This paper presents comparative experimental study’s results of ethanol-diesel fuel blends made effects on operational properties of a high-pressure fuel pump of a common rail injection system. The two identical fuel injection systems mounted on a test bed of the fuel injection pumps were prepared for the experimental durability tests. The lubricity properties of ethanol-diesel fuel blends E10 and E20 blends were studied using a four-ball tribometer. The test results showed that long-term (about 100 hours) using of ethanol-diesel blends produced a negative effect on the durability of the high-pressure fuel pump. Due to the wear of plunger-barrel units the decrease in the fuel delivery rate occurred of about 39% after the 100 h of continuous operation with ethanol-diesel fuel blends. The average friction coefficients of ethanol-diesel fuel blend E10 was lower than that of the normal diesel fuel. After the 100 hours of operation with ethanoldiesel fuel blend E10, the measured wear scar diameter was 10% higher than that of a fossil diesel fuel.
