Understanding Turbochargers and Their Components
To appreciate the advantages and functionalities of bi-fuel engines, it is essential to understand how they operate and the underlying technology.
What is a Turbocharger?
A turbocharger is a forced induction system that increases the engine’s efficiency and power output by forcing more air into the combustion chamber. By utilizing the engine’s exhaust gases to spin a turbine, the turbo pulls in ambient air and compresses it. Ultimately, this design allows for a greater volume of air-fuel mixture to enter the engine.
