Ignition - N18: Notes

The N18 engine has an inductive ignition system with static ignition voltage distribution. Each cylinder has a separate ignition coil, which is plugged directly into the cylinder head cover.

The ignition coils transform the low-tension voltage in the vehicle's onboard electrical system into the high-tension voltage employed to ignite the air-fuel mixture within the combustion chambers. The firing order is 1-4-2-3. The engine is installed in a transverse layout.
