Abstract
An internal combustion motor assembly, including an internal combustion motor, a starter and a battery. In addition, the motor assembly includes a capacitor assembly, a capacitor charging assembly and a conductive network, logic and controlled switching assembly adapted to place the internal combustion motor into one of a set of states. This set includes a first state in which the capacitor assembly is receiving charge from the capacitor charging assembly but is not electrically connected to the starter; a second state in which the capacitor assembly is electrically connected to and powers the starter; and a third state in which both the battery and the capacitor assembly are electrically connected to and power the starter. The logic and controlled switching assembly places the internal combustion motor assembly into the third state after it has been in the second state and a set of criteria is met.
