Abstract
The present disclosure relates to a combustion chamber of a diesel engine, which has a recessed combustion bowl to mix fuel injected from an injector with air, the combustion chamber including: a cylinder head which has the injector mounted thereto and is positioned at an upper side of the combustion bowl; a cylinder block which is positioned at a lower side of the cylinder head; and a piston which moves upward and downward in the cylinder block and faces the cylinder head, in which a plurality of radial inducers is provided on a bottom surface of the cylinder head around the injector.
Claims16
A combustion chamber of a diesel engine, which has a recessed combustion bowl to mix fuel injected from an injector with air, the combustion chamber comprising:
- a cylinder head which has the injector disposed therein and is positioned at an upper side of the combustion bowl;
- a cylinder block which is positioned at a lower side of the cylinder head;
- and
- a piston which moves upward and downward in the cylinder block and faces the cylinder head,
- wherein a plurality of radial inducers is provided on a bottom surface of the cylinder head around the injector, and
- wherein the radial inducers include a plurality of main inducers and a plurality of sub-inducers, each of the plurality of sub-inducers is disposed between two of the main inducers and has a length shorter than a length of a main inducer of the main inducers.
A combustion chamber of a diesel engine, which has a recessed combustion bowl to mix fuel injected from an injector with air, the combustion chamber comprising:
- a cylinder head which has the injector disposed therein and is positioned at an upper side of the combustion bowl;
- a cylinder block which is positioned at a lower side of the cylinder head;
- and
- a piston which moves upward and downward in the cylinder block and faces the cylinder head,
- wherein a plurality of radial inducers protrudes from a bottom surface of the cylinder head around the injector towards the combustion bowl,
- wherein the plurality of radial inducers is formed in a spiral shape,
- wherein at least a part of a squish flow and a part of a swirl flow are guided toward a center of the injector during a process of compressing the combustion chamber and joined to each other by the radial inducers,
- wherein the radial inducers include a plurality of main inducers and a plurality of sub-inducers, and
- wherein each of the sub-inducers is disposed between two of the main inducers and has a length shorter than a length of a main inducer of the main inducers.
