At what speed does the turbocharger start working?

[AndersonLynn]

For small-displacement vehicles, the turbo starts working when the speed exceeds 60km/h. Overview: A turbocharged engine refers to an engine equipped with a turbocharger. The turbocharger is essentially an air compressor that increases intake air volume by compressing air. Working Principle: It utilizes the inertial force of exhaust gases expelled by the engine to drive the turbine in the turbine chamber. The turbine then drives the coaxial impeller, which compresses air delivered through the air filter pipe, pressurizing it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel. By correspondingly increasing fuel quantity and adjusting engine speed, the engine's output power can be enhanced.
