How does the use of a turbocharger benefit an engine?

• A. Improves the exhaust scavenging efficiency.
• B. Raises the volumetric efficiency of the engine.
• C. Causes an automatic rise in the engine R.P.M. as altitude is gained.
• D. Causes an automatic rise in engine power as altitude is gained.

Answer: (B)

The use of a turbocharger significantly enhances the volumetric efficiency of an engine. Volumetric efficiency refers to the engine’s ability to fill its cylinders with air, which is crucial for combustion. A turbocharger compresses the intake air, allowing more air to enter the combustion chamber. This increase in air density means that the engine can burn more fuel, leading to a more powerful combustion event. When an engine is turbocharged, it effectively utilizes the energy from the exhaust gases to drive the compressor side of the turbo, which forces additional air into the engine. This process allows for higher performance without increasing the engine size. Therefore, the turbocharger contributes to improved power output and efficiency by ensuring that the engine can take in more air, thus raising its volumetric efficiency. Other options either misrepresent the benefits of a turbocharger or are linked to phenomena that do not inherently result from the presence of a turbocharger in an engine. For instance, while exhaust scavenging efficiency is important, a turbocharger does not directly enhance it but rather improves the overall intake efficiency. The automatic rise in engine RPM and power with altitude is also misleading, as turbocharged engines can be designed to adjust for altitude but do not automatically increase performance in that manner without proper
