The KRONOS 40 is a speed/power control system for gas engines with magnetically controlled gas injection valves. The system supports individual cylinders from 100 kW to 1 MW with up to 20 cylinders. The gas injection valves jet the gas upstream of the combustion chamber intake valve, and a control unit individually adjusts the gas quantity to the individual cylinders. To do this, it records the exhaust gas temperature, enabling precise cylinder-specific gas dosing. With additional HEINZMANN components, the system can be expanded to create a complete engine management system.
