Influence of Tribotechnical Composition on Engine Performance

The tribotechnical coating helps to reduce the coefficient of friction and improve the fuel efficiency of the combustion engine. There are many different oil additives on the market, and in most cases the manufacturer gives little data on the consequences of their use in the engine, the specific results of such use, and does not disclose information on the mechanisms of action of these compositions. A separate issue is the study of the effect of these additives on the properties of engine oil and the mechanisms of its aging. The paper presents the results of using the tribological composition ArmActiv Moto 4 © in a single-cylinder diesel engine. The test program provided for the introduction of the additive according to the manufacturer's instructions and its subsequent change after the processing interval to obtain the results of the effect of the additive on the surface of engine parts. The results of measuring the power, torque and fuel consumption of both the base engine and the engine treated with the tribotechnical composition are presented. The research results showed that as a result of the influence of the additive, a certain decrease in fuel consumption and an increase in power indicators were obtained, most pronounced in the area of average revolutions.
