Which car brand was the first to use turbocharging?

[SanValerie]

The first car brand to use turbocharging was the Swedish brand SAAB. Introduction to turbochargers: A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of exhaust gases expelled by the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then pressurizes air delivered through the air filter pipe, forcing it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed synchronize, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel, and by correspondingly increasing fuel quantity and adjusting engine speed, the engine's output power can be enhanced. Classification of automotive engine boosting technologies: Automotive engine boosting technologies can be divided into two types: supercharging and exhaust turbocharging, with exhaust turbocharging being the most widely applied due to its higher energy efficiency ratio.
