Abstract
Programmable open and closed loop electronics for control of an internal combustion engine. The following functions are integrated in a known method and the corresponding device: 'closed loop combustion control of a gas engine, program for automatic starting and stopping of the unit, monitoring of the temperatures and pressures of gas, water, lubricant and exhaust gas and of levels inside the installation, driving of the ignition unit, setting of the speed controller, control of the auxiliary circulation systems, monitoring of the generator winding temperature, self-monitoring of the control unit and of the probes, and storage of the measured values for monitoring and diagnostic purposes.' According to the invention, the concentration of nitrogen oxides (NO.sub.x) and/or of fluorine and/or of chlorine in the exhaust gas of the internal combustion engine is quantitatively measured with an exhaust gas sensor (6) continuously while the internal combustion engine is operating. The values of the nitrogen oxide emission are especially suitable both for monitoring and also for open and closed loop control of an appropriately equipped internal combustion engine.
