Abstract

A gaseous fuel engine system includes a quick start fuel system having a pressurized gaseous fuel supply, a fuel feed conduit and a quick start fuel admission valve. The fuel feed conduit is coupled to an intake conduit for the engine at a downstream fuel admission location. A main fuel system is coupled to the intake conduit at an upstream fuel admission location. The quick start fuel admission valve is electrically actuated to admit a pressured gaseous fuel from the pressurized gaseous fuel supply for quick starting the gaseous fuel internal combustion engine. The quick start fuel may have a fuel composition different than a fuel composition of the main fuel.
