Abstract
A method of operating an engine assembly having a cylinder assembly which defines a combustion chamber is disclosed. The cylinder assembly includes an engine block having a piston cylinder defined therein, a piston which translates in the piston cylinder, and a crankshaft which is mechanically coupled to the piston. The method includes the steps of performing an intake stroke of the engine assembly and advancing gaseous fuel and air into the combustion chamber during the intake stroke performing step. The method further includes the step of performing a compression stroke of the engine assembly after the is intake stroke performing step. The method yet further includes the step of injecting a pilot fuel into the combustion chamber during the compression stroke while the crankshaft is positioned at about X degrees before top dead center, wherein 21.0<X<28.0. The method further includes the step of combusting the pilot fuel in the combustion chamber during the compression stroke performing step so as to ignite the gaseous fuel. An engine assembly is also disclosed.
