Problems solved by technology

The valve seat port and the valve body of the traditional engine are opened inwardly. This structure is really beneficial for improving the sealing between the valve seat port (that is, the valve seat port) and the valve body (that is, the valve body). However, the inner opening valve body structure severely restricts the design of air flow, air flow area and air distribution opening time.

Embodiment Construction

[0052] Such as figure 1 The external valve body engine shown includes an intake port 1, an exhaust port 2, a combustion outer wall 3 and a combustion chamber 4, and one or more outer valve valve seat ports are provided on the combustion outer wall 3 5. The outward valve seat port 5 connects the intake passage 1 and the exhaust passage 2 with the combustion chamber 4 separately or at the same time, and corresponds to each of the outward valve seat ports 5 An outwardly-opening valve body 6 is provided. The outwardly-opening valve body 6 is controlled by the valve body timing control device 7 directly or via a connecting piece 600, and will be connected to the outer-opening valve body according to the engine timing requirements. 6 Correspondingly, the outward opening valve seat port 5 is opened and closed.

[0053] Such as figure 2 In the engine shown with a valve body with outward opening, the intake passage 1 and the exhaust passage 2 are respectively connected to the outer combu...

Abstract

The invention discloses a valve body external-open air distribution engine which comprises an air inlet channel, an exhaust passage, a combustion chamber outer wall and a combustion chamber; the combustion chamber outer wall is provided with one or a plurality of external-open air distribution seat openings which cause the air inlet channel and the exhaust passage to be respectively or simultaneously communicated with the combustion chamber; each external-open air distribution seat opening is correspondingly provided with an external-open air distribution valve body; the external-open air distribution valve body is directly controlled or through a connecting piece by a valve body timing control device. The external-open air distribution seat opening corresponding to the external-open air distribution valve body is opened or closed according to the timing requirement of the engine. The engine can reduce the loss of air distribution and flow restriction and causes the degree of air current flowing and flue gas mixing in an air cylinder to be increased, thus increasing the efficiency of the engine.

Description

Technical field [0001] The invention relates to the field of engines. Background technique [0002] How to accurately and efficiently allocate air to an engine is one of the most important technical means to improve engine efficiency and improve engine environmental protection. Therefore, research in this area is also very active. The valve seat port and valve body of the traditional engine are opened inward. Such a structure is really good for improving the seal between the valve seat port (that is, the valve seat port) and the valve body (that is, the valve). However, the internal opening valve body structure severely restricts the design of air flow, air flow area and air distribution opening time. Therefore, in order to fundamentally solve the problem of engine gas distribution, a new gas distribution method needs to be invented. Summary of the invention [0003] The invention discloses a valve body opening and distributing structure arranged on a combustion chamber wall (cy...
