IC engine with externally-supplied ignition
The IC engine has the ignition of a compressed fuel mixture taking place by a laser beam (16) focused at an ignition point (17) and introduced into the combustion chamber (7) via an optic fiber (9). The optic fiber lies in a sealing element (6) bounding the combustion chamber which is located in a s...

| description | The IC engine has the ignition of a compressed fuel mixture taking place by a laser beam (16) focused at an ignition point (17) and introduced into the combustion chamber (7) via an optic fiber (9). The optic fiber lies in a sealing element (6) bounding the combustion chamber which is located in a sectional plane through the combustion chamber. The sealing element is preferably formed by a cylinder head gasket (5). The optic fiber opens out in the sectional plane almost radially into the combustion chamber. The focusing of the laser beam takes place by a locally melted-on optic fiber end (25) in the region of the opening into the combustion chamber.
Um bei einer Brennkraftmaschine mit Fremdzündung, bei der die Zündung eines verdichteten Kraftstoffgemisches zumindest teilweise durch zumindest einen über mindestens einen Lichtleiter (9) in einen Brennraum (7) eingebrachten, auf einen Zündort (17) fokussierten Laserstrahl (16) erfolgt, den konstruktiven Aufwand und Platzbedarf zu verringern, ist vorgesehen, daß der Lichtleiter (9) in einem den Brennraum (7) begrenzenden Dichtelement (6) liegt, welches in einer den Brennraum (7) durchsetzenden Schnittebene (6a) angeordnet ist, wobei vorzugsweise das Dichtelement (6) durch eine Zylinderkopfdichtung (5) gebildet ist. |
