“…However, after the design of the passive torsional damper is completed, the dynamic parameters, including damping and stiffness, will be fixed (Ngoc et al, 2018). It means that the deviation of processing and installation technology, the temperature-dependent performance decay, and other factors, may cause problems such as poor performance matching between the designed torsional dampers and crankshaft system and narrow tuning range (Sinyayski 2019). The damper based on magnetorheological fluid (MRF) intelligent material has the excellent characteristics of adjustable damping, wide dynamic range, fast response, and low power consumption (Deng et al, 2022) and is widely used in various intelligent vibration suppression applications (Ahamed et al, 2016;Lin and Jheng 2017;Krauze et al, 2018;Zhou et al, 2021), including crankshaft torsional vibration damper.…”

The purpose of this study was to solve the problem that the damping of rubber or silicone oil torsional dampers used in crankshafts is not adjustable and cannot effectively control torsional vibration at different resonant frequencies. Based on the controlled rheological properties of magnetorheological (MR) smart materials, this study designed a new type of variable damping MR torsional damper (MRTD) and proposed a semi-active control method to effectively control the torsional vibration of the crankshaft under multiple harmonic resonances. First, a mechanical model of the MRTD and a lumped parametric mass model of the crankshaft system were developed, and the resonance frequency harmonic range of the crankshaft system operation was determined by the torsional vibration characteristics analysis. Then a semi-active skyhook control method for the MRTD was proposed, and a joint control simulation analysis was performed using Amesim and Matlab software. The torsional vibration control effects of the crankshaft system with no damper, MRTD with different damping coefficients, and MRTD with skyhook control under acceleration and uniform speed conditions were comprehensively investigated. The simulation results indicated that the skyhook damping control significantly reduced the torsional vibration amplitude under both acceleration and uniform speed conditions, verifying the effectiveness of the skyhook-based control strategy for MRTD.

A zone model of the process of nitrogen oxides formation in a gas diesel cylinder when working on natural gas with exhaust gas recirculation is considered. The presented phenomenology of combustion of diesel fuel injected through a nozzle with five holes in methane-air mixture with products of exhaust gas recirculation in the combustion chamber of a diesel engine running on natural gas with recirculation of exhaust gases, where the behavior of processes and components distribution of nitrogen oxides is significantly different. For clarity, the selected zones of nitric oxide formation are schematically presented in the work as a graphic image.

The paper presents the results of the influence of the use of ethanol-fuel emulsion as a fuel on the performance of the combustion process and the soot formation processes of a 4CH 11,0/12,5 automotive diesel engine with a combustion chamber of the CNIDI type. The influence of the installation angle of advance of fuel injection on the maximum pressure and maximum temperature of the gases in the cylinder, as well as the mass concentration of soot particles in the nominal operating mode, is considered. Alternative fuel has a great influence on the content of soot particles in the combustion products, and their quantity, in turn, has a significant effect on the emissivity of the flame. And the thermal tension of the details of the cylinder-piston group depends on these indicators.
