Abstract

It is very important to know the hydrocarbon fuel concentration near the spark plug. The possibility of the concentration measurement near the spark plug using in-situ IR absorption method was presented. The fuel concentration near the spark plug was measured using an optical sensor with sapphire rods. A new optical sensor with double-pass measurement length was developed to increase the measurement accuracy. The light source with wavelength of 3.392 μm was introduced into an optical fiber and guided to a spark plug. This optical sensor was constructed by modifying a commercially available instrumented spark plug. Original is an abstract.
