250+ TOP MCQs on Magneto Ignition System – 1 and Answers

IC Engines Multiple Choice Questions on “Magneto Ignition System – 1”.

1. In magneto ignition system, as the engine speed increases the flow of current ____________
a) decreases
b) remains constant
c) increases
d) none of the mentioned
Answer: c
Clarification: In the magneto ignition system, engine speed is directly proportional to current rate, so, as the engine speed increases the flow of current increases.

2. With magneto there is no starting difficulty.
a) True
b) False
Answer: b
Clarification: In fact, With magneto there is always a starting difficulty and sometimes a separate battery is needed for starting.

3. The magneto is best at high speeds and therefore is widely used for sports and racing cars, aircraft engines. etc.
a) True
b) False
Answer: a
Clarification: None.

4. In two wheelers magneto ignition system is favoured due to ____________ weight and less maintenance.
a) light
b) heavy
c) light & heavy
d) none of the mentioned
Answer: a
Clarification: The magneto ignition system is light weight and requires less maintenance due to which it is preferred in two wheelers.

5. The main advantage of the high tension magneto ignition system lies in the fact that the wirings carry a very high voltage and thus there is a strong possibility of causing engine misfire due to leakage.
a) True
b) False
Answer: b
Clarification: No, but the main disadvantage of the high tension magneto ignition system lies in the fact that the wirings carry a very high voltage and thus there is a strong possibility of causing engine misfire due to leakage.
