Control    

The control of the Chiron is realised by means of sensors, actuators and electronics. Synchronisation of piston movement and fuel injection can only be realised by electronic control. Two simple and robust inductive sensors are used to determine the position of the plunger. The control hardware is built around an off the shelf SIEMENS 40 Mhz 16 bit processor.
The compression ratio is controlled by changing the pressure level in the compression accumulator; the BDC-position of the piston is kept as constant as possible. A pilot operated digital valve is used to start each pump cycle. This valve initiates the power control which is called Pulse Pause Modulation.
