What is a primary consideration for a fuel injected engine's discharge nozzle design?

The design of a fuel injected engine's discharge nozzle is critically focused on ensuring uniform fuel distribution across cylinders. This uniformity is essential because it directly impacts the engine's overall performance, efficiency, and emissions. If fuel distribution is uneven, some cylinders may receive more fuel than others, leading to imbalances that can cause issues like misfire, knocking, or reduced power output. A well-designed discharge nozzle creates a fine spray pattern and optimizes the atomization process, which promotes a better air-fuel mixture for combustion. This results in improved throttle response, better fuel efficiency, and reduced emissions, making uniform distribution a cornerstone of effective fuel injection design. The importance of this consideration far outweighs others, such as optimizing fuel economy or maintenance simplicity, as it fundamentally affects how effectively the engine operates as a whole.
