Interactive Computerized Automotive system.

The whole system has to be modularized to provide electronic and automotive courses with step-by-step experiments on technological educational training.

All theoretical, experimental and practical leaning procedures are supported by a personal computer assisted supervision and dedicated software.
The system has to simulate the operation of fuel injection system, ignition system, and the control of exhaust gas, etc. Experiments include the sensors characteristic and operation of various sensors and actuators monitored by microprocessor on the main unit.

Features
•    The program should enable computer interface monitor control
•    Data of fuel injection, ignition and exhaust gas should be acquired and monitored by computer.
•    Able to trouble-shooting simulation function
•    Switch-off input output function when trouble-shooting is made
