COMBUSTION CHAMBER WITH DUCTS FOR INTERNAL COMBUSTION ENGINES

摘要

An internal combustion engine is provided. The internal combustion engine includes an engine cylinder, a piston, a cylinder head, a combustion chamber, and a fuel injector. The cylinder head has a depression of predefined shape such that an effective width of the depression of cylinder head is greater than a diameter of the engine cylinder. The combustion chamber is defined as an enclosure between the depression of the cylinder head and a crown of the piston. The fuel injector is adapted to supply fuel to the combustion chamber via a number of orifices. In an alternate embodiment, the combustion chamber is provided with a number of ducts adapted to provide a passage to the fuel exiting from the orifices. The ducts extend at a predefined angle with an axis of the engine cylinder to facilitate injection of the fuel towards the depression of the cylinder head within the combustion chamber.
