Abstract
An ionizer for charging air in a motor vehicle with negative ions. The ionizer has an emitter with a pair of spaced electrodes, a high-voltage power supply, means connecting the power supply to the electrodes to apply a voltage differential across them and thereby ionize gas molecules adjacent the electrodes, and a sensor between the power supply and the electrodes for measuring current passing between the electrodes.
