Abstract:
A dual fuel engine powers a machine by burning natural gas and liquid diesel fuel. When operating in a low load mode, some of the engine cylinders are fueled with a high ratio of diesel/gas, and the remaining cylinders are unfueled. When operating in a high load mode, all of the engine cylinders are fueled with a low ratio of diesel/gas. When operating in a limp home mode, the fuel injectors are configured to inject only diesel fuel into all of the plurality of engine cylinders.
