    • The invention involves an engine that the cylinder block contains a coupled piston formed by a main piston, an external piston. The external piston is sleeved outside of the main piston and uses the rods on the two sides to connect to the heart-shape groove on the two sides of the crankshaft inside the crankcase at the bottom of the cylinder block. It moves with the main piston in an upward stroke and in a downward stroke. It forms a direct fuel injection device in the cylinder without carburetor. It does not need to add lubricants in the fuels. Besides, the engine has increased compression ratio.
