What is the purpose of atomizing in fuel injection?

The purpose of atomizing in fuel injection is to break the liquid fuel into tiny particles. This process is crucial because it enhances the combustion of the fuel within the engine. When fuel is atomized, it increases its surface area, allowing for more efficient mixing with air in the combustion chamber. This leads to a more complete and efficient burn of the fuel, improving engine performance and fuel efficiency, as well as reducing emissions.

The other choices pertain to different functions or outcomes that are not directly related to the atomization process itself. For example, while cooling engine components is important for overall engine health, it is not the role of atomization. Similarly, measuring torque and creating pressure are processes relevant to engine operation but do not describe the direct function of atomizing fuel.
