Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with FIGS. 1 to 7 .

[0036] This embodiment is mainly composed of an air wave supercharger 33 , a motor 6 , an electric heater 13 , an air compressor 14 , and a throttle valve 8 . When the air wave supercharger is applied on the engine, it is driven by the crankshaft of the engine. In the test system, a variable frequency motor 6 is used to drive the rotor 5 of the air wave supercharger, the motor and the rotor are driven by a belt, and the designed transmission speed ratio is 4.2. Adjusting the frequency of the variable frequency motor can adjust the speed of the air wave supercharger. Since the speed of the air wave supercharger is very high (up to tens of thousands of revolutions), and the motor is also rotating at a high speed, when installing the air wave supercharger and the motor, it should be ensured that it can run stably when it rotates. Two motor installation slots 29 and two air wave s...

Abstract

The test system for the gas wave supercharger character belongs to the gas engine field. The invention includes the gas wave supercharger, which the stator includes the inlet for high-temperature and pressure gas, the supercharging air outlet, the outlet for low-temperature and pressure gas and fresh air inlet; electric engine driving rotor. It is characterized in that: the air compressor is connected with the electric heater, the high temperature connecting conduit is between the electric heater and inlet of high-temperature and pressure; the high temperature sensor and the high pressure gas sensor are connected to the high temperature connecting conduits; the air throttle is installed at the supercharging air outlet, the air inlet connecting conduit is between the air throttle and the supercharging air outlet; the air meter, the air-inlet temperature sensor and the air-inlet pressure sensor are installed on the connecting conduit; the data of sensor is inputted into the computer by the collecting card. The invention can measure each parameter in different rotating speed and air throttle open degree.

Description

technical field [0001] The invention relates to a system for testing the performance of an air wave supercharger, which is mainly used to analyze the influence of the high-energy inlet parameters of the air wave supercharger on its performance, and then to analyze the performance of the air wave supercharger on a vehicle engine It belongs to the field of internal combustion engines, specifically the research field of superchargers. Background technique [0002] The existing air wave supercharger research at home and abroad is mainly the matching research of air wave supercharger on diesel engine and gasoline engine. At present, no performance test system has been established specifically for the air wave supercharger. In order to further study the performance of the air wave supercharger, it is necessary to build a performance test system for the air wave supercharger to study the energy transfer and flow conditions inside the air wave supercharger.
