摘　　要：井下工作环境中存在一定浓度瓦斯气体,国三防爆柴油机在运行过程中吸入一定浓度瓦斯气体会造成转速扭矩波动,如何波动,在甲烷浓度到达多少的情况下波动,是否会被扭矩的波动压熄火都需要验证以确保极限状态下的安全。本文将以实际防爆柴油机为样品,对井下不同浓度甲烷气体进行环境模拟,在相同测试工况下进行对比研究。In the working environment of the national three explosion-proof diesel engine,it is possible that the diesel engine inhales a certain concentration of gas.Will the inhalation of gas cause the fluctuation of the speed and torque?Verification is required to ensure safety under extreme conditions.In this paper,the actual explosion-proof diesel engine will be used as a sample to simulate the environment of different concentrations of methane gas in the well,and conduct a comparative study under the same working conditions.
