Developing new combustion processes and injection components demands flexible control units that can be configured in a variety of different ways. FI2RE – Flexible Injection and Ignition for Rapid Engineering – is precisely this.

Our development control unit allows the user to operate all of the engine’s crank-angle-synchronous components without a production control unit.

FI2RE can be used on the engine and component test bench in many different ways.
For example, it is very easy to realize the injection spray process in which gas is blown into the intake manifold and taken to controlled combustion by directly injecting diesel. Even with its standard functionality, FI2RE is capable of actuating rail pressure pumps, camshaft actuators and throttle valves. The flexible angle system can be used for different sensors and signal shapes.

Depending on the task in hand, the basic FI2RE unit is easy to extend – with the TRA card, for example, that records thermodynamic data and processes them in real time. Our piezo power stage permits the flexible actuation of piezo injectors and provides new degrees of freedom in developing injection strategies, such as rate shaping. Further plug-in cards are also available for various applications. If clients are unable to find the right one for their particular need, we can also extend FI2RE to suit requirements.
