Understanding a choke is not an easy job for even for many electronics engineers but I will try to simplify my explanantion:
A Choke coil can be defined in different ways:
- It is installed in series on a current oscillating circuit to delay the flow of this current till a certain task is finished .
- It provides a constant current source to for example an oscillatory circuit.
- It isolates a power source from a resonant circuit providing constant current flow and current delay.
That my conclusions from experience in operating and designing induction heating equipments for 10years.
As for car engine application I am not sure I know the exact application .

A choke coil is simple a magnetic core with a two terminal wire wound around it, but it must have an air gap to prevent magnetic saturation.
Induction engineering is a sho sho science that is the theory is barely tought in universities and I don't know of any website available about the theory of induction heating and its practical know how.
