EB-560 Single Point Fuel Injection

Electronic fuel injection and electronic ignition have improved engine performance and efficiency as well as reduced air pollution in many modern automobiles. The EB-560 training system uses a unique combination of qualitative simulations and quantitative experiments to familiarize the student with the basic principles of operation and troubleshooting of single point fuel injection (SPFI) as implemented in many medium performance engines. The EB-560 training system simulates the ECM monitoring of the 02 sensor, engine air temperature, engine coolant temperature, throttle position, and manifold absolute pressure sensors. The fuel metering is simulated in a multicolor LED schematic that stows the change in fuel flow under various conditions. The operation of the fuel pump and ignition timing are also simulated. Real faults can be inserted by connecting a cable from the EB-560 panel to the PU-2000 or PUZ-2000 mainframe. Interactive courseware accompanies each experiment and trouble shooting exercise. In order to provide the student with a general understanding of various types of electronic fuel injection, the BOSCH Monojetronic and the GM TBI and Multec electronic fuel injection systems are studied.
