Abstract

The invention discloses an adjustable gas nozzle structure. The adjustable gas nozzle structure comprises a spraying pipe; the outer side of the spraying pipe is sleeved with a fixed ring; the inner diameter of the fixed ring is in interference fit with the outer side of the spraying pipe; a cylindrical support table is arranged at the lower end of the spraying pipe; the peripheral direction of the fixed ring is fixed with a connecting block; a groove is formed in the connecting block; two ends of the groove are clamped with the end parts of the cylindrical support table, and are connected with the cylindrical support table through rotating shafts; and the axis of the rotating shafts is perpendicular to the center line of the cylindrical support table. The adjustable gas nozzle structure realizes the purpose of a gas nozzle capable of adjusting the direction, and solves the problem of smaller contact area between gas and a combustion chamber in the prior art.

Description

technical field [0001] The invention relates to the field of engine gas supply, in particular to a gas-adjustable nozzle structure. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generation device, but also refers to the whole machine including the power device (such as: gasoline engine, aero engine). [0003] The injection time has a great influence on the power, economy and stability of the engine. The existing technology is to give the engine an injection advance angle at a given speed to increase the concentration of fresh charge entering the cylinder. , in order to achieve the fastest heat release rate and short combustion cycle. [0004] However, this also leads to une...
