What is the primary function of the turbocharger in a diesel engine?

The primary function of the turbocharger in a diesel engine is to boost air intake. A turbocharger enhances engine performance by forcing more air into the combustion chamber, allowing for a more efficient and powerful combustion process. This increased air intake enables the engine to burn more fuel, leading to a significant increase in power output without a corresponding increase in engine size or weight.

By compressing the incoming air, the turbocharger allows the diesel engine to operate more efficiently, ultimately improving fuel economy and lowering emissions when tuned correctly. This technology is especially valuable in diesel engines, which benefit from the high levels of torque produced at lower RPMs.
