TECHNICAL FIELD [0001] This invention relates to the technology of cars, construction machineries, marine vessels, and electrical generators, which achieves great lightening the engine and the purification of the exhaust gas at the same time. BACKGROUND ART [0002] A pressurizing type engine using the turbo-charger having the intercooler with the low condensation was used for the fighter aircraft in 1940. Thereafter, it was applied for the motor racing such as F1. However, there are no technologies using the turbo-charger for the purpose of lightening the engine up to now. In the past, the principal object of the turbo-charger has been the improvement of the output power, and the purification of the exhaust gas. [0003] There ware few ideas that try to use the exhaust gas in the prior art. There are only ideas such as the actuation of the turbo-charger by the exhaust gas, or the recirculation of the exhaust gas controlling burning temperature to be lower in the liner, etc. [0004] In the prior art, temperature of the exhaust gas was lowered to be appropriate for the chemical reaction using three-way catalysts. Supplying the output, the fuel, and air was set to be able to produce purification utmost by the catalyst. Therefore, a mixture ratio of the fuel of the engine could not be set most appropriate theoretically. [0005] In addition, the environmental standards and the fuel efficiency standards of cars are made strict worldwide, and the technology that saves weight of engine and purifies the exhaust gas are still incomplete. PROBLEMS TO BE RESOLVED BY THE INVENTION Harmony with Environmental Technology [0006] The present invention is aimed at lightening the engine and the purification of the exhaust gas by effectively using the exhaust gas of the high temperature and the high pressure, and contributes to the environmental measure and the reduction of the and fuel efficiency. [0007] The present invention achieves the environmental protection technologies engine for cars using hydrocarbons or alcohols as fuels. MEANS OF SOLVING THE PROBLEMS [0008] To drive the gasoline engine, air is compressed; fuel is injected, and ignited with an electric plug. To drive the diesel engine, inspired air is compressed to the ignition temperature; fuel is injected, self-ignited and exploded. Then explosion power is used as motive energy. Moreover, indirect injection type diesel engine injected mixture gas also use the explosion power. Pressure of air or mixture fuel gas injected into chambers is almost normal atmospheric pressure. In this case, length of cylinder liner needs to be the same length of the piston (from the bottom dead center to the upper dead center) in order to achieve the final compression ratio. [0009] When air or mixture fuel gas is compressed beforehand, it does not need to compress in the cylinder liner, and height of the cylinder liner and engine block can be shorten and lighten. [0010] When the prior compression is twice, the length of the compression room can be shortened in 1/2, and if it is four times, it is possible to be shortened to one-quarter. It makes length of a cylinder liner short, volume of an engine block decrease and weight of engine lighten. [0011] When the total length of the cylinder liner shortens, the width of the movement of the piston is shortens. The connecting rod connected with the crankshaft can be also shortened and lightened. [0012] If the total length of the connecting rod is shortened, turning radius and moving area of crankshaft can be decreased. Measures of enhancement for inertia force of piston or connecting rod. Size of oil pan can be shortened, height of engine block can be shortened, and weight can be lightened. [0013] Oil consumption decreases to the extent that the moving part in the entire engine decreases. Stockpile of oil in the engine can be decreased, and the reduction of weight and the reduction in the maintenance cost are achieved. [0014] In order to supply pressurized air and fuel mixture gas to liner stably, tank for temporal stock of pressured air is needed. Volume of tank is decided to keep the pressure which is set on completion of supplying the gas to liner. The tank needs to resist the 24 times the pressure loads of air and the thermal changes. The material impervious to vibration is used as the material of the tank. Further, in order to make the shapes having the stable inhalation of air or fuel mixture gas, light metals or plastics are used as the material. [0015] The intake valve and the exhaust valve of the cylinder-head are driven by the hydraulic pump and the return spring with the solenoid method. The valve operation is controlled by the microcomputer. Therefore, the mechanism of the camshaft using the complex adjuster and the limiter from the low revolution area to the high revolution area assumed to be a difficult problem conventionally becomes useless. It contributes to lightening and the improvement of thermal efficiency. [0016] The exhaust gas exhausted from the exhaust pipe is exhausted from the muffler after it drives the turbo-charger. The air pressure in the liner decreases to one air pressure almost instantaneously. Therefore, the valve operation (overlap of the exhaust bulb and the intake valve) for the improving of the inhalation performance such as the air that a present engine adopts being simplified, thermal efficiency is improved at the same time as the preventing of the blow-by of the air in the combustion chamber of the engine. [0017] A small amount of hydrocarbon is injected into the exhaust gas to reduce peroxide, at the same time the pressure of the exhaust gas is increased, and the work rate of the turbo-charger is increased. Then the required air pressure is ensured. DISCLOSURE OF THE INVENTION [0018] According to the present invention, pressurized air or fuel mixture gas with 2 to 4 times or more makes the stroke distance of the piston short. Decreasing the momentum in the compression process improves the thermal efficiency of the engine. Continue reading about Lightweight engine...
