dc.descriptionDetermining the effect of anti-friction additive on the power of mechanical losses in a rotary piston engine / O. Mytrofanov, A. Proskurin, A. Poznanskyi, O. Zivenko // Eastern-European Journal of Enterprise Technologies. – 2023. – Vol. 4, No. 1 (124). – P. 28–34.
dc.description.abstract1Experimental studies of the effect of adding the anti¬friction additive Multi-Tech-Conditioner to lubricating oil on the power of mechanical losses of a rotary pis¬ton engine were carried out, the purpose of which was to reduce the cost of potential energy of a compressed working fluid to overcome friction forces. The experimen¬tal data obtained make it possible to estimate the value of irretrievable losses of the available power of a rota¬ry piston engine at the stage of its design and operation. Experimentally, a positive effect of the addition of the Multi-Tech-Conditioner antifriction additive to lubricating oil on the change in the power of mechanical losses of the engine was established, which was reflected in a decrease in total losses over the entire operational range of change in the rotor speed by 11.8 %. As a result of the research, it was determined that the losses for pumping strokes (gas exchange) in a rota¬ry piston engine amount to 31.6 % of the total power of mechanical losses. An assessment was made of change in the mechanical efficiency of a rotary piston engine with a hinged-cam mechanism for converting motion under the condi¬tions of applying an antifriction additive to lubricating oil. It has been established that the addition of the Multi-Tech-Conditioner additive to the lubricating oil in a ratio of 1:14 makes it possible to increase the mechanical efficiency of a rotary piston engine depend¬ing on the speed by 3.8–5.5 % for all operating pres¬sures in the inlet receiver. Based on the generalization and systematization of the obtained experimental data on the use of the Multi- Tech-Conditioner additive, the most rational operating ranges of a new design rotary piston engine were iden¬tified. The maximum mechanical efficiency of a rotary piston engine is achieved in the load range of 65...75 % of the rated power, and the speed range is 63...70 %.
