Stand-Alone Direct Injector Driver Systems (SADI) Stand-Alone Kits
Chalmers University: Combustion Engine Laboratory For the experimental work on a 5 cylinder light duty diesel engine we use an open control platform based on hardware and software from National Instruments and Drivven. This control system is implemented in LabVIEW and uses a mix of a field programmable gate array (FPGA), a PowerPC processor, and a desktop computer to perform data acquisition and control tasks. The control platform will enable easy implementation and validation of developed control and sensing algorithms. Tomas McKelvey, Chalmers University of Technology (Sweden) www.ni.com/enginecontrol
