Conventional Ignition System Model
(AT - 077)
  • Observation of the internal structure of the ignition system of petrol engine.
  • Understanding the operation principle of the ignition system of petrol engine.
  • Visualization of Spark & Firing order.
  • Conventional ignition system trainer (AT - 077)
  • Hard copy user manual

The conventional ignition system is designed to illustrate the structure and operating process of the ignition system based on real components. Such systems include various components that work together in harmony and precision to achieve the function of the system. Trainees can understand the function of each component and how the ignition switch activates the voltage from the battery to the ignition coil to produce the engine spark.

                                     
  • The training system applies theoretical teaching and maintenance training of the ignition system.
  • The components used are from actual automobile petrol engines. In order to show the spark generation & firing order.
  • The system contains conventional distributor, spark plugs, manual crank, electric motor, speed control, and battery 12V.
  • Distributor can be driven by a low-speed electric motor.
  • A small electric motor is provided to give the rotational motion that would have come from the engine to the distributor to chop the electrical signal from the battery according to firing order.
  • The rotational motion of the distributor causes spark on 4 spark plugs.
  • Each spark plug fits into the cylinder head of the internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark. Spark plugs have an insulated center electrode connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder.
  • A transparent protective cover is used to surround the spark plug which allows the sparks process to be observed safely.
  • The unit also includes a resistor and coil for magnifying the battery voltage that has been chopped by the distributor up to a sufficient level necessary for sparks to be produced.
