Study on Intake and Exhaust Flame Proof System Affected to Performance of Mine Diesel Engine

In order to study the intake and exhaust flame proof system affected to the performances of the diesel engine,based on a mine diesel engine as a test prototype,external features tests were conducted on the test prototype before and after applied with the intake and exhaust flame proof system. The test results showed that after the intake and exhaust flame proof system applied,the rated power of the diesel engine was reduced by 8. 6%,the max torque was reduced by 8. 1%,a min oil consumption rate was increased by 14% and a max exhaust temperature was increased by 12%. The study results showed that after the intake and exhaust flame proof system applied,the intake and exhaust resistance of the mine diesel engine was increased,the intake pressure was reduced,the exhaust back pressure was increased,the air consumption was reduced,the power and torque were reduced,the power performances were reduced,the fuel oil consumption rate was increased,the economic performances were became poor and the exhaust temperature was increased.
