Lightweight engine

Abstract

Weight saving of industrial engines. Making pollution-causing material harmless. Improvement in thermal efficiency and reduction of operating cost. Arrangement To produce compressed air, air is pressurized by a turbo charger or a super turbo charger and stored in an air tank. The air is fed, at an optimum temperature and a given pressure, to a cylinder liner shortened according to the pressure. Valves for taking in and out air are hydraulically driven for individual opening and closing according to a computer-aided optimum valve timing diagram. The engine is controlled under high-oxygen high-temperature lean burn condition, and a hydrocarbon is injected into an exhaust manifold to reduce peroxides, thus making pollution-causing material harmless. Effects Reduction of operating cost. Increase in carrying capacity due to the weight reduction of the vehicle body in the case of a vehicle-mounted engine.

1 . An engine having structure to shorten the total length of piston and liner by inhalation of the 2-4 times compressed air or the mixed fuel gas as planned and heated, into the liner, with the constant temperature and pressure.  
   
   
       2 . An engine according to  claim 1  having structure to reduce the movement area of crankshafts by shortening radii of gyration of crankshafts, and to reduce weight of crankshaft.  
   
   
       3 . An engine according to  claim 1  having structure to lighten its own weight of engine by using shortening liners and shortening radii of gyration of crankshaft to shorten cylinder block.  
   
   
       4 . An engine according to  claim 1  having structure to reduce the engine weight and the crankshafts, decreasing of the capacity of the oil pan, and the decreasing of the lubricating oil.  
   
   
       5 . An engine according to  claim 1  having structure to place the air tank which stores compressed and heated air or the mixed fuel gas temporarily under given conditions and to make the gases inhale into cylinder liner.  
   
   
       6 . An engine according to  claim 1  having a form of compressor for compressing the air or the mixed fuel gas to 2-4 times or more as the specified pressure, structure of valve for controlling a constant temperature of the compressed air or mixed gas and provision into the tank for storing temporarily, and structure of the temperature regulator.  
   
   
       7 . An engine according to  claim 6  having structure to operate the temperature regulator according to  claim 6 , comprising; 
 infusing the natural gas or the hydrocarbon gas such as petroleum gas into the peroxidized exhaust gas with high temperature through the infusion tube and mixing evenly,    reacting the environmentally harmful peroxidized nitrogen gas and carbon sulfide particle with the carbon molecules and the hydrogen molecules, reducing and resolving into clean nitrogen gas, water vapor, and other harmless gases, and    pressing the exhausted gas.    
   
   
       8 . An engine according to  claim 1  having the technology that enables the improvement of degree of freedom of the valve operation at the same time as the simplification of the cylinder head by controlling the movement of the induction valve and the exhausted valve by driving oil-hydraulic pump, operating the valve by in-vehicle microcomputer in faithful accordance with the planned diagram, and not using valve operation by the camshaft.
