Summary:

The object of microwave diagnostics is to provide accurate, noninvasive measurements upon engine. This paper deals in particular with experiments performed upon the valves of a Buick V-6 engine. A microprocessor controlled data processing system is described that (1) collects and stores, in digital form, the microwave signal developed during several engine cycles (2) produces a very high resolution computer print out of the stored signal correlated with engine crank angle, and (3) outputs a printed analysis of every microwave resonance found in the signal. Exhaust valve motion produces a directly related shift in the crank angle position of a resonance. The magnitude of the shift in the TE111 mode resonance is 7 degrees for one cycle in the change of this valve. The maximum displacement of this valve into the cylinder is .200 inch. A displacement of .005 inch can be measured
