Abstract

PURPOSE: A rotary cam shaft and a cylinder head are provided to reduce the friction element use such as a cylinder head valve, a spring and a valve tappet, for reducing the frictional noise caused by the engine rotation while improving the energy efficiency. CONSTITUTION: A cylinder head is formed with intake tube ways(30) and exhaust tube ways(40) at both sides and incorporates an intake cam shaft and an exhaust cam shaft(20,20-1) in the center of right and left sides respectively. The intake tube ways and the exhaust tube ways are respectively formed in the intake cam shaft and the exhaust cam shaft. The opening and closing of the intake and exhaust tube ways are carried out by the intake and exhaust sequences of pistons by connecting a pulley of a crank shaft to pulleys of the intake/exhaust cam shafts via timing belts(10,10-1), chain sprockets or gears.

Description

ROTARY TYPE CAM SHAFT AND CYLINDER HEAD}

The present invention is an application for a cylinder head of an engine driving system using oil and hydraulic pressure, and the head of an internal combustion engine using fossil fuel has a single cam shaft (SOHC) or a double cam shaft (DOHC). It is composed of components such as intake and exhaust valve, valve spring and valve tappet, and the cam shaft that rotates synchronously determines the opening and closing time of the intake and exhaust valve according to the position of the piston reaching top dead center by the rotation of the crank shaft. It is composed of members that reduce energy efficiency by adopting high intake and exhaust valve spring with high tensile force.

According to the application 10-2002-0079947, it is an engine that can replace the internal combustion engine that uses finite petroleum fuel and saves oil and water as an alternative engine that uses oil or water pressure without consuming fossil fuel. When the tank is connected to the battery and the motor pump engine, and the power is applied from the battery to drive the pump, the engine is driven by the oil / water pressure discharged from the pump. The above-described oil / hydraulic engine has a rotational force at the suction pressure of liquid in its structure, and the head intake and exhaust port of an existing internal combustion engine has a narrow moving flow rate due to a narrow opening and closing space of the intake and exhaust valves. In order to use as a driving source, the head structure of a general-purpose internal combustion engine does not allow high rotational force to be achieved.

As described above, the head of the internal combustion engine is considerably occupied by the obstacles to reduce the energy consumption efficiency due to the frictional force of each part, but the present invention applies a double cam shaft by dividing it into an intake cam shaft and an exhaust cam shaft. , Suction. Remove parts such as exhaust valves and springs, install the cam shaft inside the cylinder head, and open the intake exhaust pipe passage on the left and right side of the head and the intake exhaust passage through the cam shaft. OFF), the general operation of the three-cylinder internal combustion engine showed that 1 explosion 3 exhaust 2 compression 1 stroke, 2 explosion 1 exhaust 3 compression 1 stroke, 3 explosion 2 exhaust 1 compression The rotational force is generated by the repetition of one stroke, and in the case of four cylinders, it is repeated in the order of 1 explosion, 2 exhausts, 3 compressions and 4 suctions in the order of 1-3-4-2. It is structured to get driving force

.

However, the present invention is driven by the rotational force of 1 cycle per crank shaft rotation by the repeated action of three cylinders, for example, 1 suction-3 discharge, 2 suction-1 discharge, and 3 suction-2 discharge.

In the above-described intake and exhaust operation of the camshaft, the two cylinders are set at a top dead center (hereinafter, top dead center) where the first piston reaches the top dead center 110 according to the number of pistons applied to the engine (Fig. 1). 20) Cam shaft 1-1 suction pipe passage is opened so that oil or water pressure flows into the piston cylinder to lower the piston, and the liquid that has flowed into the piston cylinder by opening 2-2 discharge pipe passage of 20-1 in FIG. B) The gas is discharged as the piston rises. According to this, the opening and closing timing of the camshaft at the top dead center should be opened and closed at an angle of 180 degrees.

The three-cylinder camshaft should open and close the passageway at an angle of 120 degrees from the top dead center.

The four-cylinder camshaft should open and close the passageway at an angle of 90 degrees from the top dead center.

The 5-cylinder camshaft should open and close the passageway at an angle of 75 degrees from the top dead center.

The six-cylinder camshaft has to be opened and closed at an angle of 60 degrees from the top dead center, and the inlet and exhaust camshafts are penetrated by their respective throughways, so the above detailed working angle is 2/1. With the above configuration, the opening and closing time of the open shaft of the camshaft is determined by the number of engine cylinders, the crank structure, and the intake and exhaust sequence, and the passage of the opening and closing angle is determined in proportion to the upper and lower angles of the piston top dead center. Since the installation angle of the through passage is reduced, there is a disadvantage that the outer diameters of the head and the camshaft must be increased.

For example, in the case of three cylinders, when liquid or gas flows into the suction pipe 30 (1-1) through-path of FIG. 1, (1-1) of the suction cam shaft 20 is opened, and the inflow pressure into the cylinder 1 is increased. Generated and pushes the piston to the bottom dead center. At this time, the liquid or gas that has flowed into the cylinder No. 3 rises of the piston and opens the exhaust pipe passage 3-3 of the exhaust cam shaft 20-1, and the exhaust pipe passages 40 and 3 -3) is discharged through the circulation flow into the oil and water storage tank not shown
