Abstract
A compression ignition dual fuel engine supplies natural gas fuel and liquid diesel fuel to each engine cylinder from a common fuel injector. Each fuel injector is fluidly connected to both a liquid fuel common rail and a gaseous fuel common rail. The engine includes a surplus gas system for capturing surplus gas, such as evaporated gas from the gaseous fuel supply and pressure control system, or left over pressurized natural gas produced by engine shut down. Rather than being vented to atmosphere, the surplus gas can be burned in the engine when operating conditions present burn opportunities.
