HT IGNITION COIL ASSEMBLIES

BASIC PRINCIPLE

It is an induction coil in an automobile's ignition system which transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel

The wire that goes from the ignition coil to the distributor and the high voltage wires that go from the distributor to each of the spark plugs are called spark plug wires or high tension leads

An ignition coil consists of a laminated iron core surrounded by two coils of copper wire. An ignition coil has an open magnetic circuit - the iron core does not form a closed loop around the windings. The energy that is stored in the magnetic field of the core is the energy that is transferred to the spark plug

WORKING AND CONSTUCTION

The primary winding has relatively few turns of heavy wire. The secondary winding consists of thousands of turns of smaller wire, insulated for the high voltage by enamel on the wires and layers of oiled paper insulation.

When the contact breaker closes, it allows a current from the battery to build up in the primary winding of the ignition coil. The current does not flow instantly because of the inductance of the coil.

Current flowing in the coil produces a magnetic field in the core and in the air surrounding the core. Once the current has built up to its full level, the contact breaker opens.

A capacitor connected across it, the primary winding and the capacitor form a tuned circuit, and as the stored energy oscillates between the inductor formed by the coil and the capacitor

HT IGNITION COIL

INTERLOCKED LAMINATIONS

An interlocked stack of laminations for rotors or for

core for HT ignition coil wherein each lamination

includes a centrally located, circular indentation.

The indentation provides corresponding projections

and depressions in the laminas which may be

interlocked by engagement of a projection in one

lamina with an adjacent depression in an adjacent

lamina

MANUFACTURING

The laminas are blanked from continuous strip

stock and then stacked and bound together to form

the rotor or stator.

Progressive die assemblies for producing stator or

rotor laminations are well known, wherein a strip of

lamination material is fed through a sequence of

punching steps to progressively form the laminas to

the desired end configuration

TRANSFORMERS

INTRODUCTION

The wide range starts from very small transformer of 3VA

and goes up till 500KVA in various configurations like

Step up, Step down, Isolation, Auto-transformer and

Insulation Class

The normal voltage range is from few volts for electronic

application to 66KV for HT application and frequency

range varies from 50-400Hz for Iron Core application and

up to 100 KHz for Ferrite core application in single,

double and three phases.

Three phase transformers are normally made in round

coils to achieve best performance at minimum cost

PRINCIPLE AND WORKING

A transformer is a static electrical device that transfers

energy by inductive coupling between its winding

circuits

A varying current in the primary winding creates a

varying magnetic flux in the transformer's core and thus

a varying magnetic flux through the secondary winding

This varying magnetic flux induces a

varying electromotive force (emf) or voltage in the

secondary winding. Transformers can be used to vary

the relative voltage of circuits or isolate them, or both.

HORNS

(Addon engineering)

INTRODUCTION

Addon engineering was established in 1982

The company is manufacturing horns for Cars, Jeeps,

LCVs, Tractors, Trucks, Motorcycles & Scooters. The

controlling rights of Addon rest with Wings Automobile

Products Private Ltd since July 2007.

Oliver Lucas of Birmingham, England developed a

standard electric car horn in 1910.

WORKING AND PRINCIPLE

Automobile horns are usually electric, driven by a flat circular steel diaphragm that has an electromagnet acting upon it and is attached to a contactor that repeatedly interrupts the current to the electromagnet.

There is usually a screw to adjust the distance/tension of the electrical contacts for best operation

A spiral exponential horn shape is cast into the body of the horn, to better match the acoustical impedance of the diaphragm with open air, and thus more effectively transfer the sound energy. Sound levels are approximately 107–109 decibels, and current draw 5–6 amperes.
