Preconditions of using the sectionally-continuous speed regulation in tractors development
Abstract
A method of sectionally-continuous tractor speed variation is examined, based on the rational choice of sufficiently short diapason of diesel compensative parameter. In these conditions power doesn’t decrease below nominal one and fuel economy improves by decrease of diesel rotation rate.

Theory of tractor operation in overload mode with enrichment of diesel air charge
Abstract
Parameters calculation technique of tractor operating in overload mode with diesel air charge enrichment with various hydrocarbonaceous activators (mineral diesel fuel, А-76, АИ-92 and АИ-95 petrols, ТС-1 kerosene, mixed rape-mineral and safflower-mineral fuels) is produced.

Probabilistic assessment of indicators of shafts and their joints corrosive fatigue resistance
Abstract
Results of fatigue tests of steel 45 samples in the air and in corrosive mediums simulating the atmospheric exposure on shafts and their joints are examined. Functions of corrosion coefficients are suggested and nomograms for the application of these coefficients’ probabilistic values in improved calculations of corrosive fatigue resistance of constructive elements are drawn.
