Ignition System Components and Functions

The video tutorial by Ben WA Dilla on 'Saturday Mechanic' covers the basics of ignition systems in cars. It starts with an introduction to the ignition system's role in starting a car, followed by a detailed explanation of the original ignition system components: the coil, distributor, and distributor cap. The tutorial then transitions to modern ignition systems, highlighting the shift from mechanical to electronic components, and concludes with advanced technologies like coil-on-plug systems, which offer improved engine control and reduced misfires.

What is the primary function of the ignition system in a car?

• To regulate the car's temperature

• To provide power to the headlights

• To start the engine by igniting the fuel-air mixture

• To control the car's speed

Which component in the original ignition system is responsible for transferring power to the spark plug?

• Distributor cap

• Fuel pump

• Alternator

• Battery

How does the coil in an ignition system increase voltage?

• By using a capacitor

• By using a series of windings

• By using a diode

• By using a resistor

What is the role of the primary winding in the coil?

• To create a magnetic field

• To decrease voltage

• To store electrical energy

• To connect to the battery

What mechanism in the distributor helps in switching the magnetic field on and off?

• A set of points

• A resistor

• A diode

• A capacitor

How does the rotor armature in the distributor function?

• It distributes the spark to the correct cylinder

• It generates electricity

• It charges the battery

• It cools the engine

What is a key feature of modern electronic ignition systems?

• They require frequent maintenance

• They are controlled by a computer

• They rely on manual timing

• They use mechanical switches

What is the advantage of coil-on-plug technology?

• It increases engine noise

• It decreases engine power

• It ensures no misfires

• It reduces fuel consumption

Why did manufacturers move away from distributor systems?

• To reduce costs

• To simplify engine design

• To increase engine size

• To improve ignition timing accuracy

What component detects the position of the camshaft in modern ignition systems?

• Distributor cap

• Camshaft position sensor

• Alternator

• Fuel injector
