Double action internal combustion-electric hybrid power system
Patent pending

The basic aim of the all hybrid cars is to reduce and/or avoid fossil fuel consumption by more than one power unit for a vehicle. Various designs of hybrid vehicles exist for how the electric motor and internal combustion engine interact with the drive train, because all of them are designed as separate engine and separate motor. The basic reason for a development of the new double action combustion-electric power system is to replies two different power units in a hybrid vehicle with a single hybrid unit.

A double action hybrid power system is a unit consists of two integrated parts:

• The first part is gasoline / petrol / ethanol / natural gas or diesel internal combustion engine.
• The second part includes one or more electromagnetic reciprocating machines (motor-generators).

The reciprocating pistons of the first part and the reciprocating plungers of the second part to a common rotatable crankshaft are connected. It is the main innovation of the new hybrid power system. This technical solution gives a reason for number of hybrid system advantages. A part of them are described below:

A standard combustion engine is required to operate over a range of speed and power, yet its highest efficiency is in a narrow range of operation. Also, an engine part (of the presented invention) designed for a reduced operating range can be more efficient than a standard engine. The battery storage and electric reciprocating motors in a common unit with a combustion engine allows the combustion engine to operate at its point of maximum efficiency, to be of a higher efficiency design, and to be smaller than non-hybrid applications. The electric motor part of the hybrid engine, as every electric motor powered by capacitors (as described in the example below), allows fast acceleration of every vehicle powered by the double action internal combustion-electric hybrid system.

The hybrid system is more compact and not so heavy in the comparison with two separate units for the same functions to power hybrid vehicles, submarines, ships and airplanes.

Because the engine recharges by reciprocating generators the battery smaller batteries are required than in an electric vehicle, as example.

The double action hybrid system uses less fuel than conventional internal combustion engines and does not have the limitations in range that have been a problem for traditional battery electric vehicles. One of the enhancements of presented hybrid system includes a computer that would optimize fuel consumption been deciding when to use the two engine parts and when the battery needs to be recharged. The computer switch reciprocating electrical machines to act as electric generators in the cases of car decelerating to convert the car kinetic energy to usable power for battery charging. Simultaneously the generators act as vehicle brake, as well.

The new invented double action reversible power system can use well known and already very well developed drive trains for standard cars powered by combustion engines.

The drivers of all cars powered by presented engine will drive them as a conventional vehicle.

Example of double action internal combustion-electric power system
In one of possible double action engine designs reciprocating plungers (pistons like) are slidingly mounded in cylinders like stators and connected to a common crankshaft.

Fixed magnets, preferably of the samarium cobalt alloy type, are mounted in the piston/s to intermittently attract and repel sequentially energized electromagnets which are mounted in the cylinder walls. For the eclectic part of the hybrid power system can be used non-magnetized materials including aluminum. A power source for the stator electromagnets includes a capacitor discharge circuit for directing electrical energy to the electromagnets.

A computerized control means regulates the timing of discharge of the capacitors and thus the timing of energizing the electromagnets. A staggered strokewise location for electromagnets which are actuating pistons operating in the same cycle is preferably provided so as to avoid the requirement for simultaneous energization of electromagnets in multiple cylinders; rather, only one layer of electromagnets at one strokewise position is simultaneously energized.
