Problems solved by technology

[0002] In the existing leakage detection device of automobile fuel vapor emission system, the heating device is arranged in the oil to heat, the amount of smoke generated per unit time is small, the preheating time is long during detection, and the detection efficiency is not high. It is even impossible for a large exhaust system. detection
In addition, the cylinder body of the detection device in the prior art is made of aluminum, and the cylinder body is prone to cracks when stretched. Therefore, the cylinder body is usually a two-piece type, and the middle section of the barrel is glued together, including the bottom and side screw plugs, which are repaired with glue after welding. On the other hand, because the glue is easy to age after being heated for a long time, it will affect the service life and reliability

Abstract

The invention discloses an automobile fuel oil steam emission system leakage detection device and a manufacturing method thereof and belongs to the technical field of detection. The detection device comprises a barrel body, a barrel cover, an inner container, an air compression generation device, an air feeding pipe, a spray nozzle, a power source and a heating device. The barrel body is provided with an air outlet. Oil liquid in a heating barrel or liquid with fluorescent substances generates harmless smoke, the harmless smoke is led into an automobile fuel oil steam emission system through an exhaust hole, and leakage points of the automobile fuel oil steam emission system can be found out rapidly and accurately through the smoke or the fluorescent substances.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting an automobile exhaust system. Background technique [0002] In the existing leakage detection device of automobile fuel vapor emission system, the heating device is arranged in the oil to heat, the amount of smoke generated per unit time is small, the preheating time is long during detection, and the detection efficiency is not high. It is even impossible for a large exhaust system. detection. In addition, the cylinder body of the detection device in the prior art is made of aluminum, and the cylinder body is prone to cracks when stretched. Therefore, the cylinder body is usually a two-piece type, and the middle section of the barrel is glued together, including the bottom and side screw plugs, which are repaired with glue after welding. On the other hand, because the glue is easy to age after being heated for a long time, it will affect the service life and...
