“…The deceleration of the rotor is carried out by covering this damper. It is experimentally necessary to determine the pre-burst modes when the air damper operates [16,23,24]. A damper was removed from the modernized accumulator and a brake device of the lubrication system of a KAMAZ vehicle and its finite element model was built, including 26,822 elements, 42,266 nodes, 3D elements, type-Tet10 (Fig.…”

“…The stochasticity of the loads causes a decrease in the pressure P and the Q feed rate of the lubricant, but this is followed by an instant increase in the temperature T of the TCR body and all its elements. This disadvantage-stochasticity-is eliminated in the practice of mechanical engineering by increasing the power reserve factor and torque [15][16][17], but on the other hand, high power and high torque reduce the efficiency of ICE use due to underloading [18]. Therefore, the problem of the TCR reliability is solved by scientific teams of universities and machine-building plants in other ways: improving the nodes of TCR [6,19]; new structural materials of their parts [1,3]; modernization of the lubrication system and oil supply channels to TCR bearings [2,5]; use of electric pumps [10], control valves and turbo-timers [11,12], various electronic and microprocessor control systems for the operation of the turbo system [17,18].…”

“…Surfacing is a phenomenon of the oscillatory process of the air flow with its essential limitation [7,20,22]. Since in the experimental part of the work it is intended to use a braking device in the form of an air dam, the factory equilibrium modes will be violated [16][17][18]. In this connection, it is required to simulate the operating modes of the damper and to study its characteristics.…”

The priority direction of the development of mechanical engineering is the increase in the energy saturation of the automobile and tractor fleet. One of the most effective ways of boosting modern engines is turbocharging and the use of turbochargers (TCR). However, along with a positive effect-boosting and increasing the power in the range of 5-50%, there is a significant drawback-a decrease in the engine reliability. The main reasons for this are: high stochastic load conditions, which is 10-150%, depending on the type of the work performed. The use of the hydraulic accumulator providing additional lubrication of the TCR rotor bearings predetermines an increase in the rotor run-out time by a factor of 1.5-2.5, and, correspondingly, an improvement in the design parameters of the accumulator. When connecting the brake device, with a simultaneous integrated application of the accumulator, the duration of the run-out of the TCR rotor is reduced by 30-40%. In this case, providing the accumulator with a standard accumulator lubrication of the rotor bearings enables to reduce the volume of the accumulator to 2.0-2.2 L and its dimensions in 1.2-1.5 times. But at the same time, there are surging phenomena of moving with a high-speed air flow. To prevent surging, it is necessary to study the spectrum of eigenfrequencies and the shape of the oscillations of a brake device damper. For this purpose, a classical experimental vibration setup was used and the first five resonance frequencies were determined.

“…Reducing energy consumption is possible through the use of alternative fuels, allowing to eliminate or reduce the consumption of fuels of oil origin [1,2]. The issues of improving fuel efficiency using alternative fuels and improving the design of internal combustion engines are widely covered in the works of Bystrov [3], Vedruchenko [4], Goncharov [5], Gritsenko [6,7], Gurevich [8], Kaydash [9], Kormilitsyn [10], Cookis [11,12], Lewis and Elbe [13], Martynenko [14], Sakulin [15], Smolin [16], Storozhev [17], Trelina [18], and other researchers. On the basis of the Mechanics and Technology Institute of the State Agrarian University of the Northern Trans-Ural region for several years, the authors of the article carried out research on the effect of water injection on fuel efficiency and environmental safety of diesel engines of the family 4F 11/12.5 [19,20].…”

The article presents the results of research to improve the fuel efficiency of the engine 4F 11/12.5 (D-240) using water injection. The relevance of the use of water (water vapor condensate) as an additive to hydrocarbon fuel is shown, which contributes to the increase in power and fuel efficiency in the operation of the internal combustion engine. It was experimentally established that the greatest increase in the effective power of a diesel engine 4F 11/12.5 (D-240) is observed when water is supplied in a volume equal to 27-32% of the volume of the cyclic supply of diesel fuel. It has been experimentally established that with an increase in the volume of supplied water, the temperature of the exhaust gases decreases, with an average intensity of about 1°C per 1% of the water supply. The greatest decrease in the temperature of the exhaust gases was noted at the maximum torque regime. The results of the studies showed a steady increase in the indicator pressure by an average of 18-22%. A decrease in the rigidity of the operation of the investigated engine is achieved, which is explained by a decrease in the rate of change in the indicator pressure (on average by 5-15%), in comparison with work on diesel fuel.

RESUMEN Los turbocargadores en la actualidad han demostrado ser imprescindibles en el campo automotriz por ser máquinas que se encargan de aumentar la potencia, reducir el consumo de combustible y generar menos dióxido de carbono en un motor de combustión interna. En este artículo se presenta el desarrollo de un modelo matemático en base a un plenum, con el propósito de obtener las características dinámicas del flujo másico que genera un turbocargador. Para cumplir con lo propuesto se fundamentó en el conocimiento teórico-práctico de las leyes y conceptos que conforman un turbocargador, dando como resultado la simulación de un modelo matemático utilizando la herramienta Simulink. Para el desarrollo del modelo matemático se utilizaron datos teóricos y de pruebas en régimen estable y dinámico, así como el comportamiento del plenum sometido al sistema de compresión. Este modelo planteado contribuirá a la comunidad científica a través de la obtención de las características entre la relación de compresión y el flujo de masa del compresor de un turbocargador, también, aportará en el futuro al campo de la detección y diagnósticos de fallos orientados a los turbocargadores vehiculares.
