The term "turbocharged" refers to a device or system that uses a turbine to increase the power output and efficiency of an internal combustion engine. In other words, it is a method of forced induction used in engines to improve their performance by increasing air pressure and density within the cylinders. This results in more fuel being burned which leads to increased horsepower and torque. The term "turbocharged" can also be used as an adjective to describe something that has been enhanced or improved, often referring to a product or service that is faster, stronger, or more efficient than its non-turbocharged counterpart.
