KRONOS provides a choice of four different AFR systems for mixture control - depending on the required control properties, gas types and engine sizes. As a customer, you can be sure of finding the right solution for your requirements regardless of engine size, specific application or requirements for operation and exhaust emissions.
KRONOS 40 is a speed/load control system for gas engines with solenoid-controlled gas admission valves. The system supports single cylinder outputs from 100 kW to 1 MW with up to 20 cylinders. The gas injection valves inject the gas in front of the inlet valve of the combustion chamber, the gas quantity to the individual cylinders is individually adjusted by a control unit.
KRONOS 30 is an electronically controlled AFR control system for setting speed- and load-dependent lambda values in order to achieve ideal engine behaviour under all operating conditions. The flexible concept can be used to control engines with large fluctuations in the gas, engine and ambient parameters. The main areas of application are biogas and lean-burn engines that are supplied with slightly increased gas pressure via blowers.
KRONOS 20 is an electronically controlled AFR control system for setting speed- and load-dependent lambda values in order to achieve ideal engine behaviour under all operating conditions. The main areas of application are natural gas and biogas engines that are supplied via a zero pressure regulator.
KRONOS 10 is a simple mechanical system for adjusting the air-fuel ratio, consisting of a gas-air mixer and a mechanical gas adjustment valve. This simple solution can be used for engine sizes between 25 kW and 3 MW where precise emission control is not required.
