The charging resistance is also so designed that it controls the required current in the SCR. This high voltage is used to charge the tank capacitor (or condenser) to this voltage through the charging resistance. power circuit through the ignition switch, which is designed to give or increase the voltage to 250-350 volts. If you need to change it you will learn exactly how in this video. A 6-12 volt battery is connected to DC to DC converter i.e. An integrated Piezo igniter is a feature of our Lite Stoves. It mainly consists of 6-12 V battery, ignition switch, DC to DC convertor, charging resistance, tank capacitor, Silicon Controlled Rectifier (SCR), SCR-triggering device, step up transformer, spark plugs. (a) Capacitance Discharge Ignition system

This changes the point gap, which changes ignition timing and reduces spark energy, thus necessitating their servicing and resetting at smaller periods.Įlectronic Ignition System is as follow :.

They burn and wear during normal operation.

For realizing a short-lasting high voltage it has been proposed to use a piezo-electric ignition device of the type which is used in cigar lighters. By the early 1970s, most automotive engines using a contact-point distributor could not meet exhaust-emission standards. A piezoelectric ignition device comprising, a cylindrical housing, an electrically insulated piezoelectric element having electrodes and being disposed within said housing.No electrons are gained or lost, they are just pushed around. Piezoelectric materials exhibit both a direct and a reverse piezoelectric effect. Pressing the button causes a spring-loaded hammer to hit the piezoelectric crystal, producing a sufficiently high voltage electric current that flows across a small spark gap, thus heating and igniting the gas. Piezoelectricity, also referred to as piezo, is the ability to change electricity into power.

Although the conventional mechanical contact breaker point type electrical ignition system has been very common in use because of its simplicity, yet due to its drawbacks and limitations the same is being fast replaced by the electronic ignition system. Applications: Piezoelectric ignition units designed to light gas burners and piezoelectric element.
