What is one advantage of using a variable geometry turbocharger in relation to fuel metering?

Using a variable geometry turbocharger provides significant advantages in improving fuel metering by optimizing air intake across different engine speeds. This optimization means that the turbocharger can adjust the geometry of its vanes to control the flow of exhaust gases, thereby enhancing the boost pressure and air intake efficiency.

When a vehicle experiences varying engine conditions, such as acceleration or different load scenarios, the variable geometry turbocharger can adapt in real time to maintain an optimal balance between air and fuel. This leads to better combustion efficiency, as the engine can burn fuel more effectively, leading to enhanced performance and improved fuel economy.

By ensuring that the correct air-fuel mixture is achieved under various operating conditions, the variable geometry turbocharger directly contributes to more efficient fuel metering and ultimately supports the overall performance and responsiveness of the engine.
