Description

Technical Field

[0002] As we all know, the working conditions of turbochargers are very bad. The temperature during normal operation can reach 1000℃. If there is residual oil on the surface of the turbocharger, it will cause the oil to burn, leading to more serious consequences, such as vehicle combustion. Therefore, during the engine manufacturing process, the turbocharger will be tested for oil residue.

[0003] The residual oil stains inside the turbocharger mainly come from the oil cavity of the core component. Therefore, how to control the residual oil inside the core component is a difficult problem that all turbocharger manufacturers must face. At present, most companies use the method of letting the core components stand to filter the oil to remove the residual oil, but the standing time is difficult to control. If the standing time is too long, it will lead to too much accumulated transit inventory, and if the standing time is too short, the oil filtering effect will not meet the requirements. Therefore, how to effectively improve the effect and efficiency of core component oil filtering has become a technical problem that turbocharger manufacturers need to solve urgently.
