Embodiment Construction

[0013] figure 1 A schematic partial view of an internal combustion engine according to the invention is shown, which is preferably designed as an Otto gas engine, namely in the region of a cylinder head 1 of the internal combustion engine, which delimits a main combustion chamber 2 of the internal combustion engine . according to figure 1 , an attachment 3 is provided on the cylinder head 1 of the internal combustion engine, which is preferably screwed into the cylinder head 1, wherein the attachment 3 defines a pre-chamber 4, which is separated from the main combustion chamber 2 and is separated by at least one Opening 5 is connected with the main combustion chamber.

[0014] Projecting into the pre-chamber 4 is at least one ignition device 6 which is preferably shielded. Gas can be sprayed into the pre-chamber 4 under high pressure by the gas nozzle 7 that is connected on the high-pressure gas pipeline, wherein the gas injected into the pre-chamber 4 under high pressure b...

Abstract

The engine has a pre-chamber (4) connected with a main combustion chamber (2) through an opening (5). A combustion gas nozzle (7) is attached to a high pressure combustion gas line and is led into the pre-chamber for mixing combustion gas with a lean gaseous fuel-air mixture provided in the pre-chamber. An ignition device (6) ignites enriched gaseous fuel-air mixture. The opening extends in a tangential direction of the pre-chamber so that the lean gaseous fuel-air mixture flowing into the pre-chamber from the chamber (2) is subjected to rotational flow in the pre-chamber (4).

Description

technical field [0001] The invention relates to an internal combustion engine. Background technique [0002] An internal combustion engine for gaseous fuels is known from DE 10 217 996 A1, which has a main combustion chamber and a pre-chamber separate from the main combustion chamber. The pre-chamber is connected to the main combustion chamber via at least one opening. A gas nozzle connected to the pressurized gas pipeline is introduced into the pre-chamber for spraying gas under high pressure into the pre-chamber. In this case, the gas mixes with the lean gas-air mixture in the pre-chamber to enrich the mixture. An ignition device protrudes into the pre-chamber for igniting the enriched gas-air mixture and thus ultimately for igniting the gas-air mixture in the main combustion chamber. [0003] At high pre-chamber pressures, in the case of spark ignition, a high electrical power must be obtained in order to ignite the gas-air mixture in the pre-chamber, which represents ...
