What is ignition system PPT?

What is ignition system PPT?

 The system in an internal-combustion engine that produces the spark to ignite the mixture of fuel and air: includes the battery, ignition coil, distributor, spark plugs, and associated switches and wiring. …

How does a spark ignition work?

The simplest form of spark ignition is that using a magneto. The engine spins a magnet inside a coil, or, in the earlier designs, a coil inside a fixed magnet, and also operates a contact breaker, interrupting the current and causing the voltage to be increased sufficiently to jump a small gap.

What are the two types of spark ignition?

The working cycle of both spark-ignition and compression-ignition engines may be either two-stroke or four-stroke.

What is meant by spark ignition?

The term spark ignition is used to describe the system with which the air-fuel mixture inside the combustion chamber of an internal combustion engine is ignited by a spark. The resulting controlled explosion delivers the power to turn the reciprocating mass inside the engine.

What are the types of ignition?

Currently, we recognize four types of ignition systems used in most cars and trucks: conventional breaker-point ignitions, high energy (electronic) ignitions, distributor-less (waste spark) ignition and coil-on-plug ignitions.

What is ignition system and its main function?

ignition system, in a gasoline engine, means employed for producing an electric spark to ignite the fuel–air mixture; the burning of this mixture in the cylinders produces the motive force. The distributor routes the successive bursts of high-voltage current to each spark plug in the firing order.

What generates a spark for ignition?

When the high voltage produced by the ignition system is applied between the center electrode and ground electrode of the spark plug, the insulation between the electrodes breaks down, current flows in the discharge phenomenon, and an electrical spark is generated.

How does the ignition system operate?

When the ignition key is turned on, a low voltage current from the battery flows through the primary windings of the ignition coil, through the breaker points and back to the battery. As the engine rotates, the distributor shaft cam turns until the high point on the cam causes the breaker points to separate suddenly.

What is ignition coil battery?

A battery ignition system has a 6- or 12-volt battery charged by an engine-driven generator to supply electricity, an ignition coil to increase the voltage, a device to interrupt current from the coil, a distributor to direct current to the correct cylinder, and a spark plug projecting into each cylinder.

What is CI and SI engine?

The Spark Ignition (SI) engine, as its name indicates uses spark to ignite the fuel. And in Compression Ignition (CI) engine, the air is compressed within the cylinder and the heat of this compression air is used to ignite the fuel.

What is an ignition cycle?

An ignition cycle is any driving event with a completed combustion engine start.

What is the importance of distributor in the car’s ignition system?

The Importance of Distributor in the Car’s Ignition System- The distributors of your car are used to provide correct firing to the spark plugs are mostly found in the ignition system of the internal combustion engine. It contains a rotating arm as a rotor and consists of a distributor cap and distributor shaft inside it.
