Abstract

To provide a sub-chamber device hardly affected by abrasion.SOLUTION: A sub-chamber device 1 for a cylinder of an internal combustion engine includes a main body section 3 for fixing a cylinder head 2 of the cylinder of the internal combustion engine to the sub-chamber device 1, and a nozzle section 4 connected to the main body section 3 and including a nozzle orifice 7. A sub-chamber combustion chamber 5 of the sub-chamber device 1 of the cylinder defined by the main body section 3 and the nozzle section 4 is connected to a main chamber combustion chamber 6 of the cylinder through the nozzle orifice 7. The nozzle section 4 and the main body section 3 are connected to the nozzle section 4 in a manner that it cannot be detached, and projected into the main chamber combustion chamber 6 over the cylinder head 2, so that in the sub-chamber device 1, the sub-chamber combustion chamber 5 and the main chamber combustion chamber 6 are separated from the main body section 3 at one side and from the nozzle section 4 at the other side in a region of a section 8 projected into the main chamber combustion chamber 6 in the sub-chamber device 1.SELECTED DRAWING: Figure 1

No. 5,958,015, a secondary chamber arrangement for a cylinder of an internal combustion engine is known. The sub-chamber apparatus disclosed in Patent Document 1 includes a main body section and a nozzle section. The body section serves to secure the auxiliary chamber arrangement to the cylinder head of the cylinder of the internal combustion engine. The nozzle section is connected to the main body section and comprises a nozzle orifice, and the auxiliary chamber combustion chamber of the auxiliary chamber device defined by the main body section and the nozzle section is connected to the main chamber combustion chamber via the nozzle orifice . This section of the subchamber arrangement is completely provided by the nozzle section, which projects into the main chamber combustion chamber by the nozzle section. The body section and the nozzle section are connected to one another via at least one lock.

摩耗の影響を受けにくい副室装置が必要とされている。ここから出発して、本発明は、新たなタイプの副室装置を作り出すという課題に基づいている。   There is a need for an auxiliary chamber device that is less susceptible to wear. Starting from here, the invention is based on the task of creating a new type of sub-chamber device.

この課題は、請求項１に記載の副室装置によって解決される。本発明によれば、本体セクションが、ノズルセクションに取り外し不可能に結合され、シリンダヘッドを越えて主室燃焼室内に突出し、このため、副室燃焼室及び主室燃焼室が、副室装置における主室燃焼室内に突出するセクションの領域において、一方では本体セクションによってかつ他方ではノズルセクションによって互いから分離されている。これにより、副室装置は、摩耗の影響を受けにくく提供される。   This problem is solved by the auxiliary chamber device according to claim 1. According to the invention, the body section is irremovably connected to the nozzle section and projects beyond the cylinder head into the main chamber combustion chamber, so that the secondary chamber combustion chamber and the main chamber combustion chamber are in the secondary chamber device. In the region of the sections projecting into the main chamber, they are separated from one another by the body section on the one hand and by the nozzle section on the other hand. Thereby, the sub-chamber apparatus is provided less susceptible to wear.

本発明の有利な第１のさらなる発展によれば、副室装置における主室燃焼室内に突出するセクションの、主室燃焼室に面する側では、ノズルオリフィスの領域での副室装置が、隣り合うノズルオリフィスの間ではノズルセクションによって、かつノズルオリフィスとシリンダヘッドとの間では本体セクションによって規定又は画定されている。これに起因して、副室装置における摩耗の影響の受けやすさは、副室装置における主室燃焼室内に突出するセクションの、主室燃焼室に面する側で、低減される。   According to an advantageous first further development of the invention, on the side of the section projecting into the main chamber of the auxiliary chamber arrangement on the side facing the main chamber, the auxiliary chamber arrangement in the region of the nozzle orifice is adjacent It is defined or defined by the nozzle section between the matching nozzle orifices and by the body section between the nozzle orifice and the cylinder head. Due to this, the susceptibility to wear in the auxiliary chamber device is reduced on the side of the section projecting into the main chamber combustion chamber in the auxiliary chamber device facing the main chamber.

本発明のさらなる発展によれば、副室装置は、副室装置における主室燃焼室内に突出するセクションの、副室燃焼室に面する側では、ノズルセクションのみによって規定又は画定されている。これに起因して、副室装置における摩耗の影響の受けやすさの低下は、副室燃焼室に面する側で、提供される。   According to a further development of the invention, the auxiliary chamber device is defined or defined only by the nozzle section on the side facing the auxiliary chamber combustion chamber of the section projecting into the main chamber combustion chamber in the auxiliary chamber device. Due to this, a reduction in the susceptibility to wear in the auxiliary chamber arrangement is provided on the side facing the auxiliary chamber combustion chamber.

本発明のさらなる発展によれば、副室装置は、副室装置における主室燃焼室内に突出するセクションの領域の、副室燃焼室に面する側では、一方では部分的に本体セクションによってかつ他方では部分的にノズルセクションによって規定又は画定されている。これらの特徴は、副室燃焼室に面する側において副室装置における摩耗の影響の受けやすさを低減するためにも働く。   According to a further development of the invention, the sub-chamber arrangement comprises, in the region of the section projecting into the main chamber of the sub-chamber arrangement, on the side facing the sub-chamber, one part partly by the main section and the other. Are partially defined or defined by the nozzle section. These features also serve to reduce the susceptibility to wear in the sub-chamber arrangement on the side facing the sub-chamber combustion chamber.
