Description

Technical Field

[0001] The utility model relates to the technical field of fuel automobile turbocharging, in particular to a heat insulation device for an automobile turbocharger which is easy to install. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the engine output power can be increased.

[0003] Existing turbochargers have certain defects when it comes to heat insulation. It is relatively difficult to disassemble and assemble the worm gear supercharger with the heat insulation device. It is often fixed with bolts. The bolts will rust over time, causing problems such as inconvenience in disassembly, increasing the burden on the staff, wasting time and effort, and reducing the efficiency of the heat insulation installation of the turbocharger. In response to the above problems, we propose an easy-to-install automobile turbocharger heat insulation device for improvement and upgrading. Utility Model Content
