    • Engines fuelled with gaseous fuel stored in liquefied form comprise different strategies and controls for managing gaseous fuel compared to other systems, previously resulting in an ad hoc arrangements of controllers. An engine control apparatus comprises an internal combustion engine fuelled with a gaseous fuel stored in liquefied form and a control unit programmed with a fuel system module, for monitoring gaseous fuel pressure and actuating a fuel injection apparatus for introducing gaseous fuel into a combustion chamber, and a liquefied gaseous fuel module, for monitoring the quantity of liquefied gaseous fuel remaining in a storage vessel and controlling a pumping apparatus that pumps liquefied gaseous fuel from the storage vessel to a vaporizer. The fuel system control module and the liquefied gaseous fuel control module cooperate to introduce gaseous fuel in the combustion chamber at a predetermined pressure as a function of engine operating conditions.
    • 以液化形式存储的气体燃料燃料的发动机与其他系统相比较,包括用于管理气体燃料的不同策略和控制措施,以前导致控制器的临时安排。 一种发动机控制装置,包括用液化燃料储存的气体燃料燃料的内燃机和用燃料系统模块编程的控制单元,用于监测气体燃料压力并致动用于将气体燃料引入燃烧室的燃料喷射装置,以及 液化气态燃料模块,用于监测储存容器中残留的液化气体的量,并控制将液化的气态燃料从储存容器泵送到汽化器的泵送装置。 燃料系统控制模块和液化气体燃料控制模块协作以随着发动机操作条件的函数以预定的压力将气体燃料引入燃烧室。
