摘要： Starting a gaseous fuelled engine employing a pilot fuel at cold temperatures is challenging due to reduced ignitability and combustion efficiency of the fuel(s), and the increased viscosity of engine oil. A technique for starting a compression ignition, gaseous fuelled internal combustion engine employing a pilot fuel comprises determining one of a normal start condition and a cold start condition; during the normal start condition, introducing the pilot fuel into a combustion chamber of the internal combustion engine when the pilot fuel pressure rises above a first pressure; during the cold start condition, introducing the pilot fuel into the combustion chamber when the pilot fuel pressure rises above a second pressure that is higher than the first pressure; and selectively introducing the gaseous fuel into the combustion chamber.

摘要： 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.

摘要： Emission targets, such as NOx levels, for gaseous fuelled internal combustion engines that burn a gaseous fuel in a diffusion combustion mode are increasingly more challenging to achieve. A method of fuel injection for an internal combustion engine fuelled with a gaseous fuel comprises introducing a first amount of pilot fuel in a first stage of fuel injection; introducing a first amount of main fuel (the gaseous fuel) in a second stage of fuel injection; and introducing a second amount of main fuel in a third stage of fuel injection. The first and second amounts of main fuel contribute to load and speed demand of the internal combustion engine. Engine maps calibrated for different engine performance can be employed in different regions of the load and speed range of the engine. The engine maps are blended when the engine transitions between two regions; and momentary excursions into different regions do not change the engine calibration.
摘要翻译：对于在扩散燃烧模式中燃烧气体燃料的气态燃料内燃机的排放目标，例如NOx水平，越来越难以实现。用于燃料燃料的内燃机的燃料喷射方法包括在燃料喷射的第一阶段引入第一量的引燃燃料; 在燃料喷射的第二阶段引入第一量的主要燃料（气体燃料）; 以及在第三级燃料喷射中引入第二量的主燃料。第一和第二量的主要燃料有助于内燃机的负载和速度需求。针对不同发动机性能进行校准的发动机地图可用于发动机负载和速度范围的不同区域。当发动机在两个区域之间转换时，发动机地图混合; 不同地区的瞬间游览不会改变发动机校准。
