How Does a Turbocharger Work?


Quick Answer

A turbocharger gives an engine more power by increasing the amount of air and fuel the engine burns. A turbocharger is an induction system that compresses the air entering the engine. Compressed air allows the engine to push more air into the cylinders, which increases the amount of fuel used. The turbocharger enhances the combustion process inside each cylinder, which generates more power and improves the power-to-weight ratio.

The turbocharger works by using the engine’s exhaust flow to turn a turbine. The turbine inside the turbocharger spins around at 150,000 rotations per minute. This is up to 30 times faster than a standard engine. The turbocharger is designed with two primary sections that include the turbine and the compressor.

The turbine uses the turbine wheel and the turbine housing. The main function of the turbine housing is to direct the flow of exhaust gas. The energy generated by the exhaust gas is used to turn the turbine wheel. The compressor uses the compressor wheel and the compressor housing. The primary function of the compressor is to draw in air and compress it. The compressor wheel is connected to the turbine with a steel shaft that is used to turn the wheel to create a high-velocity spinning action, which draws in air and compresses it.

After this process is complete, the compressor housing converts air pressure with a process known as diffusion, and pushes the compressed air into the engine. The compressed air helps the engine burn more fuel and generate more power.
