"IGNITION SYSTEM

1. General
A DIS (Direct Ignition System) is used. The DIS improves ignition timing accuracy, reduces high-voltage
loss, and enhances the overall reliability of the ignition system by eliminating the distributor.
The DIS is an independent ignition system which has one ignition coil (with an integrated igniter) for each
cylinder.

The DIS provides 6 ignition coils, one for each

to spark plugs, are integrated with the ignition coil.
Also, an igniter is enclosed to simplify the system.
