Forecast Evaluation of Possible Values of Fuel Injection Pressure of Common Rail System

Abstract

The summary summarizes our own long-term experimental data from field and laboratory experiments to study the functional state of plants under the short-term and long-term effects of liquid fertilizer stimulating compounds (ZhUSS) developed at Kazan State Agrarian University as a result of interdisciplinary studies. The multifunctionality of their effect on plants has been established: stimulation of growth processes, activation of protective enzymes of antioxidant protection of cells, photosynthetic and absorption activity, antistress effect, etc. The use of these drugs is effective for two and three times exposure. The positive effects of ZhUSS are prolonged over time due to the concentration in the seeds of plants of the trace elements that make up the ZhUSS. The multifunctional mechanism of their influence leads to the activation of plant production processes, an increase in the yield and quality of agricultural products in connection with the effect of biofortification. An integrated circuit has been developed for the multifunctionality of the action of ZhUSS preparations. Based on convergent knowledge (interdisciplinary research) of agrochemistry, chemistry and physiology and biochemistry of plants, Kazan State Agrarian University created effective chelated micronutrient fertilizers of the ZhUSS brand, recommended for widespread use on soils poor in microelement composition, with the aim of increasing crop yields and crop quality in different climatic conditions due to the effect of biofortification. The use of these drugs is effective for two and three times the exposure.

Possible Measures to Extend the Service Life of Diesel Fuel Pump Main Components

“…Функциональную способность пар трений системы питания дизелей определяют значения параметров, характеризующих техническое состояние топливной аппаратуры. То есть качество рабочего процесса системы питания в основном зависит от того, как и когда подается топливо, в каком количестве и под каким давлением оно впрыскивается в камеру сгорания [1,2,3]. В процессе эксплуатации состояние пар трений системы питания ухудшается, сопрягаемые поверхности становятся неоднородными, гидравлическая плотность снижается вследствие истирания, в результате чего цикловая подача топлива перестает обеспечиваться в необходимом объеме [4,5].…”
