Turbocharged Direct Injection (TDI) is an advanced engine technology that combines a turbocharger with direct fuel injection. The turbocharger compresses air entering the engine, allowing for more air and fuel to be burned, which increases power and efficiency. This process helps improve performance while reducing emissions. Direct injection means that fuel is injected directly into the combustion chamber at high pressure, leading to better fuel atomization and combustion. This results in improved fuel efficiency and power output compared to traditional fuel injection systems. TDI is commonly used in modern vehicles to enhance performance and reduce environmental impact.
