ABSTRACT:
A method of operating an engine assembly having a cylinder assembly which defines a combustion chamber is disclosed. The method includes the steps of performing an intake stroke of the cylinder assembly and advancing a conditioning fuel into the combustion chamber during the intake stroke performing step. The method further includes the steps of advancing a gaseous fuel into the combustion chamber during the intake stroke performing step and performing a compression stroke of the cylinder assembly after the intake stroke performing step. The method yet further includes the steps of advancing a pilot fuel into the combustion chamber during the compression stroke performing step and combusting the pilot fuel in the combustion chamber during the compression stroke performing step so as to ignite the conditioning fuel and the gaseous fuel. The gaseous fuel and the conditioning fuel are mixed in the combustion chamber prior to the pilot fuel advancing step so as to facilitate ignition of the gaseous fuel in the combustion chamber.
