Understanding Fuel Injection Systems
Fuel injection is the process of introducing fuel into an engine's combustion chamber. Unlike older carbureted systems, fuel injection provides a more accurate and efficient means of delivering fuel. Bosch has been at the forefront of this technology since its inception, creating systems that adapt to various driving conditions and requirements.
The Evolution of Fuel Injection Technology
1. Mechanical Fuel Injection: Early systems relied on mechanical pumps and injectors, which worked based on engine speed and load. While functional, these systems lacked precision and adaptability.
2. Electronic Fuel Injection (EFI): The advent of electronic controls revolutionized fuel injection. EFI systems use sensors and electronic control units (ECUs) to optimize fuel delivery in real-time.
3. Direct Injection: Bosch's direct injection technology injects fuel directly into the combustion chamber at high pressure, allowing for better atomization and more efficient combustion.
4. Dual Injection Systems: Combining both direct and port fuel injection, these systems maximize efficiency and performance across various driving conditions.
