or additive may be injected utilizing a motor driven pump as part of the additive injection system.
