Frequent question: What maintenance you expect to perform on the ignition systems?

Maintenance of the typical turbine engine ignition system consists primarily of inspection, test, troubleshooting, removal, and installation. Inspection of the ignition system normally includes the following: Ignition lead terminal inspection; ceramic terminal should be free of arcing, carbon tracking and cracks.

How do you maintain an ignition system?

Maintenance of a Conventional Ignition system

  1. Contact Breaker. Burning of the contact surfaces takes place due to constant use over a period of time, which increases the electrical resistance. …

  8. Overheating.

What type of ignition system requires maintenance?

The spark plugs are the maintenance item in the ignition system that must endure the most abuse. They thread into the engine (usually the cylinder head), protrude into the combustion chamber and must endure extreme cylinder pressures and the heat of combustion.

What is the purpose of the ignition system?

The purpose of the ignition system is to create an electric spark in the engine combustion chamber, at exactly the right time, which will ignite the mixture of petrol and air.

What cautions should be taken with ignition systems and why?

Keep these 8 safety precautions in mind when working with ignition systems.

  • Always wear OSHA-approved safety glasses when. …
  • When working on any ignition system when the. …
  • Never use your hands to pull high-tension wires. …

  • Always use the correct tools when working on.

Do electronic ignition have spark plugs?

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. … In this system, coils sit directly on top of the spark plugs (there are no spark plug wires), and the system is completely electronic.

What is a normal gap for a spark plug?

The gap setting is different for each vehicle but most are somewhere between 0.028″ and . 060″. Consult the owner’s manual or Champion ® catalog to find the recommended setting for the vehicle you’re working on.

How much resistance should a ignition coil have?

Most ignition coils should have a primary resistance falling somewhere between 0.4 and 2 ohms; however, refer to your manufacturer’s specifications for the correct reading. If a reading of zero is displayed, that signifies that the ignition coil has shorted internally in the primary windings and needs to be replaced.

What is secondary ignition system?

The secondary circuit consists of the secondary windings in the coil, the high tension lead between the distributor and the coil (commonly called the coil wire) on external coil distributors, the distributor cap, the distributor rotor, the spark plug leads and the spark plugs.

What is an ignition tune up?

What is generally considered the tune-up today is just the replacement of the spark plugs. … The next type of ignition system (mostly on older vehicles) has a distributor, coil, spark plug wires and plugs. This type of ignition system tune up normally replaces the distributor cap and rotor, wires, and plugs.

What are the five basic functions of an ignition system?

The basic components in the ignition system are a storage battery, an induction coil, a device to produce timed high-voltage discharges from the induction coil, a distributor, and a set of spark plugs.

How many types of ignition systems are there?

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 the primary ignition system?

An ignition system is a system for igniting a air-fuel mixture. … Ignition system is divided into two electrical circuits – the primary and secondary circuits. The primary circuit carries low voltage. This circuit operates only on battery current and is controlled by the breaker points and the ignition switch.

Why is it important to study about the ignition coil?

If you drive with a faulty ignition coil, the fuel will not combust properly in the chambers. This will lead to the following. Loss of gasoline through the exhaust, which leads to your car backfiring.

Which two types of igniter are used on gas turbine engines?

There are two types of igniter plugs; the constricted air gap type commonly used on gas turbine engines and the shunted surface discharge type. As the name implies, the air gap type has a larger gap between the body of the igniter and the electrode.

What precautions are necessary when removing a spark plug lead?

Always remove wire from spark plug before working on the engine or equipment.

  • Do not check for spark with spark plug removed.
  • Do not tamper with springs, links or any other parts that may increase the governed engine speed.
  • Do not modify this engine in any way.
