Optimal control technology for any type of gas engine

The newly developed and extensively tested XIOSGas for gas engines combines all the advantages of HEINZMANN control systems: Speed control, mixture control, ignition control and knock control, as well as extensive engine management functions, can be found in a central control unit. This can be combined with a wide selection of hard components and is therefore suitable for any type of application.

System Features

Central control of all gas engine system functions by the modular and multifunctional controller XIOSGas.

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.

Throttle Valves with Actuators

HEINZMANN throttle valves with actuators are the ideal components for ensuring optimal engine control, including for turbocharged engines. As throttle valves, they regulate the engine speed by metering the mixture accordingly, and boast an unusually long service life. What’s more, they can be used in special applications as a gas valve in order to control the air-fuel ratio. Alternatively, they can also be used as a turbo bypass valve.

  • Constant mixture ratio
  • Suitable for all gas types
  • Uniform air-gas-mixture

  • Low drop in pressure

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.

Electronically AFR Control Uebersicht2

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.

Ignition Control Unit

The flexible PHLOX II control unit with capacitive ignition and high ignition energy lies at the heart of the HEINZMANN ignition systems. Available in three versions, the control unit is suitable for engines with a maximum of 8, 12 or 16 cylinders. Two control units can be used to actuate engines with up to 24 cylinders. PHLOX ensures precise ignition timing and that the mixture ignites well. The variable ignition energy and the self-diagnosis function reduce the wear on the spark plugs, thereby increasing their service life.

Technical data

  • Number of cylinders: up to 8 (IC-08), up to 12 (IC-12, IC-12A, IC-12B), up to 16 (IC-16, IC-16A, IC-16B)
  • Speed: 30 ... 3000 rpm
  • Spark duration: 300 ... 600 µs
  • Spark energy: 25 ... 280 mJ (32 levels)

Coils & Rails

High-performance ignition coils with optimised output power and a separate earth connection are the perfect accessories to complement the HEINZMANN PHLOX II ignition control unit. They enable high output voltages when the engine is run continuously and are suitable for temperatures up to 125°C.
On the pre-assembled ignition rails, the coils are mounted directly on the rail. The cables are protected inside the rail profile, ensuring a long service life and reliable operation.

Ignition leads

Spark plug connectors made of high-quality Teflon are resistant to high temperatures and voltages, and offer ideal insulation against sparks.

Spark plugs

The special industrial spark plugs for stationary gas engines feature iridium-reinforced electrodes to ensure a long service life and reliable operation.

Speed sensors

Both inductive sensors and Hall sensors are available with different lengths and thread sizes. Thanks to their robust design, inductive sensors are ideal for use in harsh ambient conditions.
Compared to inductive sensors, the advantage of Hall sensors is that the output signal is independent of the speed and the distance from the sensor.

Trigger discs

Trigger discs are available in various designs to cover all possible applications.
