System of ignition for engine J20

The general description

For the vehicles equipped with additional system of restriction of movement "air bag" (a safety air cushion):

  • Service of components of an air cushion of safety ("air bag") and near to them or works with electroconducting should be carried out only by authorised dealer SUZUKI. Non-observance of safety measures can lead to inadvertent operation of system or put system out of action. Any of these two conditions can lead to a serious trauma.
  • Works on maintenance service should be begun not earlier than in 90 seconds after the ignition switch is translated in position LOCK/ЗАМОК and the negative cable is disconnected from the battery. Otherwise the system can be activated reserve energy of the module of sensor controls and diagnostics.

The given system of ignition is a system of direct ignition. It consists of parts as it is described more low and has system of the electronic control of ignition.

  • ECM (or PCM)

Defines an engine condition on signals from sensor controls, defines the most suitable time of an advancing of ignition and time when the electricity should be submitted on a primary winding, and sends a signal on an igniter (in the ignition coil).

  • Assemblage of the coil of ignition (including an igniter and the ignition coil)

The ignition coil has the built in igniter which includes and disconnects a primary current of the coil of ignition according to a signal with ECM (or PCM). When the primary current of the coil of ignition is disconnected, the high voltage is induced in secondary electroconducting. One coil of ignition is responsible for ignition only in one cylinder.

  • Spark plug and шумоподавитель
  • CMP-sensor control, TP-sensor control, ECT-sensor control and MAF-sensor control

This system of ignition has no distributor and high voltage wires, but each cylinder has the ignition coil, and the secondary pressure appearing in the coil of ignition, moves on a spark plug directly. Also a signal () go from a CMP-sensor control on ECM (or PCM). To operate each coil of ignition it is independent through an igniter (in assemblage of the coil of ignition).
