1F1-8 M162 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

(1-6 or 2-5 or 3-4). The spark occurs simultaneously in

the cylinder coming upon 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 tofire the spark plug. The

remaining energy is available to the spark plug in the

cylinder on the compression stroke.

IGNITION SYSTEM

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).
