Turbocharged diesel engines are a type of internal combustion engine that uses a turbocharger to enhance performance. The turbocharger compresses the incoming air, allowing more air and fuel to enter the combustion chamber. This results in increased power output and improved fuel efficiency compared to naturally aspirated diesel engines. These engines are commonly used in various applications, including trucks, buses, and heavy machinery. The combination of diesel fuel and turbocharging provides a high torque output, making them ideal for tasks that require significant pulling power. Additionally, they tend to produce lower emissions than traditional gasoline engines, contributing to cleaner air.
