Abstract
To determine eff ectiveness and feasibility of using an antifriction additive, the authors carried out comparative bench tests of an internal combustion engine VAZ-11194 No. 000094 of environmental class 5, with and without using an antifriction additive to Lukoil Genesis 5W-30 oil. The studies were carried out in accordance with GOST 14846 “Automotive Engines, Bench Test Methods”, UN Regulation No. 49 (emissions of carbon monoxide, hydrocarbons, nitrogen oxides with exhaust gases) and UN Regulation No.85 (performance indicators). During the tests, harmful substances with exhaust gases (CO, CH, NOx) emissions,engine power indicators and fuel consumption were evaluated. The tests were carried out according to presented method after 5, 50 and 100 hours of engine operation. The test results recorded an increase in power by 4.1%, in engine torque by 3.5…4.0% with a decrease in specifi c fuel consumption by 6…7% after 100 hours of engine operation with the use of an antifriction additive in engine oil. During the test period, harmful substances concentration in engine exhaust gases decreased: CO to 21.6%, CH to 18.3%, and NOx to 27.6%. A conclusion has been formulated on the eff ectiveness of using antifriction additives in terms of improving environmental, economic and power indicators of an internal combustion engine
