* Precise Fuel Delivery: Fuel injection systems offer far more precise control over the air/fuel mixture than carburetors. They can adjust the fuel delivery based on engine speed, load, and other factors, leading to a more optimal mixture at all times. Carburetors, while they can be tuned, are mechanically limited in their ability to make these constant adjustments.
* Improved Atomization: Fuel injection atomizes the fuel more effectively, leading to better combustion and more complete burning of the fuel. This results in more power and better fuel efficiency.
* Consistent Fuel Delivery: Carburetors can be affected by gravity, fuel sloshing, and altitude changes, leading to inconsistent fuel delivery. Fuel injection systems are less susceptible to these variations.
* Better Cold Starting: Fuel injection systems often have features designed to improve cold starting, which can impact the overall performance of the engine, particularly at lower temperatures.
However, it's important to note that the *difference* in power can be relatively small in some applications, especially with well-tuned carburetors. Highly tuned carburetors on specific applications can sometimes compete, but fuel injection generally holds a considerable advantage for most applications, especially modern ones. The benefits of fuel injection extend beyond simply raw horsepower to include better emissions and drivability.
