Optimal parameters calculation of fire-resistant shield for fire-prevention blind and shelters
For increase of fire-prevention level of buildings, structures and external technological equipment fire-prevention blind and shelters are designed. Fire-resistant shield is protective element of fire-prevention blind and shelters. To describe physical processes in the shied in fire and to determine fire-resistance, mathematical model is developed. To calculate shield optimal parameters, algorithm and program are developed. Calculation results are presented.
Keywords: fire-prevention barrier, fire-prevention blind, fire-prevention shelter, fire-resistant shield, fire-resistance, fire safety, mathematical model, combined way for increase of construction fire-resistance.

Regulation of Working Process of Diesel by Variation of Physical - Chemical Properties of Fuel
There presented some results of experimental research of opportunities to influence for working process of diesel by variation of physical - chemical properties of fuel during working of diesel. This effect is achieved by mixing diesel fuel with different alternative fuels and other inflammable and uninflammable additives. Process of mixing or blending of components of fuel takes place into canals of injector by means of special check - valve near the injector - the valve of regulation of pressure initial (RPI) of fuel. There presented systematization of problems, which may be solved by this method. Method is named "physical - chemical regulation" - PhChR.
Keywords: diesel, physical-chemical regulation, alternative fuels.

Outlooks of usage gas-bottle of motor engines with the board oscillator of synthesizing-gas
The article deals with the analysis of dynamics of variation of the requirements to composition of exhaust gas of internal combustion engines and the measures on an abatement of poisonous reductants in their composition. As a key problem of improving the ecological and economical ations of internal combustion engines the ways of applying of alternate combustibles, in particular of natural gas of methane and component of synthesizing-gas (hydrogen inclusive of a mixture) to the main (basic) combustible are concerned. The results characteristics of trials of the automobile "Gazelle" the different fuels are given here.
Keywords: gas-bottle automobiles alternate combustibles, board oscillator of synthesizing-gas, hydrogen inclusive a mixture (synthesizing-gas), mixtures of gaseous fuels, operation indices of operation of the automobile.

Liquefied Hydrocarbon Gases: Urgency of Utilization and Means of Accounting
The article presents analysis of urgency of liquefied hydrocarbon gases (LHG) utilization in Russia and all over the world. The main physicochemical properties of LHG, that staff of LHG facilities must know, are considered. The recommendations on minimization of methodical faults of LHG commercial accounting in the process of filling-overspill operations are given. The long-term special-purpose reference points of Russia economic policy on diversification of goods structure of power carriers export are given.
Keywords: liquefied hydrocarbon gases (LHG), density, volume and mass of LHG, LHG accounting.

The new concept of application of spirits as motor fuel
The modern methodology of application of spirits as motor fuel is stated. The parameter of a hotbed effect of fuel is offered. Results of tests of engines are stated at work on spirits. The mechanism of formation{education} of soot is stated at use of spirits. Methods of calculation of parameters of systems of submission of spirits are resulted{brought}. Strategy of normalization of emissions ÑÎ2 is resulted{brought}. Application of spirits reduces emission of hotbed gas in two with superfluous time. The concept of application of spirits in petrol engines and diesel engines is developed.
Keywords: biofuel, a parameter of a hotbed effect, hotbed gases, methyl and ethyl spirits, normalization of hotbed gases, efficiency of biofuel.

Application of thermal pumps for central heating at extraction and biogas recycling on ranges of firm household waste
In article problems of safe operation of ranges for a burial place of a firm household waste are considered. Danger at storage of a firm household waste on ranges, in particular, is connected with the uncontrollable issue of biogas connected with biological decomposition of organic substance. Production process of extraction and biogas recycling on ranges will allow to solve this problem. Complex problems of effective recycling of biogas as fuel on ranges for the purpose of central heating and reception of electric energy are considered. Application of thermal pumps allows to raise the general power efficiency of the technological scheme. Alternative ways of increase of power efficiency of technology of recycling of energy of biogas are considered also.
Keywords: biogas, ground, wastes, heat-exchange, thermal pump, renewable energy source, evaporator, compressor, condenser.

The methodological aspects of vehicle environmental safety improvement
The methodological aspects of vehicle environmental safety improvement are discussed. It is essential to harmonize the nomenclature of harmful components in the motor vehicle emission for regulation of its specific values and maximum concentration limits in the city atmosphere. The significance of air purification in the vehicle cab is demonstrated.
Keywords: vehicle, emission of air pollutants, specific emission, harmful components, European emission standards, oxides of nitrogen, nitrogen dioxide, dust.
