Evaluation of the impact of anti friction additives on the economic, power and environmental performance of internal combustion engines

Abstract

Wear is one of the main factors that degrade the economic, power, and environmental performance of internal combustion engines. As well as reducing the reliability of their operation in general.Therefore, the purpose of this study is to define a method, physical and chemical, to increase the wear resistance of friction-pair parts, as well as to study its effect on economic, power, and environmental indicators. The internal combustion engine VAZ-11194 was used as a test object. To remove economic, capacity, and environmental indicators, we used an electric brake stand with induction brake FROUDE AG-150, installing a gas analysis AVL CEB-11, and a DFL-1 piston fuel flow meter. Test results were recorded after the engine had been running for 5, 50,100 hours. To evaluate the effect of the anti-friction additive, the tests were carried out in two stages (without the anti-friction additive and with the addition to the oil system). As a result of adding an additive, the torque (MT) increased by 30% on average, the power (Ne) increased by 4.1% on average, specific fuel consumption (SFC) decreased by 7.0% and emissions of harmful substances in engine exhaust gases during the test period decreased by an average of 20%. The results obtained indicate the effectiveness of the additive. In addition to improving performance indicators, it was noted that during the test period, there were no interruptions or failures in the operation of the engine, and at the end of the tests, there wereno defects (signs of friction, signs of wear, etc.) in the friction-pair parts. The decrease in the effectiveness of the anti-friction additive is minimal and amounts to about 1% per 100 hours of operation.
