Firing Order and Engine Components

This video tutorial explains the ignition system, focusing on how the ignition coil and distributor work together to fire the cylinders in a four-stroke engine. It covers the firing order and engine balance, using an Acura Integra as a practical example. The video also introduces modern distributorless engines, highlighting their advantages in terms of efficiency and power.

What is the primary role of the ignition coil in the ignition system?

• To regulate engine temperature

• To convert low voltage to high voltage

• To store electrical energy

• To distribute voltage to the spark plugs

How does the rotor in the distributor function in a four-cylinder engine?

• It spins and creates a spark at contact points

• It regulates the engine's fuel intake

• It controls the engine's exhaust system

• It directly contacts the spark plugs

Which of the following is NOT one of the four strokes in a four-stroke engine?

• Exhaust

• Ignition

• Compression

• Intake

Why is the firing order important in a four-cylinder engine?

• To reduce engine noise

• To increase fuel efficiency

• To maintain engine balance

• To ensure the engine starts

In the firing order 1-3-4-2, which cylinder is in the power stroke when cylinder 1 is firing?

• Cylinder 2

• Cylinder 3

• Cylinder 4

• None of the above

What is the firing order of the Acura Integra's engine as discussed in the video?

• 1-2-3-4

• 1-3-4-2

• 4-3-2-1

• 2-4-3-1

How does the firing order contribute to the balance of the engine?

• By ensuring all pistons move simultaneously

• By alternating the firing of pistons on opposite sides

• By firing all cylinders at once

• By reducing the number of moving parts

What is a key advantage of distributorless engines over traditional systems?

• They allow for precise timing of each spark plug

• They require less maintenance

• They eliminate the need for spark plugs

• They are cheaper to manufacture

What role does the ECU play in modern distributorless engines?

• It controls the fuel injection system

• It times each spark plug precisely

• It regulates the engine's temperature

• It manages the car's braking system

What is eliminated in modern distributorless engines that was present in traditional systems?

• The distributor

• The spark plug

• The battery

• The ignition coil
