A »Direct fuel injection delivers fuel directly into the combustion chamber, offering more precise control and efficiency. In contrast, port fuel injection sprays fuel into the intake manifold, mixing with air before entering the chamber. Direct injection often provides better performance and fuel economy, while port injection is simpler and can be more cost-effective. Both systems have unique advantages depending on vehicle design and usage.
