Micro mass flow controller for a mini-HCCI-motor driven power generator

Schiffer, M. LU ; Stefanini, C. ; Tunestål, P. LU orcid and Obermeier, E. (2007) 4th International Conference on Solid-State Sensors, Actuators and Microsystems, TRANSDUCERS and EUROSENSORS '07 p.1127-1130
Abstract

A piezoelectric micro mass flow controller (MMFC) for liquid fuel injection into a mini-HCCI-motor for power generation is introduced. Piezoelectric actuation ensures negligible power consumption for fuel injection allowing self-sustaining operation. A pressurized fuel tank is connected to the MMFC which is designed like a normally-closed, on-/off-operating valve. Integrated piezoresistors are used for feedback control and an implemented pn-diode (sensitivity: -2.5 mV/K) enables on-chip temperature monitoring. Flow rates of up to 70 μl/s at 100 kPa fuel pressure have been demonstrated. The power consumption of the piezoelectric actuator during steady state operation is max. 20 μW at 120 V.
