Opis:
This work covers the pollution of the atmosphere during the work of the Mikhailovsky Mining and Refining Facility which is located within 100 km from the city of Kursk, in the city of Zheleznogorsk. Over the past few years in the whole world, the anthropogenic activity, connected mainly with the locations of mineral production and those of mineral treatment and processing, has become increasingly dangerous for the natural environment. Resource development in open pits causes the formation of inorganic dust. The dust is released into the atmosphere at all stages of the enterprise’s technical process. The principal sources generating inorganic dust during open mining of iron deposits include: blasting operations in an open pit, the work of transfer points, the enrichment process at a factory, pellet firing as well as dusting from the surfaces of stock dumps and dry tailings beaches.

Opis:
The mathematical model for calculating the response time of the compression ratio of the mechanism for compression ratio changing (MCRC) is presented in this article. This revealed the influence of various engine factors with the connecting rod and crank mechanism (CRCM) on the operation of the MCRC (for example, the rate of the compression ratio change). The results of the study of the operation of the MCRC indicate a strong influence of the values (relative area of flow passage of channels) and р (pressure) on the response time τ in the field of their small values. This indicates that with insignificant changes of the area of flow passage of channel of the hydraulic lock and the minute oil pressure in the cavities, a significant response rate of the MCRC is ensured. The results demonstrate the possibility of speedy compression ratio change in the engine with the MCRC. Calculation studies showed that the mechanism full operation occurs quickly (0.02 s per unit εx), which indicates the expediency of using such a high-pressure pump in a four-stroke gasoline engine with CRCM. The mechanism movable body complete movement (S = 4 mm) at the oil temperature in the hydraulic system of 45°C and pressure on the body of p = 60 bar are stated to occur for 0.2 s.
