How does fuel injection compare to carburetion in terms of engine efficiency?

Fuel injection allows for a more precise fuel-air mixture compared to carburetion, making it the superior choice for engine efficiency. This precision in fuel delivery is crucial as it allows the engine management system to adjust the fuel injection based on various operational conditions such as load, temperature, and throttle position. By optimizing the fuel-to-air ratio, fuel injection enhances combustion efficiency, leading to better power output and reduced emissions.

In carbureted systems, fuel is mixed with air mainly through the venturi effect, which can be less precise, especially under varying engine demands. This can result in a less efficient combustion process as the air-fuel mixture may not be optimal across all operating conditions. Therefore, fuel injection not only improves efficiency but also enhances performance, contributing to better overall engine operation.
