Abstract:

In order to study the impact of the intake and exhaust anti-explosion systems for mine-engine performance, this paper takes a certain type of mine-diesel as the prototype to test the external characteristic of mine-engine in increasing the intake and exhaust anti-explosion system before and after of both states， the test results showed that under increasing the intake and exhaust anti-explosion system,diesel engine rated power declined by 8.6 percent, a decrease of 8.1 percent of maximum torque, minimum fuel consumption rate increased by 14%, the maximum exhaust temperature of 12%. The results show that after increasing intake and exhaust explosion system, intake and exhaust resistance of mine-engine increases, air intake pressure decreases, the exhaust back pressure increases, air consumption reduces, power and torque reduces too, power performance drops , fuel consumption increases, economic performance becomes poor, the exhaust gas temperature rises.
