A gas engine has a control system having a pilot control device for adjusting the operating state of the engine in response to changes in limiting conditions that are monitored. The control system further includes a knock monitoring device which is superordinate with respect to the pilot control device when the operating state reach a minimum distance from the knocking limit of the gas engine. The knock monitoring device prevents the engine from being damaged from circumstance which can not be protected against via the pilot control device.

Gas engine

A gas engine with electronically controlled and/or regulated injection of relatively small quantities of injection oil in such a way as to improve the metering accuracy of the injection oil quantity, the flexibility with which the required ignition oil quantity is provided and the ability to freely preset the timing of ignition oil injection. The engine comprises a separate electronically controllable injection system for each cylinder including at least one ignition oil injection device 13 connected via an injection line 14 to a separate ignition oil hydraulic pump 16 which is in fluid communication with a pressure accumulator 15. An electronically controllable switching device 19 associated with the injection device 13 is electronically connected to an engine control device 20 that controls, regulates and monitors the ignition oil injection.
