The ignition system uses a battery, ignition coil, distributor, and spark plugs to generate sparks that ignite the fuel-air mixture in the engine's cylinders. The ignition coil produces a high voltage spark via electromagnetic induction to fire the spark plugs. The distributor routes the high voltage spark to each cylinder in the proper firing sequence. Together, these components ensure the spark plugs ignite the fuel-air mixture at the optimal time for combustion.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. What is Ignition System ???
The system in an internal-combustion
engine that produces thespark
to ignite the mixture of fuel and air:
includes the battery, ignition coil,
distributor, spark plugs, and associated
switches and wiring.
3. IGNITION FUNCTION
Produces 30,000 volt spark across spark plug
Distributes high voltage spark to each spark plug in
correct sequence
Times the spark so it occurs as piston is nearing top dead
center
Varies spark timing with load, speed, and other conditions

9. BATTERY IGNITION SYSTEM
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.
Current goes from the battery through the primary
winding of the coil, through the interrupting device, and
back to the battery.
10. The primary circuit consist of the battery, ammeter, ignition
switch, primary coil winding, capacitor, and breaker points.
The function of these components are :
Battery – Provides the power to run the system
Ignition switch – allows the driver to turn the system on
and off
Primary coil – produces the magnetic field to create the
high voltage in the secondary coil.
Breaker points – a mechanical switch that acts as the
triggering mechanism
Capacitor – protects the points from burning out.
11. The Secondary circuit converts magnetic induction into high
voltage electricity to jump across the spark plug gap, firing
the mixture at the right time. The function of the components
are –
secondary coil – the part of the coil that creats the high
voltage electricity.
Rotor – spin around on the top of the distributor shaft, and
distributes the spark to the right spark plug.
spark plug – Take the electricity from the wires and give it
an air gap in the combustion chamber to jump across to light
the mixture.

13. MAGNETO IGNITION SYSTEM
The simplest formof spark ignition is that using
a magneto.
An ignition magneto, or high tension magneto, is
a magneto that provides current for the ignition system of
a spark-ignition engine, such as a petrol engine.
Theengine spins a magnet insideacoil, or, in theearlier
designs, a coil insidea fixed magnet, and also operates
a contact breaker, interrupting the current and causingthe
voltage to be increased sufficiently to jumpa small gap.
The spark plugs are connected directly from
the magnetooutput.

19. Distributorless Ignition Systems
The principles of operation are basically no different than
those for distributor equipped electronic ignition systems that
began appearing on American automobiles in 1972.
There are 2 obvious differences:
• A DI system does not have a mechanical distributor.
•Most DI systems use one coil for every two spark plugs
(however some systems have one coil per cylinder i.e.
BMW).
20. Distributorless Ignition Systems
In operation the only major difference is that DI systems fire
all of the engines spark plugs in ONE crankshaft revolution,
whereas the old mechanical distributor type fires all plugs every
TWO crankshaft revolutions.
On all four stroke engines, equipped with or with out distributors
require TWO crankshaft revolutions (720° travel) for the
combustion to occur on each cylinder.
On engines with an even number of cylinders, combustion occurs
in half of the cylinders in the first revolution (360°) and in the
other half in the second half of the revolution. Each cylinder that
has combustion in the first revolution has a companion cylinder
that fires 360° apart from it during the second revolution.
