<p>1,099,886. Measuring oil consumption. DAIMLER-BENZ A.G. Nov. 4, 1966 [Nov. 6, 1965], No.49603/66. Heading G1R. In a method of or apparatus for measuring oil consumption an oil sump 1, such as that of an I.C. engine, is in open communication, through a pipe 3, with a vessel 2 provided with an overflow pipe 6 which maintains the oil levels 5, 4 constant and returns excess oil to a measuring vessel 7, having a surface area which is considerably smaller than the total surface areas at the levels 4, 5, from which oil is recirculated to the vessel 2 by a pump 9. The oil consumed in the sump 1 will cause a decrease in the level in vessel 7 causing a float 13 to actuate an indicator 14. In further embodiments any oil consumed is replenished from a finely graduated narrow-bore pipette, Fig. 2 (not shown) and the oil level is maintained constant by a photo-electric device, Fig. 3 (not shown).</p> |
