How does electronic ignition work

Modern day electronic ignition no longer requires as many electro-mechanical parts in the system, the key one being the distributor. It is built upon a solid state circuit of sensors that trigger a switch, which passes current through the ignition coil. Watch the animated video showing the working of electronic ignition system.

Compared to traditional ignition systems, an electronic ignition system does not need a resistor to reduce the operating voltage of the primary circuit to prolong the life of points. This means that the ignition system is operating on full battery voltage, and thus a stronger spark is possible.

This still uses the points but not to collapse the feild but as a mere switch. It can be modified to work on volts. Not successful on all cars and 25BHP may well be produced by some - ads usually say Up to 25bhp. Not usually expensive but do yu not think this mod would be on all cars already if it was any. Know the basic working of an automobile ignition system working on battery.

Replacement coils should be not less than Ohm primary resistance. The ignition system consists of an ignition coil, distributor, distributor cap, rotor, plug wires and spark plugs. How Ignition Systems Work Before you can figure out how to make something work better you first need to understand how it works.

An ignition system builds up a charge then releases it at the right moment to ignite the air fuel mixture in the cylinder. An ignition module is the component in electronic ignition systems that functions as the contact breaker for the coil or coils. In most basic terms, an ignition module is an electronic replacement for ol mechanical contact breakers like ignition points. The widest application for spark ignition internal combustion engines is in petrol (gasoline) road vehicles: cars and motorcycles. Dwell is the time that the points or the electronic module in an ignition system are close and the coil is charging.

Standard ignition systems have a fixed dwell angle, meaning that the coil is. For many years, the contact point ignition was the favored system to control the timing of the ignition spark. However, as electronics in general became more reliable and less costly to produce, manufacturers turned to full electronic systems—cutting out the mechanical contact points. Power pulses to charge the ignition coil are controlled by electronic means and does a. Last week, we looked at variable valve timing.

It does not require a battery to work. This has advantage and disadvantages. No battery means less weight, less wiring creating more reliability. Electro-Magnetic Induction.

The downside is it takes greater mechanical force to turn a magneto than a distributor meaning more strain on the components driving the magneto and a reduction in mileage. How electronic ignition works Many newer cars have an electronic ignition system which times the spark more precisely than a mechanical system. It also wears less, so that it is always at peak efficiency, and it overcomes one problem of a mechanical systeat high engine speeds a mechanical system does not work at peak efficiency.

Some coils have an internal resistor, while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the car. The change is very slight in most cases, but it is enough to drive small speakers. For example, if you have a digital watch with a beeping alarm, the beeper is a little piezoelectric speaker. In an electronic system, you still have a distributor, but the points have been replaced with a pickup coil, and there’s an electronic ignition control module. A capacitor discharge ignition or CDI works by passing an electrical current over a circuit capacitor.

These are far less likely to breakdown. This type of ignition builds up charge quickly. There are two types of electronic ignition systems used in a gas grill. One is known as a piezo starter or a piezo ignition.

The electronic ignition system in a gas furnace is a modern development that provides more reliable performance than a standing pilot and offers energy savings. A Capacitor Discharge Ignition is an electronic ignition device that stores an electrical charge and then discharges it through an ignition coil in order to produce a powerful spark from the spark plugs in a petrol engine. Here the ignition is provided by the capacitor charge.

The capacitor simply charges and discharges within a fraction of time making it possible to create sparks CDIs are.
