Method and apparatus for minimizing the fuel usage in an internal combustion engine
First Claim
1. An apparatus for minimizing the fuel usage in an internal combustion engine, wherein said engine is subject to varying loads, said engine having a fuel input and an air input and an exhaust output, said engine further including a governor means, said governor means for adjusting the flow of fuel to said engine as a function of load, said apparatus comprising:
- means for monitoring the combustibles in the exhaust output, said monitoring means including a condenser for condensing water contained in said exhaust output, said monitoring means further including a demister connected in line with said condenser for removing said condensed water, said monitoring means also including a bubbler connected in line with said demister for removing additional moisture from said exhaust output;
means for comparing the level of said combustibles to a predetermined value; and
means for adjusting the rate of fuel from said governor to said engine in a manner such that the level of combustibles equals said predetermined value, whereby said apparatus functions to fine tune the fuel supply to said engine thereby maximizing efficiency.

Abstract
An apparatus and method is disclosed for minimizing the fuel usage in an internal combustion engine. The subject invention is particularly adapted for use with an engine installation subject to varying loads and which includes a governor for varying fuel flow as a function of load. In operation, the combustibles in the exhaust gas of the engine is continuously monitored. The measured level of combustibles is then compared with a predetermined level corresponding to optimum efficiency. A controller is provided for varying the air/fuel ratio supplied to the engine for maximizing efficiency in correspondence with the preset level. By this arrangement, energy output is increased permitting the governor to further reduce fuel flow, thereby minimizing energy costs.
