FILTRATION OF COMBUSTION AIR AND COOLING AIR OF INTERNAL COMBUSTION ENGINES AND COOLING AIR FOR ELECTRIC MACHINERY ON MOTIVE POWER UNITS. PART B: INFILTRATION OF SNOW. SUPPLEMENTARY ENQUIRY (WINTER 1962/63)

In the conclusions of Report B 67/B "Infiltration of snow", June 1963 edition, the Rapporteur proposed that the experience gained by the Administrations in the severe winter of 1962/1963 (heavy snowfall at extremely low temperatures) should be collected by means of a supplementary enquiry. The present report contains the results of this enquiry. As to the behaviour of the air-gratings and air-filters relative to the infiltration of snow, the data compiled in the first report were confirmed. The extreme weather conditions in the winter of 1962/1963 led, however, to break-downs of motive power units, which, for the major part, require measures in addition to the mere installation of air-gratings and filters. Technical and operational improvements introduced by the Administrations are described in the report. The proposal of ORE for a further study of the question "winter resistant motive power units" has been incorporated in the Chapter "Conclusions".
