JPH0447107A - S, c valves for four-cycle engine - Google Patents

Abstract

PURPOSE:To improve an output by arranging engine valves circular and long transversely on parts where Y-shaped intake ports of a cylinder head join exhaust ports, and providing one valve with intake and exhaust functions. CONSTITUTION:Engine valves 1 are arranged on parts where bilateral intake ports 5 join exhaust ports 6 in a shape of Y-character, and joined intake/exhaust ports 7 are opened to a combustion chamber. The intake and exhaust ports 7 are opened or closed by valves 10. The valves 1 are pipes or casted products with airtightness, having valve faces 2 and 2h as semi-circular grooves abutting the ports, and interlocked with the valves 10 and rotatably driven through free gears A.

Description

[Detailed Description of the Invention] Detailed Description of the Patent In a conventional engine, the 7 intake system and exhaust system were each independent and only supplemented their functions. However, in the present invention, by the function of the valve (1) of "New!", the valve (1)
) rotates, and by the action of the valve surface (2), the incoming gasoline passes through the intake port and is sucked into the combustion chamber (1j).

In the combustion chamber (11), the burned gasoline is transferred to the piston (12).
) rises, the opening/closing valve (8) opens, and the exhaust gas passes through the intake and exhaust passages, the 3rd passage (4), and the valve face (2) of the valve (1), which was closed in the intake area, is rotated. It opens, and as a result, the 7 intake air [1 (6)] passes through to the exhaust port (5).

In the case of conventional engines with 2 valves, 1. 1 on the exhaust side and 2 in total, but because this valve (1) can be used to reciprocate between intake and exhaust, it actually does the work of 4 valves. For example, in the case of 1 ring - 4 valves, suction is taken from two valves (8) for one explosion, but by using valve (1), 1. All four valves (8) open in the event of an explosion, allowing for inhalation, which doubles the amount of inhalation. In this way, 1. In case of an explosion, twice the amount of exhaust gas can be exhausted by 4°. In the case of a 6 cylinder, 24 valve, using this valve (1) will have the effect of 48 valves. Therefore, even with an engine of the same displacement, high output is possible.

The valve (1) is connected and supported by bearings (3) at several locations, but it can also be installed individually for each cylinder. This invention was made in May 1988.
A month.

The valve (1) was devised, but the application was filed this time. Valve (8) is an open/close valve, and valve (1) is S.

It is a C valve.

Claims (1)

[Claims] The S, C valve (1) will be referred to as valve (1) hereinafter. During intake, the valve surface (2) of the valve (1) rotates and opens, gasoline enters the intake passage (4), and the intake process begins. During the exhaust process, the valve surface (2) of the valve (1) rotates and opens, and the exhaust gas after combustion escapes to the exhaust port (5) and is exhausted. The valve (1) is an invention of a device that distributes intake air and exhaust air by rotating them to open and close them.
