摘要： (57) Abstract The invention controls combustion of a cylinder/s and has a controller (15) to control ignition timing and monitoring means (16) to monitor a flywheel (4) and ignition maps (13). The controller (15) is also arranged to monitor main gas valve duration, and has pressure monitoring means (11) to monitor pressure in at least one cylinder (2). The controller (17) of the invention is arranged to form an average heat release timing and compares the average heat release timing with nominal heat release timing, determines whether the average heat release timing is before or after the nominal timing, and determines whether the main gas valve duration has changed. In addition the second controller (17) adjusts the ignition timing in cooperation with the controller (15) if the main gas valve duration has remained unchanged, and the average heat release timing is before or after the nominal heat release timing.

摘要： Invention relates to method of operating an electric power generator set (1) comprising a gas operated internal combustion piston engine (10) coupled with an electric generator (12) in which gaseous fuel is fed as a main fuel into combustion chambers of the engine along with the combustion air and the mixture of the gaseous fuel and air is ignited by injecting an amount of pilot fuel (28), the timing and duration of the pilot fuel injection is controlled based on engine's operational parameters and the state of the electric grid (16), to which the generator is connected, is monitored. In the method in case of a disturbance in the grid is detected, the control of the timing and/or duration of the pilot fuel injection is effected based on the grid disturbance.
