Abstract
The temperature of the working gas in the heating chamber of each of a number of cylinders is continuously measured. An electronic selection circuit selects the lowest measured temperature as a control parameter by which the speed of a blower in the common air supply is controlled for providing an air flow proportional to blower speed. A pressure-detecting device measures the air flow through a pressure converter provides an electrical signal that normally controls the valves of the respective fuel supplies for the combustion chambers of the cylinders, but a monitoring device for each cylinder compares the measured working gas temperature with a pre-set maximum value so that when the maximum value is exceeded, the fuel supply valve is changed over to control by the output of the monitoring device, to reduce the fuel supply until the maximum temperature is no longer exceeded in that cylinder. For still a higher temperature of the working gas in any cylinder, determined by another sensor, a general shutdown valve reduces the common fuel supply. An auxiliary air supply provides atomizing air for fuel injection.
