1F2-8 M161 ENGINE CONTROLS

This ignition system does not use a conventional

distributor and coil. It uses a crankshaft position sensor

input to the Engine Control Module (ECM). The ECM

then determines Electronic Spark Timing (EST) and

triggers the electronic ignition system ignition coil.

This type of distributorless ignition system uses a

''waste spark" method of spark distribution. Each

cylinder is paired with the cylinder that is opposite it

(2-3 or 1-4). The spark occurs simultaneously in the

cylinder coming up on the compression stroke and in

the cylinder coming up on the exhaust stroke. The

cylinder on the exhaust stroke requires very little of

the available energy to fire the spark plug. The remaining

energy is available to the spark plug in the cylinder on

the compression stroke.

These systems use the EST signal from the ECM to

control the EST. The ECM uses the following

information:

Engine load (mass air flow sensor).

Engine temperature.

Intake air temperature.

Crankshaft position.

Engine speed (rpm).
