Leanmix Emission Regulation
For flexible and reliable compound regulation when using biogas.
The VariFuel2 is a high-tech variable Venturi type mixer that can constantly adjust to any fuel changes and allows the engine to operate at its most efficient point. Series 100, 140, 200 and 250 are available for engines with an air requirement up to 5.200 m3/h. Coupled to an air/fuel ratio controller, lean-burn or stoichiometric, it precisely regulates the mixture. It is very popular for applications with constant changes in calorific value of fuel.
The stepper motor driver developed by MOTORTECH guarantees the ideal control of the various types of MOTORTECH VariFuel2 air/gas mixers and throttle bodies with integrated stepper motor.
The air/fuel ratio mixer is a simple and cost-effective Venturi gas mixing system. The mixer is very well suited for naturally aspirated and turbocharged engines if the calorific value of the gas is stable and does not vary.
