Why don’t Japanese cars use turbocharging?

Turbocharged engines are basically used by French cars and German cars, but Japanese cars are rarely used because Japanese cars do not need engines with strong power output, and naturally aspirated engines are generally used. .

　　

A turbocharged engine is an engine that uses a turbocharger, which is equivalent to an air compressor, which increases the intake air volume of the engine by compressing air. The turbocharged engine can increase the output power when the working state remains unchanged, and the working efficiency of the engine with the same displacement is higher than that of the naturally aspirated engine. The speed of the exhaust gas discharged from the engine and the speed of the turbine increase at the same time, causing the impeller to compress more air into the cylinder of the engine, resulting in an increase in the pressure and density of the air in the cylinder, thereby burning more fuel, increasing the speed of the engine, and increasing the output of the engine power.
