NOVELTY - A reciprocal combustion engine has cylindrically shaped piston containing a magnetic field producing component e.g. a permanent magnet, an electromagnet, a combustion engine block having a cylindrical opening for receiving the cylindrically shaped piston, and a magnetic field inducing component e.g. a coil, contained within the engine block for inducing an electric field in proximity to the cylindrically shaped piston.    USE - Reciprocal combustion engine for vehicles e.g. hybrid vehicles.    ADVANTAGE - Achieves significant weight reduction by the optional elimination of a starting motor and or other electric motors/generators/alternators typically used with conventional hybrid designs, and by eliminating or partially eliminating complex gear box typically necessary for blending power from the internal combustion engine for conventional hybrid designs, along with the electric drive motor or motors that in combination propel the vehicle. Electricity for recharging the drive battery may be provided by regenerative operation of the electrical portion, a turbine-driven generator powered by exhaust gases, possibly eliminating the drive-line generator and reducing vehicle weight, while not adding significant drag force to the driveline, or by other alternator/generator. Increased power efficiencies may be achieved by the application of engine power in all cylinder stroke modes, whether in combustion or exhaust cycles and regardless of whether the pistons are moving in upstroke or down-stroke motion. Flexible range of combinations of power derived from fuel burning and/or electro-mechanical power generation may be achieved in single engine structure. Since various features provide for continuous engine rotation consistent with conventional combustion engines, normal usage of fan belt driven accessories may be employed, so that fan belt rotationally-driven devices, such as the cooling fan, power steering and air conditioning units may all be of the conventional type. Use of some dedicated fuel-burning cylinders and some dedicated electromotive-powered cylinders may be particularly well suited for an in-line 4-cylinder engine blocks, making initial design and follow-on production more easily accomplished. When employing Wankel engine operation, a fully functioning electric motor may be included as part of or a fully discrete cell within the engine to maximize performance or other selected operational characteristics.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a rotary combustion engine;    (2) a combustion engine exhaust driven electrical charger; and    (3) a combustion and electrically driven hybrid engine.    DESCRIPTION OF DRAWING(S) - The drawing shows the representative block diagram of electric power generation features usable with a combustion engine.
