Abstract

The invention provides a rotor engine air passage steady flow test device. The rotor engine air passage steady flow test device comprises a rotor engine test piece, a wire harness, a CCD camera, a synchronizer, a controller, a pressure stabilizing box pressure sensor, a pressure stabilizing box, a gas flowmeter, a fan, a pipeline, a blade anemograph, a simulation cylinder sleeve, an atmospheric pressure sensor and an atmospheric temperature sensor. Based on the principle of an air passage steady flow test, stable pressure difference is generated through a fan, pressure and temperature at two ends of an air inlet of the rotor engine are measured, theoretical flow is obtained through a Bernoulli equation, actual gas flow is obtained through a gas flow meter in front of the fan, vortex is measured through a blade anemograph, the flow coefficient and the swirl ratio of the air inlet can be accurately calculated, the flow capacity of the air inlet of the rotor engine can be evaluated, the internal flow field of the rotor engine test piece is measured through the CCD camera, the capacity of the air inlet for generating in-cylinder flow is evaluated, and the design of the air inlet is guided.

Description

Technical field[0001]The present invention relates to the field of internal combustion engines, in particular, to a rotor engine airway stabilization test device.Background technique[0002]In modern internal combustion engines, air flow has a very important status. It is one of the three elements in the combustion process of the internal combustion engine, and the quality of various internal combustion engine combustion processes are different degrees, even to a large extent to the state of air, oil and gas and gas.[0003]The airflow motion in the cylinder in the intake process is very complicated. It does not only change as the crankshaft corner and the gas phase, but also along the position along the cylinder radial and axial direction; and it continues to change the flow rate and the direction of motion, the rotation center and the flow state are constantly changing.[0004]The rotor engine utilizes the rotor rotation to do work, directly output power, and removes dozens of moving pa...
