In the ________ coil, there is one coil for every two cylinders.

In the ________ coil, there is one coil for every two cylinders.

• A. Distributor
• B. Waste spark
• C. Coil-per-plug
• D. Direct injection coil

Answer: (B)

This question tests how ignition systems can share a coil between two cylinders using a wasted-spark arrangement. In a wasted-spark setup, one coil fires two spark plugs at the same time—one cylinder on the compression stroke where the spark is useful, and its paired cylinder on the exhaust stroke where the spark is wasted. Because two cylinders are powered by a single coil, you end up with one coil for every two cylinders. This is different from coil-per-plug designs, where each cylinder has its own coil, or from traditional distributor-based setups where a single coil feeds multiple cylinders without pairing two cylinders per coil.
