There examined a problem of regulation of multicylinder diesel by variation of number of working cycles on regimes of low load and idle.

On an example of the boring rig the technique of search of algorithm of control by active dampers power bodies from a condition of the basic units of a machine design vibrations level limitation is considered. Technique is applicable to road-building, construction site and mine machines having similar dynamic structures.

The results of analysis of stress state of parts of gas-distribution mechanism of high-speed diesel.

Supply of an available housing by water of drinking quality is a strategic problem of the state in maintenance of vital, sanitary and hygienic safety of the population. At supply of the population by water important not only to solve problems of profitability of the enterprises of water supply and water removal but also to satisfy needs of social character.

The value of water of drinking quality is physiologically, socially and historically caused set of her useful properties from the point of view of suitability to satisfy food and household needs of vital necessity.

Research and estimation results of reliability of sanitary-engineering armature of internal waterpipe systems in residential buildings are presented. The attention is focused on fact, that operational reliability's indicators of sanitary-engineering armature of internal waterpipe systems in residential buildings can be defined on the basis of analysis, statistical data processing of registration and malfunctions in controller's record books and also by their consideration on the basis of reliability theory.

On an example of designing a head of small-sized diesel engine MD-8 the technique and results of the analysis of a thermal condition of a design with use of toolkit Solid Works and COSMOS Works are resulted. It is shown, that existing in Autodesk Inventor the concept of the organization and construction of assembly units is most convenient in internal-combustion engine design in view of great volume of changing analyzed parameters.
