Description

The present invention belongs to the technical field of airflow guidance of a kind of engine cylinder, specifically, a cylinder that can generate swirls in the airflow, increase the airflow speed, more evenly mix fuel oil and air, and increase the efficiency of the cylinder This relates to the valve structure.

FIG. 5 shows the structure and operation of a known cylinder. The cylinder main body (50) is provided with a boiler chamber (51), and the cylinder main body (50) has one air passage (52) and one exhaust passage (55) communicating with the boiler chamber (51). Each is formed. The advancing passage (52), the exhaust passage (55) and the boiler chamber (51) are communicated with each other through one valve port (53) and (56), respectively, and further to the main body (50). Valve structures (60) are provided between the air passage (52), the exhaust passage (55), and the boiler chamber (51), respectively. The valve structure (60) is provided with a conduit base (61) corresponding to the air advance passage (52) and the exhaust passage (55) of the main body (50).

A valve lever (62) slidable by the operation of a convex ring is installed on the conduit base (61). The valve lever (62) includes a piston (65) corresponding to the valve opening (53), (56) of the air advance passage (52) and the exhaust passage (55), and is opposite to one end of the piston (65). A restoring spring (66) is installed between the valve lever (62) on the side to be connected and the conduit base (61) of the main body (50). The valve lever (62) opens and closes the valve passages (53) and (56) of the advance passage (52) and the exhaust passage (55) as necessary.

After opening the valve lever (62) of the valve structure (60) through the air advance passage (52), the air enters the boiler chamber (51) of the main body (50), and the valve lever (62) enters the air advance passage. The valve port (53) of (52) is closed, the air that has entered the boiler chamber (51) is mixed with fuel oil and explosively burns, and the valve lever (62) of the valve structure (60) of the exhaust passage (55) After opening and exhausting, the valve lever (62) of the valve structure (60) of the exhaust passage (55) closes the valve port (56) again, and then the valve lever of the valve structure (60) of the advance passage (52). (62) opens again. The vehicle is driven by repeating the reciprocating operation as described above.

Generally, the fuel oil in the boiler chamber (51) of the cylinder is burnt incompletely, not only wasting the fuel oil, but also reducing the efficiency and reducing the horsepower. Furthermore, the service life of the cylinder is shortened due to the problem of carbon accumulation. For this reason, the cylinder's horsepower and service life are determined mainly by the complete combustion of the fuel oil. For the fuel oil to burn more completely, the air velocity that causes the air to enter the boiler chamber (51), and the gas and fuel oil are mixed. The degree of uniformity is particularly important. As shown in FIG. 6, in the known valve lever (62), a piston (65) having a relatively large diameter is formed at one end corresponding to the valve ports (53) and (56). Conventionally, in order to smoothly enter or discharge the air flow into the boiler chamber (51), the air flow can be guided only by forming a slightly conical surface on the surface of the piston (65). The speed at which gas enters the boiler chamber (51) could not be increased effectively. Furthermore, the airflow has no spiral effect, so the gas entering the boiler chamber (51) cannot be effectively mixed with the fuel oil, adversely affecting the usage efficiency and life of the cylinder.

In other words, the flow rate of the gas can be increased by increasing the speed at which the gas enters the boiler chamber of the cylinder. Furthermore, if the swirl effect is generated in the gas, the gas and the fuel oil can be mixed more uniformly. This allows the fuel to burn more completely and achieve the purpose of increasing the efficiency of the cylinder, thus increasing the horsepower of the cylinder and extending its service life.

It is an object of the present invention to provide a cylinder valve structure that solves the problems of the above structure. That is, the present invention is to provide a cylinder valve structure that can increase the air flow velocity of the cylinder, generate a swirl effect, and more uniformly mix fuel and gas.

In view of the problems found in the prior art, the present inventor has conducted extensive research into the valve structure of cylinders over many years, and as a result, boilers have been installed in the cylinder body.
