A kind of aeroengine and air intake system thereof

Abstract

The invention discloses an aero-engine and its air intake system, comprising a surge tank, a carburetor A, a carburetor B, an intake manifold A and an intake manifold B, and the middle part of the surge tank is provided with a Air inlet, the two ends of the pressure stabilizing box are respectively provided with an air outlet A and an air outlet B, the air outlet A of the pressure stabilizing box is connected to the carburetor A, and the carburetor A is connected to the inlet The gas manifold A is connected; the gas outlet B of the surge tank is connected to the carburetor B, and the carburetor B is connected to the intake manifold B, and the gas outlet A and the gas outlet B Both are provided with uniform filter screens, and protruding splitters are provided on the inner walls of the intake ends of the intake manifold A and the intake manifold B. Through the organic combination of the equalizing filter and the splitter, the aero-engine can ensure the smooth operation of the engine intake system under the requirements of limited space and light weight.

Description

technical field [0001] The invention relates to an air intake system, in particular to an air intake system of a four-cylinder horizontally opposed aero-engine. Background technique [0002] In existing four-cylinder engines, each cylinder body is usually connected with an air source respectively. Such an arrangement is suitable for the motor vehicle industry with relatively large layout space. [0003] Aeroengine air intake system is the core component to ensure efficient and stable air intake of the engine. A key indicator to evaluate the effect of engine air intake is the air flow consistency (intake uniformity) provided by the intake system to each cylinder of the engine. At present, in order to reduce the size and weight of the air intake system of an aero-engine, one air source is usually used to supply air to the four-cylinder block at the same time, or two air sources are used to supply air to the two cylinder blocks respectively. However, with such a setting, it ...

AI Technical Summary

Problems solved by technology

[0005] However, what is used in the above-mentioned patent is that the two cylinders on the left use one air source, and the two cylinders on the right use another air source. In this way, it cannot meet the lightweight requirements of the aero-engine, and when the space layout takes up too much space

When the engine operating conditions change, it cannot meet the requirements of the consistency of intake air in each cylinder of the engine

During use, there will be a phenomenon that the 3 / 4 cylinder intake air is too rich under high throttle conditions, and the 3 / 4 cylinder intake air is too lean under low throttle conditions.
