Bombardier/Alco公司研制出新型火花点火式6缸煤气机,它在1200r/min时的额定功率为815kW,这种根据火花点火式双燃料发动机的30多年经验、以历史悠久的251型柴油机技术为基础而推出可燃用贫煤气的6-251SI型发动机(见图),把耐用的柴油机零部件与一些堪称当今最传的气体燃料发动机技术结合起来。当今“最佳的煤气机技术”意指空气与燃料的最佳控制和可能的最佳点火与燃烧。没有这些关键的因素则就不会有当今所需要的低NOx、低燃料消耗运行的发动机。对于Alco公司的成果,要在今后的二、三年现场试验中加以最终评定,燃而,最初的试验室试验结果却是很好的,在815kW的全负荷工况下,
Bombardier / Alco has developed a new spark-ignition six-cylinder gas engine with a rated power of 815 kW at 1200 r / min, based on more than 30 years of experience with spark-ignition dual-fuel engines and the historic 251 diesel technology Based on the introduction of a flammable, lean gas 6-251SI engine (see photo), combining durable diesel engine components with some of today’s most popular gas-fueled engine technologies. Today’s “best gas engine technology” means the best control of air and fuel and the best possible ignition and combustion. Without these key factors, there is no need for low NOx, low fuel consumption running engines that are required today. The results of the Alco company, to be finalized in the field test in the next two or three years, but the initial laboratory test results are very good at 815kW full load conditions,
