Abstract : The patent relates to a unique apparatus in which a corrective electrical signal developed from the relative opaqueness of the products of combustion in a combustion process is used to regulate and control the input air-fuel ratio of the combustion process. The apparatus includes adjustable timing circuitry that intermittently activates and deactivates a summing amplifier. The summing amplifier provides an output signal that represents the difference between a preset potential and a potential proportional to the density of the smoke of the combustion process. The difference or error output signal of the summing amplifier is then used to control the input air-fuel ratio of the combustion process.
