This patent describes improvement in combination with a Stirling engine having an air-fuel ratio control and an exhaust gas emission outlet. The improvement comprises an oxygen sensor in communication with the exhaust gas emission outlet for generating an output signal representative of the oxygen content in the outlet; a sensor signal conditioning unit for adapting the output signal to a conditioned input signal for a microprocessor; and a microprocessor controlled pilot for adjusting the air-fuel control in response to the control input signal.
