Engine Management
- Central control
- All functions of the gas engine management are taken over
- Among other things, speed and mixture control, ignition control, engine monitoring and other functionalities are integrated in the control unit
Air-Fuel Ratio Control
- Integrated mixture control
- Power, lambda or NOx as feedback signal
- Tailored system solutions for different gas qualities
Speed Control
- Integrated speed control
- Rapid response to changes in speed and load
- Combination with all HEINZMANN actuators possible
Gas Mixers
Gas mixers are indispensable components in the mixture control systems of gas engines. They guarantee the desired ratio of fuel gas and air regardless of the operating conditions.
- Suitable for naturally aspirated engines and turbocharged engines
- Constant mixture ratio
- Suitable for all gas types
- Uniform air-gas-mixture
- No maintenance required
- Low drop in pressure
Mechanical Gas Valves
LES-GTs are mechanical gas valves for air-fuel-ratio control (AFR) of gas engines. They are available with several cross sections and applied together with Venturi based gas mixers. Due to their design, these valves are totally maintenance-free and long lasting. Main applications are gas engines, working at one single operating point. Gas flow optimum is adjusted by positioning a specially shaped piston inside the LES-GT gas valves.
Electronically Controlled Gas Valves
The electronically controlled E-LES gas valves are a great solution for gas engines. Driven by a stepper motor, they are available both with (E-LES LC) and without (E-LES SMC) lambda control. They are located in the gas line downstream of the zero-pressure governor, and are connected to the inlet of the gas mixer. They can be used to set the required gas volume very precisely in every operating state and correct it as required.
Throttle Valves with Positioner
HEINZMANN throttle valves with integrated positioner are intended for small and medium-sized gas engines. The direct-acting integrated actuator operates in 4Q mode. It is supplied with the tried-and-tested contactless position feedback and an integrated return spring.
- Fast Response
- No maintenance required
- Compact
Throttle Valves
Throttle Valves
HEINZMANN throttle valves control the flow rate of the gas-air mixture. Thanks to the wealth of sizes from DK 50 to DK 400 and the dense design, these models can handle a wide range of power outputs and operating pressures. The control angle for the throttle valves is 75°. Both control directions can be used in equal measure.
- Suitable for naturally aspirated engines and turbocharged engines
- Suitable for all gas types
- Bearings ensure little torque is required
- Shaft and throttle valve made of stainless steel
- Standard flange sizes
- No maintenance required
