Embodiment Construction

[0051] figure 1 Shown is a schematic view of an internal combustion engine 1 with a pre-chamber 2 and a main combustion chamber 3 assigned to the pre-chamber 2 . The purge gas S is fed to the prechamber 2 . This purge gas S consists of synthesis gas R and propellant B 2 . Synthetic gas R and propellant B 2 The mixture is mixed in the purging gas mixer 9 and the resulting gas mixture is supplied as purging gas S to a pre-chamber 2 or pre-chambers 2 of the internal combustion engine 1 .

[0052] Here, synthesis gas R is produced in fuel converter 4 . multiple streams B 1 , D, L, A are fed to the fuel converter 4 for a conversion process known per se, in which hydrocarbon-containing fuel B 1 The reaction produces H 2 and CO synthesis gas R. These streams B are carried out in this example by means of the stream mixer 7 1 , D, L, A delivery, the stream mixer will be delivered to its stream B 1 , D, L, A are mixed into a stream gas mixture and sent to the fuel converter 4....

Abstract

The invention relates to a method for operating at least one precombustion chamber-fired internal combustion engine (1), in particular a stationary gas Otto cycle engine, having a pilot chamber (2) and a main combustion chamber (3) associated with the precombustion chamber (2), wherein a gas mixture is fed to the precombustion chamber (2) as flushing gas (S), wherein a synthesis gas (R) generated in a fuel reformer (4) and a fuel (B2) from a fuel source are fed to the flushing gas (S) and wherein a fuel (B1) and at least one further substance stream (D, L, A) are fed to the fuel reformer (4) for the reforming process, wherein at least one operating parameter of the at least one internal combustion engine is monitored, wherein in accordance with a change in the at least one operating parameter the chemical composition of the flushing gas (S); is modified by changing the mass stream of the at least one further substance stream (D, L, A).

Description

technical field [0001] The invention relates to a method for operating at least one internal combustion engine with pre-chamber ignition, in particular a stationary gas-Otto engine (Gas-Otto-Motor), comprising a pre-chamber and an associated pre-chamber the main combustion chamber of the , wherein a gas mixture is fed to the pre-chamber as purge gas, wherein synthesis gas generated in the fuel converter and propellant from a propellant source are fed to the purge gas , and delivering a fuel and at least one other stream to a fuel converter for the conversion process. Background technique [0002] In an internal combustion engine operated with an Otto engine, the propellant-air mixture in the combustion chamber is ignited by means of an ignition device, wherein the gas mixture introduced is usually ignited by a spark strike at an electrode of a spark plug. As an alternative, it is also known to use laser spark plugs as ignition means, in which laser spark plugs the necessary...
