VEZ ignition system

The fully electronic ignition system type VEZ is a transistorized equipment with an electronic control system. This system is designed to control ignition timing based on an appropriately designed characteristic. For normal ignition purposes, this is realized by two centrifugal and reduced pressure regulators. In an electronic ignition system, the optimum ignition point is determined by several parameters of engine operation.

This is the engine speed, engine temperature and engine load at the moment, the gear in the gearbox. The ignition timing has been chosen to achieve the best mixture conditions. Modern engines operate at as high a compression ratio as possible, since then the use of fuel is more advantageous. However, at a high compression ratio, uncontrolled explosive combustion can occur.

Continuously occurring explosive combustion can damage the engine. To prevent this, it is necessary to use an explosive combustion sensor, which detects abnormal combustion and delays ignition. This sensor is mounted on the engine block and wired to a VEZ or Digitant ignition system.

In the event that any control parameter is missing, malfunctions may occur in determining the characteristics of the ignition timing. This can cause, for example, a reduction in engine power and/or an increase in fuel consumption.
