VEHICLE LEAK DETECTION APPARATUS AND METHOD WITH AUTOMATIC INTAKE PRESSURE REGULATION

原文（中国語）

The present disclosure provides a vehicle leak detection apparatus with automatic intake pressure regulation, comprising: an air pump; a first pipeline configured to allow air pumped by the air pump to be pumped into a test vehicle; a smoke generation unit arranged between the air pump and the test vehicle and configured to generate visible smoke in the air pumped into the test vehicle; and a check valve removably connected to the first pipeline and configured to release air after an air pressure in the first pipeline exceeds an intake pressure that the check valve can withstand so as to automatically regulate the intake pressure during vehicle leak detection.
