. from these cards it must be remem-bered that the engine is a two cycle one. Compare with Fig. 50. horse-power at no load under the same conditions of lubri-cation, mainly because of the difference in the power Fig. 47.—B.H.P. tests. When themechanical efficiency of an enginehas to be measured,… … 144 THE INTERNAL COMBUSTION ENGINE absorbed in pumping. In the particular engine tested,the error from this cause in obtaining the indicated powerwould amount to about 5 per cent. The friction is sub-stantially constant from no load to full load, providedthat the temperature of the cylinder walls…
