This set of IC Engine Interview Questions and Answers focuses on “Magneto Ignition System – 2”.
1. In SI engine, to obtain required firing order ___________
a) battery is installed
b) distributor is installed
c) carburettor is installed
d) ignition coil is installed
View Answer
Explanation: In SI engine, to obtain required firing order distributor is installed and not battery or ignition coil.
2. What is the standard firing order in a four cylinder petrol engine?
a) 1-2-3-4
b) 1-4-3-2
c) 1-3-2-4
d) 1-3-4-2
View Answer
Explanation: None.
3. Firing order is the order in which various cylinders of a multi cylinder engine fire.
a) True
b) False
View Answer
Explanation: None.
4. The firing order is arranged to have power impulses equally spaced, and from the point of view of balancing.
a) True
b) False
View Answer
Explanation: None.
5. The main function of a ___________ is to conduct the high potential from the ignition system into the combustion chamber.
a) spark plug
b) magneto ignition
c) battery
d) none of the mentioned
View Answer
Explanation: The main function of a spark plug is to conduct the high potential from the ignition system into the combustion chamber while magneto ignition ignites with magnetic effect and battery provides electricity.
6. The spark plug must withstand pressures up to at least __________ bar.
a) 40
b) 50
c) 55
d) 60
View Answer
Explanation: None.
7. A cold plug has a large heat transfer path and a large area exposed to the combustion gases or compared to hot plug.
a) True
b) False
View Answer
Explanation: In fact, a cold plug has a short heat transfer path and a small area exposed to the combustion gases, or compared to hot plug.
8. In CDI system a capacitor is used to store the energy.
a) True
b) False
View Answer
Explanation: In the CDI system a capacitor is used to store the energy, induction coil is not used.
9. In CDI system, the output voltage is relatively dependent of engine speed.
a) True
b) False
View Answer
Explanation: Actually, in CDI system, the output voltage is relatively independent of engine speed.
10. Ignition timing is the correct instant for the introduction of spark near the end of compression stroke in the combustion chamber.
a) True
b) False
View Answer
Explanation: None.
