Abstract:
A method of operating an engine assembly having a cylinder assembly which defines a combustion chamber, comprising the steps of:performing an intake stroke of the cylinder assembly;advancing a conditioning fuel into the combustion chamber during the intake stroke performing step;advancing a gaseous fuel into the combustion chamber during the intake stroke performing step;performing a compression stroke of the cylinder assembly after the intake stroke performing step;advancing a pilot fuel into the combustion chamber during the compression stroke performing step; andcombusting the pilot fuel in the combustion chamber during the compression stroke performing step so as to ignite the conditioning fuel and the gaseous fuel,whereby 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.
