Waste Spark Coil Wiring Diagram

Similar to our ign 1a coil but this unit has four outputs that fire in wasted spark and does not have a built in ignitor.

Waste spark coil wiring diagram. This is a typical failure on these ford waste spark ignition coils. I can take a pic of the wiring tomorrow if its any use. This is known as the waste spark method. These ignition coils have two towers providing the spark for two different cylinders simultaneously.

Understanding gm waste spark ignition part 2 duration. The wasted spark system is an ignition system used in some four stroke cycle internal combustion engines in a wasted spark system the spark plugs fire in pairs with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. 6 cylinders or coil on plug support up to 4 cylinders. Wasted spark ignition systems are a type of dis which uses one coil for every two cylinders.

If used with our bip373 ignition modules we recommend 3 0 3 5 ms dwell though you should fine tune this for your application. Pete banks explains the operation of wasted spark systems. Coil charge time adjustable. Because the coil fires the spark plug on the exhaust stroke as well it is appropriately named wasted spark ignition.

Selectable rev limiting through fuel cut or spark cut. Real time programming. Two wire idle motor control. Principles of wasted spark our virtual academy our virtual academy.

The extra spark during the exhaust stroke has no effect and is thus wasted. High speed data logging to pc at up to 60 samples per second. One cylinder is on its compression stroke and the other is on its exhaust stroke. A commonly used wasted spark coil that is retrofitted to 6 cylinder engines in australasia is the vn holden commodore chocolate block coil set.

Some engines contain ei systems that fire more than one cylinder at a time. The coil provides the spark for one of the paired cylinders on the compression stroke and to the other on the exhaust stroke. These vn coils work well in standard applications however when they are used in other vehicles most people tend to use spade terminals to connect the low tension ve and ve electrical connections. The ign 4 four tower ignition coil is an affordable option for a hot distributor less ignition.

Every waste spark pattern is superimposed. Issue with the coil is that it will still work even if wired incorrectly and will cause a random pre ignition in the inlet manifold. The coil earths through body with the bolts that hold it in place. One general purpose output.

Only 3 wires needed to make it work 12v to power the coil then 2 ign amp switch s. The waste spark in the cylinder on the exhaust stroke fires at a slightly lower voltage than the spark in the cylinder on the compression stroke.
