摘　　要：针对双燃料发动机在中、低负荷时HC和CO排放较高的缺点,采用了进气节流和废气再循环等措施来降低HC和CO。试验结果证明,采用这些措施是有效的,特别是对于降低中、低负荷时的HC排放更是效果显著。The faults of natural gas/diesel dual fuel engines have been popularized in many cities of China. In this paper, throttle and exhaust gas recirculation (EGR) have been adopted to reduce the emissions of HC&CO from dualfuel engines. The test results showed that it is useful to reduce the emissions of HC&CO by throttle and EGR. Especially, it is effective for dualfuel engines in low and middle load.
