Research brake stands for testing small sized ice

Gusakov S.V., Epifanov I.V., Ukleikin V.E., Mahmoud Mohamed El Ghobashy El Hagar -.

Abstract

The urgency of a problem of creation of research stands for testing small sized IСE is defined by a wide circulation of engines of such type for mechanization of the manual skills, intended for use in structure of mobile vehicles and means of mechanization of auxiliary operations. During too time carrying out of tests of such type of engines at typical brake stands with the maximal rated power tested ICE 50-100 kW unfairly neither from the economic point of view, nor from the point of view of maintenance of comprehensible metrological characteristics. In article the basic approaches to create of the small sized stand basis of serially let out devices and known technological decisions are considered.

Problem questions of development of manufacture and consumption of biofuels in Russia

Ponomarev E.G., Gusakov S.V., Ponomarev A.A.

Abstract

Three basic problems facing to mankind in the 21st century are designated in the article: power engineering, foodstuffs and ecology. Limited nature of fossil energy sources, in particular for use as motor fuels for internal combustion engines, promotes expansion of different works in many countries on search, manufacture and application of alternative sources of energy, received from vegetative raw materials. The authors consider the situation concerning this problem in the Russian Federation, and offer actions for technologies delay liquidation efforts in bioenergetics area.
