Problems solved by technology

At present, the detection test for turbochargers mostly adopts the method of off-line sampling detection. The detection gas mainly used in this method is the compressed air output by the air pump. This method often cannot accurately simulate the actual practical working conditions of the turbocharger. The test results are also inconsistent with the output parameters of the turbocharger under real working conditions

Embodiment 1

[0032] The simulated exhaust gas generation system uses the simulated exhaust gas generation system to generate exhaust gas of different temperatures and compositions produced under various operating conditions of the engine, or the exhaust gas of the working engine is sent into the turbocharger, and the exhaust gas of each inlet and outlet of the turbocharger is detected air pressure, temperature and other parameters, use the computer to judge its airtightness and various performances; each test data of the turbocharger is stored in the computer, when a new turbocharger is tested, the test results The data will be compared with the data obtained from the previous test, and the basis standard for turbocharger performance judgment will be continuously revised according to the comparison results, so that the turbocharger performance judgment results obtained by this testing method will tend to be stable and accurate.

Abstract

The invention discloses turbocharger detecting and testing equipment and a turbocharger detecting and testing method. A turbocharger is placed in a sealed container equipped with a sensor, each of four air ports of the turbocharger is connected with one end of a corresponding air pipe, the other ends of the air pipes are connected with the corresponding air ports of an engine, corresponding pipeline sensors are mounted on the pipelines of the air pipes, and parameters output by the sensors are all collected and processed by a computer; the engine is equipped with different resistance runners to simulate working conditions of different road forms, the functionality of the turbocharger is judged based on data transmitted by the sensors on the pipelines, and data transmitted by the sensor in the sealed container are combined with data of the sealed container tested before an experiment to comprehensively judge the air tightness of the turbocharger. By adopting the method, the air tightness and the functionality of the turbocharger are integrally detected, so that the detection scheme is simple and the detection efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of test and detection of turbochargers for vehicles, and in particular relates to a detection technology and a judgment method for off-line detection of turbochargers of automobile engines. Background technique [0002] Exhaust gas turbocharging is the most important and widely used technology to improve the power performance of automobile engines. The turbocharger is an essential component in exhaust gas turbocharging technology. The airtightness and functional testing of turbochargers is a main way to judge the quality of turbochargers. At present, the detection test of turbocharger mostly adopts the method of off-line sampling detection. The detection gas mainly used in this method is the compressed air output by the air pump. This method often cannot accurately simulate the actual practical working conditions of the turbocharger. The test results are also inconsistent with the output parameters of the ...
