New technologies of the diesel engine make the soot content in the lubricant highly increase.According to the ASTM standards,Mack T-9 engine bench test is used to evaluate the wear of the diesel engine due to the soot.But the evaluation time is more than 500 h,which is not conducive to the rapid screening of diesel engine oil.In order to improve the screen efficiency of the developing diesel engine oils,the SRV simulation test was used to evaluate the antiwear property of the lubricants after Mack T-9 bench test.The relativity between the two kinds of test methods was studied.Testing results indicate that the SRV lubricants extreme pressure (EP) test of NB/SH/T08822014 and the Mack T-9 engine bench test have a good relativity in the testing results when diesel engine oils containing the carbon black similar in structure to the soot are used in the SRV tests.This method can predict the oil sample test results of Mack T-9 engine bench.
