Engine Management Principle.
The trainer should be neatly laid out to represent the typical automobile engine with sensors actuators, fuel system, ignition system, emission system and engine control unit. The unit should contains a circuit board with electronics components and micro-controller systems, system diagrams, power supply, electrical test leads, and student experiment manual presented in hard copy and pdf format.
The experiment exercise starts with relevant theory of engine management systems and proceed to practical activities using the circuit board, multimeter and oscilloscope for observation, measurement and troubleshooting. Multimeter and oscilloscope is as an optional item. Manual provided, must clearly show the following educational Objectives are met.
Educational Objectives:
Using schematic and block diagrams in automotive electronics.
Identify a typical ECU Voltage reference values.
Study the functions of both crankshaft and camshaft position sensors.
Identify correct operation of the engine coolant temperature sensor.
Determine the typical voltages produced by an exhaust gas oxygen sensor.
Diagnose faults with the throttle position sensor potentiometer.
Identify the advantages of computer controlled vehicle systems.
Convert flash type trouble codes into OBDII codes.
Observe the influence of engine temperature to injection time.
Recognize that air to fuel (A/F) ratio is affected by injector open time.
Troubleshooting fuel injectors circuit.
Recognize the operating principle of air injection (turbo system).
Measure resistance of the EGR solenoid.
Activate computer self-diagnosis for troubleshooting purposes.
Circuit board features :
Exhaust gas analyzer and OBDII diagnostic with LCD display, knock sensor, intake air temperature sensor, throttle position sensor, coolant temperature sensor, O2 sensor, MAP sensor, canister purge solenoid, ignition coils, spark plug indicators, fuel injectors indicators, camshaft sensor, crankshaft sensor, idle air valve, EGR solenoid, Engine Control Unit, Ignition switch, engine speed indicator.
Accessories:
Experiment manual.
Power cord.
Include Additional Items:
