Abstract
An embodiment system includes an ignition coil including a primary coil and a secondary coil, a high voltage battery selectively electrically connected the primary coil, a low voltage battery selectively electrically connected to the primary coil, and an electric and electronic element provided between the high voltage battery, the low voltage battery, and the primary coil of the ignition coil to selectively supply electric power of the high voltage battery or the low voltage battery to the primary coil.
Claims20
A system comprising:
- an ignition coil comprising a primary coil and a secondary coil;
- a high voltage battery selectively electrically connected the primary coil;
- a low voltage battery selectively electrically connected to the primary coil;
- a battery switch provided between the high voltage battery and the primary coil of the ignition coil to selectively supply electric power of the high voltage battery to the primary coil;
- and
- a diode provided between the low voltage battery and the primary coil of the ignition coil, wherein the diode is coupled so that current can flow from the low voltage battery to the primary coil of the ignition coil, but current cannot flow from the high voltage battery to the low voltage battery.

An engine comprising:
- a cylinder block;
- a cylinder head combined with the cylinder block to define a combustion chamber therein;
- a spark plug mounted in a mount hole of the cylinder head, wherein a lower portion of the spark plug protrudes into the combustion chamber;
- a center electrode provided at the lower portion of the spark plug;
- a ground electrode provided at the lower portion of the spark plug;
- an ignition coil electrically connected to the center electrode and the ground electrode and comprising a primary coil and a secondary coil, wherein the ignition coil is configured to be selectively powered from a high voltage battery or a low voltage battery by control of a controller;
- a battery switch provided between the high voltage battery and
- the primary coil of the ignition coil, wherein electric power is supplied to the ignition coil according to switching of the battery switch;
- and
- a diode provided between the low voltage battery and the primary coil of the ignition coil, wherein the diode is coupled so that current can flow from the low voltage battery to the primary coil of the ignition coil, but current cannot flow from the high voltage battery to the low voltage battery.
