Abstract: A new renewable gravity, wind and solar energy engine, comprising: an engine block which houses a crankshaft, flying wheels and mechanical transmissions, a fulcrum is mounted on top of said engine block, a straight lever is mounted on the fulcrum and has connecting pins on the ends across the fulcrum; the connecting pins are connected to connecting rods, said connecting rods are connected to said crankshaft. An electric motor vehicle with wheels and loaded with heavy masses moves on the straight lever forward and backward from one end to the other end of the straight lever over the fulcrum. The heavy masses generate force at the ends of the lever which forces the connecting rods to move downward and upward reciprocally to convert lever drive into rotary movement of the crankshaft.

Abstract: A multivalve internal combustion engine which has a cluster valve system, said system comprises a cam on a camshaft, a valve stem with a valve spring, a cluster valve lever mounted on a lower end of said valve stem, said cluster valve lever has a plurality of holes and a plurality of valves. Said valves are inserted into said holes of said cluster valve lever respectively, and secured by mated nuts that are tightened by application of torque to make the cluster valve system to operate as one single valve.

Abstract: A variable intake valve for internal combustion engine comprising: A cam shaft, a valve with a valve head, a valve spring and a valve stem. A valve tappet is slidably extended into a sleeve guide between the cam shaft and the top of the upper end of the valve stem. The upper end of the valve stem is slidably extended into the valve tappet and a valve tappet spring is mounted on the top of the upper end of the valve stem. Also the upper end of the valve stem has a socket suitable to receive a locking pin. A locking mechanism mounted on the valve tappet comprises a locking pin controlled by a spring. The locking pin is slidably extended into the socket of the upper end of the valve stem when the locking mechanism is activated.

Abstract: A pre-combustion chamber for internal combustion engine according to the present invention includes a cylindrical base portion having threads providing means for threadable engagement with a combustion chamber of an internal combustion engine, and a plurality of cylindrical inlet ports having threads providing means for threadable engagement with a spark plug, a glow plug, a fuel injector and an air injector.

Abstract: A super heating glow plug according to the present invention includes a base portion having a fixing portion formed on an outer wall thereof and a terminal insulatedly provided therein and connected to an electrical source; a plurality of outwardly projected heating fins formed on the outer wall of the heating surface; a heating means, integrally connected to the base portion, having a heating surface formed on a wall surface thereof and composed of a catalyst comprising a transition material and a heating means having a resistive exothermic element connected to the element being provided adjacent.

Abstract: An improved device for separating liquid from gases and vapors passing from the crankcase of an internal combustion engine to the intake manifold thereof and allowing return of the separated liquid to the crankcase, through a conduit interconnecting the crankcase with the intake manifold, the component comprising a restricting device positioned within the conduit providing a restricted flow path in the crankcase gases and vapors.
