Electric internal combustion engine

The invention discloses an electric internal combustion engine comprising a crankshaft, a connecting rod, a piston, an air cylinder and an electric ion combustion device; the air cylinder and the piston are matched to form a combustion chamber; the electric ion combustion device is used for ionizing, igniting and thermally expanding air water molecules in the combustion chamber of the air cylinderto push the piston to do reciprocating motion; the piston is connected with the crankshaft in a hinged mode through the connecting rod; the electric internal combustion engine further comprises a battery; and the battery is communicated with the electric ion combustion device and used for providing a power source for the electric ion combustion device. The electric internal combustion engine hasthe advantages that the structure is simple, the electric ion combustion device enables air in the combustion chamber of the air cylinder to be subjected to electric ion combustion collision, then thepiston is pushed to move t
