Knowledge control: Test ‘Ignition system’

1. What is used to ignite the fuel and generate power stroke?

• spark plug
• distributor
• condenser
• battery

2. Ignition of the air-fuel mixture produces __________ that operates the spark plugs.

• electric arc
• low voltage
• high pressure
• high voltage

3. What is needed for the distributor to produce electrical signals?

• switched OFF ignition and the engine running
• switched ON ignition and the engine running
• switched ON ignition and the engine stopped
• switched OFF ignition and the engine stopped

4. By_____________, the coil can produce a high voltage output to "fire" the spark plugs.

• jumping of spark
• turning the coil current on and off
• transferring the piston
• starting the engine

5. When the ignition key is turned off, the coil stops functioning and _______

• magnetic field is produced
• generator gets disconnected from the battery
• the engine stops running
• spark jumps across the gap

6. The starting system has an electric motor that rotates _________until the engine starts and runs on its own power.

• the engine crankshaft
• the running gear
• the propeller shaft and camshaft
• the drive shaft

7. The electric starting motor gear engages a gear on ________

• the final drive
• the steering wheel
• the gearbox
• the engine flywheel

8. What is needed to replace electrical energy drawn from the battery during starting system operation?

• suspension
• the exhaust system
• the charging system
• the cooling system

9. What spins the alternator pulley, when the engine is running?

• the axle shafts
• the collapse of magnetic field
• the fan belt
• the breaker point

10. What is used to control the output of the alternator?

• a voltage regulator
• a distributor
• a condenser
• an ignition coil

11. What is the function of the electric starting motor?

• to ignite the mixture
• to rotate the engine crankshaft
• to make a spark

d) to reenergize the battery

12. What is the function of an electronic control unit?

• to increase pulses for the ignition coil
• to produces tiny electrical signals for the amplifier
• to jumps across the tip of the spark plug at the correct times
• to produce electricity for the battery

13. What happens if the ignition key is turned off?

• current jumps across the gap between the electrodes as a spark
• the ignition system supplies electricity to the spark-plugs
• the coil stops functioning and the engine stops running
• electrical energy drawn from the battery during starting system operation

Let’s finish!!!
