The invention discloses an air inlet / outlet mechanism of a rotary air valve of an internal combustion engine, comprising an intake valve mechanism and an exhaust valve mechanism. The intake valve mechanism comprises a cylinder intake pipe and a cylinder intake valve, wherein the cylinder intake pipe is provided with an intake pipe air inlet hole communicated with a combustion chamber, and the cylinder intake valve is provided with a hole communicated with an intake pipe; and the exhaust valve mechanism comprises a cylinder exhaust pipe and a cylinder exhaust valve, wherein the cylinder exhaust pipe is provided with an exhaust pipe air outlet hole communicated with the combustion chamber, and the cylinder exhaust valve is provided with a hole communicated with the exhaust pipe. The invention is characterized in that the hole on the intake valve, which is communicated with the intake pipe, is the intake valve air inlet hole with a heteromorphic opening; and the hole on the exhaust valve, which is communicated with the exhaust pipe, is the exhaust valve air outlet hole with a heteromorphic opening. The invention has no noise, less energy loss, unobstructed air intaking and air exhausting, maximized air inlet (outlet) cross section within the limited time from starting to closing for the intake (exhaust) valve, full air exchange and strong practicability.
Description
technical field [0001] The invention belongs to a rotary circulation valve mechanism for an engine, and relates to a rotary valve intake and exhaust port mechanism of an internal combustion engine. Background technique [0002] In order to increase the intake and exhaust cross section of the internal combustion engine, improve the gas exchange efficiency of the internal combustion engine, reduce the mass of a single valve and the reciprocating inertia of the valve mechanism, the internal combustion engine gradually transitions from the traditional two valves to 3 valves, 4 valves, and 5 valves; but it is limited to the multi-valve structure Complicated, from the two aspects of performance and cost, the 4-valve engine has gradually become the mainstream of the market. In the prior art, internal combustion engine (engine) valves generally adopt reciprocating valves, but there are defects such as insufficient intake air flow and insufficient ventilation in this valve; , Some o...
