电控柴油-天然气（双燃料）发动机装车性能试验研究

摘要

In this paper，the onboard test performances of an electronically controled diesel-natural gas（double fuel）engine are investigated．Test results show that the onboard performances reach that of the former engine．Moreover，it has been slightly improved compared with the former in accelerating smoke，noises，and accelerating characteristics．Fuel substitution rate in cities reaches 67％．%本文主要对电控柴油-天然气（双燃料）发动机的装车性能进行了试验研究，实验结果表明：改装机能达到原机性能并在自由加速烟度、噪声、加速性等方面比原机略有改善，城市工况的燃料替代率较高。
