Abstract
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.
Claims10
A combination including an engine and a control system for controlling said engine in response to changing limiting conditions, said control system comprising:
- a pilot control device having sensors for measuring the limiting conditions;
- activators for calculating output signals in response to the limiting conditions;
- a final control device connected to said engine for adjusting an operating point of said engine in response to said output signals, said pilot control device operatively connected such that said engine operating point is not moved closer to the limits of the operating range than a minimum distance;
- and
- a knock monitoring device operatively connected to said engine for one of adjusting an output of said engine and stopping said engine when said operating point reaches the minimum distance to the limits of the operating range.
