Abstract
Official abstract text for this publication.
A dual fuel engine is provided. The dual fuel engine includes an engine cylinder that is adapted to house a piston. A cylinder head is coupled with the engine cylinder. An inlet valve is adapted to inject a second fuel into the engine cylinder. A pre-combustion chamber is adapted to be coupled within the cylinder head to receive a first fuel via a micro-pilot fuel injector. As piston moves towards a top dead center pushing a portion of the second fuel into the pre-combustion chamber via a communication channel, the piston compresses the portion of the second fuel and the first fuel in the pre-combustion chamber for igniting the first fuel and combusting the second fuel. This generates a combustion flame. The pre-combustion chamber is adapted to allow the combustion flame to propagate from the pre-combustion chamber to the engine cylinder via the communication channel.
First claim
Opening claim text (preview).
What is claimed is: 1 . A dual fuel engine comprising: an engine cylinder adapted to house a piston; a cylinder head coupled with the engine cylinder; an inlet valve adapted to inject a second fuel into the engine cylinder; and a pre-combustion chamber adapted to be coupled within the cylinder head to receive a first fuel, the pre-combustion chamber being in fluid communication with the engine cylinder via at least one communication channel; wherein the pre-combustion chamber includes a micro-pilot fuel injector to inject the first fuel into the pre-combustion chamber to initiate combustion; wherein the dual fuel engine is adapted to move the piston from a bottom dead center to a top dead center, the piston pushes a portion of the second fuel into the pre-combustion chamber and compresses the portion of the second fuel and the first fuel in the pre-combustion chamber for igniting the first fuel and combusting the second fuel; wherein the pre-combustion chamber is adapted to allow a combustion flame to propagate from the pre-combustion chamber to the engine cylinder via the at least one communication channel, and moving the piston from the top dead center to the bottom dead center.
