| 发明名称 | Deposition prevention method and turbocharger | ||
| 摘要 | The present invention is a deposition prevention method of coking deposits using a turbocharger (120) including a turbine (122) including a flow path section having a vane section, a nozzle, and a housing, and a compressor (124) configured to introduce air into an engine (110) using rotation of the vane section of the turbine, and installed at an exhaust path (202) of the engine. The method includes a film coating process of forming a film including an element having a standard free energy change in a carbonization reaction of −50 kJ/mol or more on at least one surface of the vane section, the nozzle and the housing of the flow path section of the turbine. | ||

| 主权项 | 1. A method of preventing deposition of a carbide having been generated by an organic compound in a fuel or a lubricant, on a surface of a flow path section of a turbine of a turbocharger in an internal combustion engine, the flow path section of the turbine having a vane section, a nozzle, and a housing, and the turbocharger including a compressor configured to introduce air into the engine and to be driven by a rotation of the vane section of the turbine during an engine operation, the method comprising: forming at least one surface of the vane section, the nozzle and the housing of the flow path section of the turbine with a film of Nickel to prevent the deposition of the carbide having been generated by the organic compound in the fuel or the lubricant. | ||
