Abstract
A stream of water or a water-methanol mixture is injected into the induction passage of a spark ignition internal combustion engine, and a probe disposed in the induction passage is contacted by the stream to sense when the density of the engine charge can be increased, the air-fuel ratio of the engine charge can be leaned and the timing of ignition of the engine charge can be advanced beyond normal operating ranges.
