Why do cars use Ignition Coils instead of regular block transformers?

And why don't pole transformers (pole pigs) have the same design (primary and secondary coils around the same core) as an ignition coil?Why do cars use Ignition Coils instead of regular block transformers?only ancient automobile designs still use coils

modern ones use transformers it is called direct ignition



coils operate at DC and provide about 15 KV pulse

but it is more $$$



so the answer to your question is coils are cheap







AnitaWhy do cars use Ignition Coils instead of regular block transformers?a couple of reasons.



Transformers only work on AC cars electrical system is DC



The coil works on Lenzs law principle %26gt;%26gt; in that it uses the collapsing magnetic field of the coil to generate a large Voltage spike to cause the sparkWhy do cars use Ignition Coils instead of regular block transformers?The current going to an ignition coil is "Pulsed Dc"
