Title True or False? A spark plug with two ground electrodes will provide two separate sparks when fired.. Description True or False? A spark plug with two ground electrodes will provide two separate sparks when fired.   Why is high voltage needed to establish a spark across the gap of a spark plug? List the advantages of having one ignition coil per cylinder. Which of the following is a function of all ignition systems? a. To generate sufficient voltage to force a spark across the spark plug gap b. To time the arrival of the spark to coincide with the movement of the engine’s pistons c. To vary the spark arrival time based on varying operating conditions d. All of the above
While discussing ignition timing requirements: Technician A says that more advanced timing is desired when the engine is under a heavy load. Technician B says that more advanced timing is desired when the engine is running at high engine speeds. Who is correct?
While discussing ignition timing control in EI systems: Technician A says that when the engine coolant temperature is low, the timing is retarded until normal operating temperature is reached. Technician B says that the PCM will retard the timing during EGR operation. Who is correct? Technician Ac.Both A and B b. Technician B d. Neither A nor B
