结合你对智能仪器概念的理解,讨论“智能化”的层次。
What are the two tasks of the ignition system?
A. It must create a voltage high enough (> 20,000 volts) to arc across the gap of a spark plug, thus creating a spark strong enough to ignite the air/fuel mixture for combustion.
B. It must control the timing of the spark so that it occurs at the exact right time and send it to the correct cylinder.
Please list the main components of a mechanical ignition system.
A. Ignition Switch
B. Distributor
C. Ignition Coil
D. Ignition Timing
E. Vacuum Advance
F. Ignition Wires
G. Spark Plug
