摘要:针对12V190型天然气发动机定转速突加载响应性能较差,不能满足油田工作要求的问题,利用GT-Power软件建立了一维仿真模型,研究了增压器转动惯量、进排气管容积、增压系统型式、发动机负载转动惯量对该天然气发动机突加载响应性能的影响。根据研究结果对该发动机增压系统进行了改进设计,同时提高了发动机负载转动惯量,使其瞬态响应性能有所提高,满足油田钻井作业的要求。

Abstract:The poor transient response performance of 12V190 natural gas engine made it unable to meet the requirements of the oil-drilling work. The simulation model of 12V190 natural gas engine was built using GT-Power and factors which influence the transient response performance such as the rotary inertia of turbocharger, the volume of intake and exhaust pipe, the type of turbocharging system, and the rotary inertia of engine shaft were studied. The turbocharging system was improved and the rotary inertia of engine shaft was increased in accordance with the results of the research. The transient response performance of 12V190 natural gas engine was improved which made it able to meet the requirements of the oil-drilling work.
Key words:  natural gas engine  transient response  pulse turbocharging  rotary inertia
