Description

Vortex Generator of Engine

The present invention relates to a vortex generator of an engine, and more particularly, by injecting fuel mixed with air into the combustion chamber of a cylinder with a vortex to increase combustion efficiency, as well as reducing emissions of incomplete exhaust gas. Rather, it relates to a vortex generator of an engine to reduce fuel consumption.

In general, an engine composed of a cylinder block, a cylinder head, and a cover includes a plurality of engines for introducing air through a carburetor (not shown) to the head cover 10 coupled to the upper portion of the cylinder head, as shown in FIGS. 1 and 2. Suction port 12 is provided, and one side of the suction port 12 is equipped with an exhaust port 16 so as to discharge the exhaust gas combusted in the combustion chamber 14 to the outside after the exhaust stroke. Inlet portions (12) and (16) are provided with intake valves 18 and exhaust valves 20 that can be opened and closed during fuel intake and discharge with air.

In the combustion chamber 14, a piston 22 is installed to suck, compress, explode, and exhaust the fuel introduced into the combustion chamber 14 while vertically reciprocating from the top dead center to the bottom dead center.

In the conventional engine configured as described above, when fuel mixed with air is supplied to the suction port 12 mounted on the head cover 10, the intake valve 18 mounted at the inlet of the suction port 12 opens, and the combustion chamber ( 14) As the fuel is injected into the inside and the intake valve 12 is closed, the piston 22 moves to the top dead center to compress the fuel.

Thereafter, as the ignition plug (not shown) installed in the head cover 10 is ignited, the fuel is exploded and the piston 22 is moved back to the bottom dead center to perform one stroke. At this time, the exhaust gas combusted as the exhaust bulb 16 opens is discharged to the outside air along the exhaust port 16.

However, since the fuel is injected into the combustion chamber through the suction port as described above, the fuel and air are not mixed properly, and the fuel is not distributed to the exhaust port, so that the hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) are not. Incomplete combustion exhaust gas such as) is discharged to the outside through the exhaust port to pollute the air, as well as to reduce the output of the engine and increase fuel economy.

The present invention is to solve the above problems, the present invention is connected to the intake manifold for introducing air from the surge tank to one side of the suction port, the air in the combustion chamber at the boundary between the intake port and the intake manifold This is achieved by the installation of a vortex generator which can be injected into the turbulence to discharge the complete combustion gas.

The vortex generator according to the present invention is achieved by a fixed body fixed between an intake port and an intake manifold, and a plurality of wings made of aluminum material rotatably attached to the fixed body.

Hereinafter, a preferred embodiment of the vortex generator of the engine according to the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are views showing the vortex generator according to the present invention, the suction port 12 is connected to the head cover 10 coupled to the upper cylinder head, the cap at the inlet of the suction port 12 An intake valve 18 having a spring 18a inserted therein is installed to open and close according to an interlock of a cam (not shown), and the inlet port 12 is provided with an injector for injecting fuel provided from a high pressure fuel pump. 24) is communicated.

In addition, an intake manifold 28 for introducing air from the surge tank 26 is connected to one side of the suction port 12, and an aluminum material is formed at the boundary between the suction port 12 and the intake manifold 28. Vortex generator 30 is provided, the vortex generator 30 is composed of a fixed body 34 rotatably fixed to a plurality of wings 32 to inject air into the turbulent flow in the combustion chamber 14 do.

The vortex generator according to the present invention configured as described above has a vortex provided at the boundary between the intake port 12 and the intake manifold 28 by the air flowing into the surge tank 26 equipped with the intake manifold 28. As the blade part 32 of the generator 30 rotates, air is converted into a vortex or wake form and injected to the intake valve 12 side. At this time, as the fuel is injected from the injector 24, the mixture of air and fuel is increased.

Thereafter, as the intake valve 12 is opened by the interlocking of the cam, the mixed fuel is injected into the combustion chamber 14 and the intake valve 12 is closed to move the piston 22 to the top dead center. It is compressed and the ignition plug can be ignited to completely burn fuel, thus preventing the release of incomplete combustion gases.

According to the vortex generator of the engine according to the present invention as described above, by installing a vortex generator to inject turbulent air into the combustion chamber from the surge tank at the boundary of the intake port and the intake manifold connected thereto In addition, it is possible to more actively inject properly mixed air and fuel into the combustion chamber and to reduce the emission of incomplete combustion gas as the fuel can be completely burned, thereby improving the output of the engine and improving fuel economy. Can be saved.

According to the present invention, a vortex generator is installed at the boundary between the intake port and the intake manifold connected to the turbulence to inject the air provided from the surge tank into the combustion chamber, whereby the air and fuel properly mixed into the combustion chamber can be more active. In addition to injecting fuel, the fuel can be completely burned, thereby reducing the emission of incomplete combustion gases such as hydrocarbon (HC), carbon phosphate (CO), and nitrogen oxide (NOx), thereby improving engine output. Rather, it has the effect of reducing fuel consumption.
