20. Technician A says that an ignition
system must generate sufficient voltage to
force a spark across the spark plug gap.
Technician B says that the ignition system
must time the arrival of the spark to
coincide with the movement of the engine's
pistons and vary it according to the
operating conditions of the engine. Who is
correct?
O a. Technician A
O b. Technician B
c. Both A and B
O d. Neither A nor B
What does a slope in the spark line represent?
a. Low secondary resistance
b. High resistance in the primary circuit
c. An incorrect air-fuel mixture
d. High resistance in both the primary and secondary circuit
Consider the following statements relevant to the ignition system of SI engine:
1. Too small a dwell angle will lead to the burning of condenser and contact points.
2. Too small a dwell angle will result in misfiring.
3. Too large a dwell angle will result in burning of condenser and contact points.
4. Too large a dwell will result in mistiring.
