Problems solved by technology

[0004] However, the vehicle power system, especially for special vehicle power systems, has a limited cooling source, generally above 40°C, and electronic components are also generating heat as power consumption units under variable working conditions. Combined with its layout and structural size and other restrictions, there is a certain difficulty in heat insulation

Abstract

The invention provides a heat-insulating control device for an electric control adjusting valve of an engine turbocharger. The heat-insulating control device comprises a shell heat-insulating structure for containing a bottom opening of the adjusting valve, a bottom layer heat-insulating layer structure, a fixing support and the like; the bottom layer heat-insulating layer structure is arranged between the bottom of the shell heat-insulating structure and the fixing support; the outer layer of the shell heat-insulating structure is provided with a composite heat-insulating layer; an air heat-insulating layer is formed between the composite heat-insulating layer and the outer layer of the shell heat-insulating structure; and the shell heat-insulating structure is provided with an exhaust port fastening outlet, a gas inlet fastening outlet and a wire opening fastening outlet which are matched with a gas inlet, an exhaust port and a wire opening of the adjusting valve and sealed for heatinsulating through sealing heat-insulating rings correspondingly. Compared with the prior art, the heat-insulating control device has the following advantages that the heat-insulating control device has the characteristics of being compact in structure, convenient to disassemble and assemble, obvious in heat-insulating effect, safe and reliable in performance, high in universality and the like, and the heat insulating problem can be effectively solved under existing conditions.

Description

technical field [0001] The invention belongs to the field of dozens of piston internal combustion engines, and in particular relates to a heat insulation control device for an electronically controlled regulating valve of an engine turbocharger. Background technique [0002] Due to its advantages in increasing engine power, reducing fuel consumption and improving emissions, exhaust gas turbochargers are currently widely used in the fields of vehicles, ships, and construction machinery. With the relentless pursuit of better economic performance, higher engine power density and stricter emission regulations, ordinary single-stage turbochargers can no longer meet the working requirements of the engine in all working conditions and in all geographical environments, especially For vehicle engines with a large range of operating conditions, it is necessary to use a blow-off valve turbocharger (WGT), a variable nozzle turbocharger (VNT), a two-stage (multi-stage) adjustable superch...
