| Fuel Injector |
 |
The injector atomizes a predetermined amount of fuel and delivers the fuel spray toward the intake valve based on signals from the Engine ECU. DENSO's injector generates finer fuel spray particles, significantly reducing the amount of hydrocarbon in the exhaust gas.
DENSO Technology – Leading the World
- In 1999, DENSO introduced the world’s first 12-hole (opening) fuel injector (C60) – successfully reducing the atomized particle size to 65 µm.
- In 2002, DENSO introduced a UC injector with uniquely shaped fuel injection openings. These fuel injection openings reduce the fuel spray particle size to 50 µm.
Benefits and Features
- Small fuel spray particles
- The fuel flow to the fuel injection opening in the injector is improved – reducing the particle size of fuel spray (C60, UC).
- The fuel injection opening area gradually increases, resulting in further reduced particle size of fuel spray (UC).
- High responsiveness
- Industry-leading fuel injection responsiveness due to improved magnetic circuit and lighter-weight valve.
- Small size
- Sealing by welding results in smaller injector size. (C60, UC).
