Method for operating at least one precombustion chamber-fired internal combustion engine

摘要

The invention relates to a method for operating at least one precombustion chamber-fired internal combustion engine, in particular a stationary gas Otto cycle engine, having a pilot chamber and a main combustion chamber associated with the precombustion chamber, wherein a gas mixture is fed to the precombustion chamber as flushing gas, wherein a synthesis gas generated in a fuel reformer and a fuel from a fuel source are fed to the flushing gas and wherein a fuel and at least one further substance stream are fed to the fuel reformer 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 is modified by changing the mass stream of the at least one further substance stream.

1. A method of operating at least one prechamber-ignition internal combustion engine comprising a prechamber and a main combustion chamber associated with the prechamber, the method comprising:
feeding a combustion fuel and at least one further substance flow to a fuel reformer for a reforming process; mixing a synthesis gas produced in the fuel reformer and an engine fuel from an engine fuel source to produce a scavenging gas, mixture; feeding the scavenging gas to the prechamber; monitoring at least one operating parameter of the at least one internal combustion engine; and modifying a chemical composition of the scavenging gas by changing a mass flow of the at least one further substance flow in dependence on a change in the at least one operating parameter.
