System Integration The goal of the MEMS Rotary Engine Power System (MEMS REPS) is to develop an autonomous, commercially viable, portable power system based on an integrated power generator and rotary internal combustion engine. This system is designed to leverage the specific energy of liquid hydrocarbon fuels and deliver a continuous power output of 100 m. W. © 2005 University of California Prepublication Data Spring 2005
Fuel Management Fuel/air intake integration design in LTCC. The pressure response for flow of water in a 133 um microchannel, at 100 degrees Celsius. A discrete Fourier transform is performed on the data and the amplitude of the results plotted on the right. © 2005 University of California Prepublication Data Spring 2005
