    Abstract: A dual fuel engine is provided. The dual fuel engine includes an engine cylinder and a piston disposed within the engine cylinder. The dual fuel engine includes a cylinder head coupled to the engine cylinder and a fuel injector coupled to the cylinder head. The fuel injector is adapted to supply a first fuel to the engine cylinder. The dual fuel engine further includes a pre-combustion chamber coupled to the cylinder head at a predetermined distance from the fuel injector. The pre-combustion chamber is in fluid communication with the engine cylinder via at least one conduit and the pre-combustion chamber is adapted to receive a second fuel and an air mixture. The second fuel is different from the first fuel. The dual fuel engine further includes a spark plug structured and arranged within the pre-combustion chamber and the spark plug is adapted to ignite the second fuel within the pre-combustion chamber.

    Abstract: Apparatuses, systems and methods are disclosed including an internal combustion engine. The internal combustion engine can include an engine block defining a combustion cylinder and a crankcase, a piston moveable within the combustion cylinder; a cylinder head coupled to the engine block adjacent to and in fluid communication with the combustion cylinder, and a purge system. The purge system can be in fluid communication with the crankcase. The purge system can supply air to the crankcase and to the cylinder head. The purge system can comprise a valve cover coupled to the cylinder head, a breather coupled to the valve cover, and a fumes disposal line coupled with the breather. The fumes disposal line can transport fumes from the breather and away from the cylinder head.

    Abstract: In one aspect of the present disclosure, a pre-combustion chamber of an engine is disclosed. The pre-combustion chamber comprises a body having an external surface and an internal surface. The internal surface defines an ignition chamber. The pre-combustion chamber further comprises a first conduit adapted to supply a cold gas on the internal surface of the pre-combustion chamber. The pre-combustion chamber further comprises a second conduit adapted to supply a gaseous fuel into the pre-combustion chamber. The flow of the cold gas is regulated into the pre-combustion chamber to reduce temperature inside the pre-combustion chamber.
