Precision fuel additive system
First Claim
1. A liquid additive dosing device comprising:
- a. a liquid additive tank comprising a fill tube, one or a plurality of baffle plates, an outlet port, and a relief tube, said relief tube further comprising an inlet end and an outlet end, said outlet end of said relief tube being located above said outlet port and inside said additive tank,b. an electrically controlled cam driven dosing pump,c. an electronic input device containing a timing circuit for starting and stopping said dosing pump,d. and a liquid additive filter assembly upstream of said dosing pump, whereby said input device starts or stops said dosing pump based on an entering volume of liquid fuel to be diluted to said input device to deliver a corresponding volume of a liquid additive to a fuel tank of a vehicle, or liquid fueled generator.

Abstract
A precision additive dosing device comprising a liquid additive tank, dosing pump, filter, electric actuator, and pump control unit. Upon completion of fueling, the control unit is input with the corresponding volume of fuel just delivered. The pump starts until a time is reached that achieves the correct blend of additive for the fuel. The dosing pump delivers a constant volume of additive with time being the only variable to achieve the correct ratio of additive to fuel. Operation of the pump may be delayed or the time of pump operation may be increased during low ambient temperatures by the pump control circuit. Additionally, a heater may be used to heat the additive in similarly low temperatures.
