Abstract:
A miniature engine generator comprising:a cylinder head, the cylinder defining axial and radial directions, the cylinder head having a closed end and an open end, and the cylinder head having inlet and exhaust ports, a continuation of the cylinder head extending axially from the open end and constructed with a mechanical fitting placed on the continuation, means for introducing fuel and air and means for removing exhaust, means for igniting the fuel spring with integral end fittings formed from one piece, wherein one end fitting mates with the mechanical fitting thereby forming an integral cylinder head, continuation and spring assembly, and the other end fitting aligned axially to accept a rod, a piston constructed and arranged to travel reciprocally within the cylinder, the rod with a proximate end attached to the piston and extending axially in the open end direction, the distal end of the rod fixed to the spring other end fitting, a permanent magnet fixed to the continuation wherein the permanent magnet defines a gap, a coil fixed to the spring and arrange to travel within the gap, means for making electrical connections to the coil, wherein, when the motor is operating, electrical energy is available from the electrical connections.
