The conventional hybrid engine faces one major problem i.e. high cost of production. Although hybrid engines, in many sense proved to be highly efficient and environmental friendly, but high cost of production makes them less feasible and limits their applications. This problem is overcome by a new design in which instead of having Internal Combustion(IC) engine and electric motor separately, these two are incorporated under same housing. This involves a different working mechanism of electric motor which is as described below- This mechanism is applied to a normal engine which has two or more than two cylinders in any configuration or orientation. Taking example of In-line four cylinder engines as it is most widely used. In this the two cylinders work on conventional internal combustion mechanism, but the other two cylinders are electric cylinder and works on electricity. The reciprocating movement of piston is achieved by the principles of EMI(Electro Magnetic Induction).The cylinder head which generally consists of inlet and outlet valve is replaced by a coiled cylinder head or solenoid coil, (Solenoid coil is a wire tightly wound around a conductive core . When an electric current is passed through the coil, a magnetic field is created, thereby effectively forming an electromagnet. In most solenoid applications, this magnetic potential is used to perform work). When AC (alternating current, DIRECT CURRENT FROM BATTERY IS CONVERTED TO AC WITH THE HELP OF INVERTER) is passed through coils of cylinder head eddy currents are produced in piston made of conducting material or (Permanent magnets can also be used to make piston ,But permanent magnet loses its magnetic properties at high temperature thus limiting their application) when the piston is at top dead center, this eddy current has an opposite polarity to that of an cylinder head and thus the piston is pushed down with the help of electricity, and rotates crankshaft which in turn is connected to pistons of IC. The two mechanisms can work in harmony, and this complex energy and power management is controlled using advanced programmed electronic systems. This can be applied to any field where IC engines are used .There are many countries like India, China, South East Asian countries and other developing countries where electricity is still inaccessible to many parts and thus making 100 percent electric cars still a thing of future. This hybrid engine design ensures low cost of production of multi cylinder engines and proves to environmental friendly.
