Estimation of Operation Efficiency of Machine-Tractor Units Equipped with Constant Power Engines.

摘要

ABSTRACT Numerous published data evidence positive influence of the length of constant power range on power and technical-economical properties of internal combustion engine (ICE) and total operating unit, but the length of constant power range is determined by external regulatory characteristic of ICE which is plotted by consecutive load increase from zero to total load.The article attempts to estimate the deformation rate of constant power range at alternative pattern of external load.
