What is the difference between compressed injector and spray injector?

A compressed injector uses pressurized air to atomize and inject fuel into the combustion chamber, often resulting in finer fuel droplets and improved mixing with air. In contrast, a spray injector directly injects fuel into the engine using a nozzle that creates a spray pattern, focusing on precise fuel delivery. While both types aim to enhance engine performance and efficiency, their mechanisms and applications can differ based on engine design and requirements.
