Automotive Electronic Technology

Technosys  proposal consists of the following:

• A set of modules for the study of basic electricity and main electric circuits
• A set of simulation panels for electric and electronic systems in modern automobiles, complete with dedicated software for demonstration of the relevant theory and introduction of simulated faults.
• A set of panels with real components for demonstration
• A set of sectioned components
  Autotronics-Simulation panels
  AIR CONDITIONING FOR AUTOMOBILESThe simulator analyzes all me phases of the refrigeration cycle. In particular:
  - Relations between temperature and pressure in the refrigerant
  - Operation of the compressor
  - Operation of the condenser
  - Pressure switches
  - Temperature regulation
  ENGINE STARTING

  This simulation panel deals with the study of the starting techniques used in the Otto cycle motors. The main types of starting are here analyzed:

  
  Conventional with coil, with transistors and electronic starting.

  ELECTRIC CIRCUITS

  The following sections of tne efectric plant of the car are reproduced on the panel:

  
  -  Electrical supply
  - Starting
  -  Ignition
  - Fuel injection
  - Various end users (radío, defrosting, etc.)
  -  Indicators
  - Cooling and aeration
  - Windshield wipers
  - Signalling system
  - Lighting sysíem
  -  Mead lights
  - Antí-fog lights

  ENGINE SENSORS AND CONTROLSThe extensive use of sensors and actuafors comes from the need of the electroníc control panels to know in real time the actual values of the physical parameters to be controlled or which influence the behaviour of the car.ENGINE OPERATION

  The simulator takes into consideration all these aspects by performing the following functions:

  
  - Ignition phase
  - Heating phase
  - Lambda regulation
  - Quick acceleration/deceleration phases
  - Cut-off phase
  - Regulation of the injection time
  - Regulation of the advance angle
  - Regulation of the minimum rpm
  - Regulation of the knock
  - Limitation of the rpm 

  DIESEL ENGINE MANAGEMENT SYSTEMThis panel trainer provides realistic fault finding facilities using heavy vehicle schematic diagrams. An easily understood schematic system represents the starting and fuel injection systems of a typical heavy vehicle. The student is able to see the exact operation of the various circuits as used in trucks and buses and is able to gain a hands-on introduction to each of the components and devices found in typical heavy vehicle systems. All practical activities are carried out using the electrical/electronic circuits and devices mounted on the panel trainer.

   

   

This trainer has been designed for the study of the whole electric circuits in modern motor vehicles relevant to internal and external signals and lights.
the trainer is suitable for:

• the demonstration of signals and lights working in normal conditions

• the training to the diagnosis, with the introduction by the teacher of a set of faults that must be diagnosed by using the standard workshop instrumentation applied to the different test points of the trainer.
The trainer includes the following components:
o starting block with key
o dashboard and other internal signals
o external signal group
o external light group
o internal light group
o fuses group
o doors lockup signal
o brakes signal
o measurement terminals
o battery 12vdc
o battery charger feeder
The system is supplied with a technical manual including:
? ? ? Description of the system and of its main components
? ? ? Installation, use and maintenance
? ? ? Guided experiments
? ? ? Reproducible modules for the obtained data
? ? ? Tables and graphs about endothermics, electronics and autotronics
The main guided experiments are:
? ? ? Identification of components and their function
? ? ? System operation in normal conditions
? ? ? System operation in presence of faults
? ? ? Control measurements
? ? ? Faults diagnosis procedure
? ? ? Correct procedure for the removal of the faults
n. B: all the components of the trainer are of industrial type; the technical characteristics and the performances are related to what available in the market when ordering.
