Abstract

A prechamber system for an internal combustion engine has a prechamber, a fuel introduction device, a dead space which connects the fuel introduction device to the prechamber. A channel is provided which connects the prechamber to the dead space.

First claim

The invention claimed is:

1. A prechamber system for an internal combustion engine, comprising:
a prechamber;
a fuel introduction device;
a dead space connecting said fuel introduction device with said prechamber; and
a channel directly connecting said prechamber with said dead space.

2. The prechamber system of claim 1 , further comprising a fixing segment formed as a thread to fix a spark plug to said prechamber, said channel being configured to open into said prechamber in a region of said fixing segment.

3. The prechamber system of claim 1 , wherein said prechamber has an overflow channel, said channel being configured to directly connect said overflow channel of said prechamber to said dead space.

4. An internal combustion engine comprising:
a main combustion chamber; and
a prechamber system including:
a prechamber;
a fuel introduction device;
a dead space connecting said fuel introduction device with said prechamber; and
a channel directly connecting said prechamber with said dead space.

5. The internal combustion engine of claim 4 , wherein said prechamber system further includes a fixing segment formed as a thread to fix a spark plug to said prechamber, said channel being configured to open into said prechamber in a region of said fixing segment.

6. The internal combustion engine of claim 4 , wherein said prechamber has an overflow channel, said channel being configured to directly connect said overflow channel of said prechamber to said dead space.
