The ignition switch consists of a small power supply and two wires. Despite such a simple device, this rather complex technical unit increases the engine output even at low speeds with a poor-quality mixture.

The operation of the ignition switch

It is used to drive low-quality gasoline with a low octane number. It is designed to give the motor a high kickback. The switch helps create a more productive spark so that the fuel / air mixture ignites better.

It will also be useful for cars on which gas equipment is installed. The switch tests all ignition components, adjusts the POP when switching to methane.

Most often, such elements are combined with an electronic control unit.

A switch is a combination of several components, such as:

1. Candles.
2. Transistors.
3. Sensors.

Used in various HELLA brand Switch Unit, ignition system. The switch has several obvious advantages:

1. Prevents interruptions at high speeds.
2. Increases the reliability of the power supply.
3. The volume of the cylinders of the power unit increases.
4. The spark is stronger.
5. Prevents loss of distributor power.
6. Provides good idle speed.
7. Reduces fuel consumption.
8. A cold engine is much easier to start.
