FIG. 2 is a schematic diagram of an impact cylinder of a cold air non-combustion engine according to the present invention. detailed description

It can be seen from FIG. 1 that the cold-air non-combustion engine system of the present invention has a cold-air supply device. In this embodiment, it is an air-storage tank 1. The air-storage tank 1 is connected to a pneumatic control element through an air source adjustment device 11, and a set of impacts The air cylinder 6 is connected to a crank link mechanism, and is provided with a programmer 7, the pneumatic control element and the programmer are controlled by an electronic control unit. The air source adjusting device includes The filter 10 is connected in series with the pressure reducing valve 2, the oil mist device 9, the electromagnetic directional control valve 3, and the programmer 7. The pneumatic control element includes an electromagnetic directional control valve 3, an electromagnetic throttle valve 5 and a logic element 4 connected therebetween, the oil mister 9 is connected to the electromagnetic directional control valve 3, and the electromagnetic The directional control valve 3 is connected to the electromagnetic throttle valve 5, and the electromagnetic throttle valve 5 is connected to the impact cylinder 6.

The electronic control unit obtains the engine speed, crankshaft position, and power demand signals from sensors provided on the corresponding pipelines in the engine system, and inputs them into the microcomputer ECU through the data transmission device. The electromagnetic direction control valve is determined by a program in the microcomputer ECU. The opening and closing times of the electromagnetic throttle valve 5, the logic element 4 and the programmer 7 and the gas rainbow are respectively issued to the electromagnetic direction control valve 3, the logic element 4, the electromagnetic throttle valve 5 and the programmer. Command to control the air supply timing and air supply so that the engine reaches the required power.

FIG. 2 is a schematic diagram of an impact cylinder of a cold air non-combustion engine of the present invention. The impact cylinder is a non-quick-displacement type impact cylinder, which is provided with an energy storage cavity 13 and a piston rod cavity 14. A middle cover 15 is provided between the energy storage cavity 13 and the piston rod cavity 14. 15 is provided with an openable nozzle 16 in the center. An exhaust plug 17 is provided on the middle cover. The cover bodies 18 and 19 of the energy storage cavity 13 and the piston rod cavity 14 are respectively provided with air inlet and exhaust holes 20 and 21. A piston 22 is disposed in the piston rod cavity 14, and the piston 22 has a piston rod 12 protruding outside the piston rod cavity 14. An air cleaner is preferably added to the exhaust plug 17 and the air inlet and exhaust holes 21 to purify the air.

In the present invention, the pressure of the cold air storage tank 1 may be 30 Mpa (up to 35 Mpa), and the working pressure of the pressure reducing valve 2, the oil mist device 9, the electromagnetic directional valve 3 and the programmer 7 is 20 Mpa. The working pressure of the impact cylinder is preferred, the operating pressure of the logic element 4, the electromagnetic throttle valve 5 and the impact cylinder 6 is 0.5 to 1.5 Mpa, and the required cold air source pressure is reduced by 10 times, which significantly increases safety and reliability and Economical. Ordinary cylinders can also be used. The working pressure of the logic element ⁴ , the electromagnetic throttle valve 5 and the ordinary cylinder is 5-15 Mpa, which is not safe and economical.

The working principle and process of the present invention are: when the cold air has just entered the energy storage chamber 13, the nozzle 8 is closed, the pressure of the cold air in the energy storage chamber 13 gradually increases, and when the pressure increases to the total thrust on the area of the acting nozzle, When the sum of the exhaust pressure of the piston rod cavity 14 and the frictional resistance between the piston 1 and the cylinder is exceeded, the piston 22 moves downwards, the nozzle 8 opens, and the cold air accumulated in the energy storage cavity 13 suddenly acts on the entire area of the piston 22 The pressure suddenly increased, the speed of the cold airflow at the nozzle opening reached the speed of sound, and the high-speed cold airflow at the piston chamber opening further expanded to generate a shock wave. Its frontal pressure can reach several times and dozens of times of the air source pressure. The piston 22 is subjected to a large downward thrust. Because the pressure in the piston rod cavity 14 is very low, the piston 22 rapidly accelerates under a large pressure difference. The acceleration can reach more than 1000m / s ² and it can strike downward at an average shock wave velocity of 8m / s within 0.25- 1.25s, so a large kinetic energy can be obtained.

In Fig. 2, the exhaust plug 17 is an exhaust port, a low-pressure exhaust check valve, usually a small needle valve. Its role is to vent at low pressure, that is, to communicate with the atmosphere; when it is closed at high pressure, the vent can also be used as a control signal hole.

The original combustion engine is generally composed of two mechanisms and five systems; the cold air non-combustion engine of the present invention only retains the crank connecting rod structure, and its basic composition is an air storage tank, an air source adjusting device, a pneumatic component and device, and an electronic control unit Electronically controlled. Because it is non-combustible, the gas distribution mechanism, the fuel supply system, the cooling system, and the ignition system are removed, and because the oil mist device in the air source adjustment device replaces the lubrication system, the cold air directly starts the work, and the starting system is removed. The electronic control unit can receive and process data from the electromagnetic directional control valve 3, logic element 4, electromagnetic throttle valve 5 and programmer 7 through sensors, and automatically adjust various parameters such as engine energy and speed, To achieve automatic overload protection, easy to standardize, generalize, and facilitate automatic control. The maximum combustion pressure of a gasoline engine is generally less than 5Mpa, and the maximum combustion pressure of a diesel engine is generally 5 to 9Mpa. A supercharged diesel engine may be greater than l OMpa. In order to reduce the pressure on the cylinder, an impact cylinder is specially selected, and only 10% of the cold air pressure is required 0.5 to 1.5Mpa ₀

However, the above are only specific embodiments of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, any equivalent changes and modifications made according to the scope of the claims of the application and the contents of the description should still belong to the present invention. Within the scope of the invention patent.
