Distributorless Ignition Principle of Operation Distributorless ignition system used extensively by Ford incorporates all the features of electronic. Distributorless Ignition Systems The principles of operation are basically no different than those for distributor equipped electronic ignition systems that began. The third type of ignition system is the distributorless ignition. The spark plugs are fired directly from the coils. The spark timing is controlled by an Ignition Control.

So, if there is no spark and no injector activity, the problem is likely in the crank position sensor.

No spark in one or two distributorless ignition systems that share a coil would tell you a coil has probably failed. In crank mode the dwell time is based upon a fixed number of engine angles as well as battery voltage.

DISTRIBUTORLESS IGNITION SYSTEMS

Distributorless ignition systems the run mode the dwell time is based upon engine speed and battery voltage. The transition from crank to run mode takes place at rpm. When did electronic ignition systems first start appearing o vehicles?

State the advantages of D. This is similar to cap voltage of the more conventional rotor arm. The spark produced in the compression cylinder is distributorless ignition systems not affected.

It may be noted that the spark on one of the cylinders jumps from the earth electrode to the spark plug centre, whereas in others it jumps from the centre electrode.

This is because the energy available from modern constant energy systems produces a spark of suitable quality in either direction. However, the disadvantage is that the distributorless ignition systems plugs may wear more quickly with this system.

System Components The distributorless ignition system contains three main components such as distributorless ignition systems electronic module, a crankshaft position sensor and the distributorless ignition coil.

This type of system is often known as the waste spark distribution method. In this system, each cylinder is paired with the cylinder opposite it in the firing order usuallyon 4-cylinder engines or, distributorless ignition systems V6 engines.

The ends of each coil secondary leads are attached to spark plugs for the paired opposites. In Distributorless ignition system a complete assembly of ignition coils and module is used to make the system compact and less complicated. Unlike electronic ignition system in which single ignition coil is used to generate high voltage ,DIS uses number of ignition coils i.

But the driveability symptoms caused by a weak coil or dead distributorless ignition systems will be limited to one or two cylinders rather than all the cylinders.

Many DIS systems use the "waste spark" setup where one coil fires a pair of spark plugs that are opposite one another in the firing order. Others, including the newer coil-over-plug distributorless ignition systems, have a separate coil for each spark plug.

Individual DIS coils are tested in essentially the same way as epoxy-filled square-type ignition coils.

First, isolate the coil pack by disconnecting all the leads. Set the ohmmeter in the low range, and recalibrate if necessary.

Distributorless Ignition (Automobile)

Connect the ohmmeter leads across the ignition coil primary terminals, and compare the primary resistance reading to specifications typically less than 2 ohms.

Then connect the ohmmeter leads across the coil secondary terminals and compare the secondary resistance reading to specifications typically 6, ohms. If readings are outside distributorless ignition systems specified range, the coil is defective and needs to be distributorless ignition systems.
