Abstract
An ion sensing arrangement for a small internal combustion engine includes an ion sensor placed in the engine's combustion chamber to measure the conductivity of the combusted fuel-air mixture. Scaling circuitry, such as variable voltage divider circuitry, is connected to be in electrical communication with an output of the ion sensor. The scaling circuitry operates to adjust the output signal to a value appropriate for measurement. Preferably, the scaling circuitry adjusts the output signal based on a comparison with a reference value.
