Abstract:

The author presents Russian research results from factories and State Institutes. Micrometry, artificial incision, profilometry, and tracer methods of evaluating wear are all found to be useful, and plots are given. Plots of oil consumption, gas blow-by deformation, fuel consumption, effective power, and standard test rpm are among other techniques used in combination to evaluate engine condition. Quality control and tolerances of parts, volume uniformity among cylinders, mixture distribution uniformity, and cleanness of piston grooves are cited as the crucial non-operational factors.
