Ignition System: Description and Operation

The engine is fitted with a twin ignition system, i.e. there are two spark plugs per combustion chamber to ignite the air-fuel mixture.

This reduces in the spark travel in the cylinder and reduces combustion time while producing a faster pressure increase. In addition, a more stable combustion is achieved thanks to the second spark source, i.e. the differences between one working stroke and another are reduced.

IGNITION FINAL STAGE
A double final stage with two transistors supplies current to both ignition coils The double final stage is fitted under the left hand seat, mounted on a bracket next to the DME control unit.

In summary, twin ignition offers the following advantages:

- Higher power output than with single ignition

- Lower fuel consumption

- Improved engine idle

- Improved throttle response with a cold engine with less enrichment requirements

- Reduced emissions
