The present invention employs cylinder deactivation hardware and control systems to increase the heat rejected to the engine cooling system to improve heating of an internal combustion engine and a passenger compartment of a vehicle. A first half bridge circuit is placed in a first region divided by a center line of a mounting substrate, and a second half bridge circuit is placed in a second region, and the half bridge circuits are equally formed and placed point symmetrically about the central point of the mounting substrate. One side of the insertion rod has a projecting block formed with a transverse recess. A method for forming such one-piece bodies is disclosed. This invention further discloses the manufacture of the storage canister. Next, the nascent photovoltaic cell is cut into individual sections to form a plurality of photovoltaic cells.
