Theoretical research and maintenance of electro hydraulically controlled injectors
Published 2023-01-01“…Nowadays the part of the diesel engines for KamAZ-740 cars are operated with fuel equipment, in which the injectors have hydro mechanical control. Their main disadvantage is the low fuel pressure in front of the injector openings (less than 60 MPa) and the lack of fuel supply control.The use of injectors with electro hydraulic control (EHC) increases the pressure in the injector cavity up to 250 MPa and control the fuel injection process. …”

Formation and controlling of Type-D inclusions in bearing steel
Published 2018-12-01“…There are strict requirements for non-metallic inclusions in bearing steel, especially for Type-D inclusions.To analyze the formation mechanism of Type-D inclusions in high-frequency detection defects of GCr15 bearing steel bar sample in domestic steel plant and give the effective controlling measure, the inclusion evolution in bearing steel production process before and after optimization was investigated by ASPEX automatic scanning electron microscope.The results show that, the main formation mechanism of calcium aluminate Type-D inclusions present in the original process includes two aspects:one is the high basicity of refining slag, resulting in the high Ca O activity in slag.The other is the strong stirring in vacuum degassing (VD) process, providing good kinetic conditions for slag-steel reactions.The bearing steel production process is optimized from the basicity of refining slag and the vacuum degree of VD process.After optimization, the inclusions change from calcium aluminate to spinel type, and the formation of Type-D inclusions in bearing steel is reduced.Meanwhile, the high cleanliness of bearing steel is maintained.…”

Structure controlled enhanced photocatalytic activity of polyaniline (PANI)
Published 2025-02-01“…Hence, we attempted to synthesize polyaniline with enhanced crystallinity by controlling various process parameters. As process parameters, the molarity of HCl viz. 0.1M, 0.5M, 1.0M, 2.0M, and 6.0M; and precipitation (polymerization) temperature viz. 25 °C (room temperature, RT) and 0 °C (using ice) were investigated to synthesize PANI with maximum crystallinity to find optimum synthesis conditions. …”
