Sole Authorized Atomizer Racing Injectors Distributor For Australia and New Zealand
An exciting new addition to the extensive Atomizer range, the new SD220 High Impedance Fuel Injector was designed as a replacement for the popular, and now discontinued Siemens 220 Injector.
Made from billet stainless steel and hand-built in the USA, the SD220, like all Atomizer injectors, is durable, fully serviceable, 100% rebuildable and built to last. Compatible with a wide range of fuels, including gasoline, methanol, ethanol, and other flex fuels, Atomizer Flow Technology delivers an ultra-fine spray for crisp idle, fast response, precise fuel metering and efficient combustion, delivering 220 lb/hr (2433 cc/min) at 43.5 PSI (3 bar) fuel pressure.
Perfect for high-horsepower turbocharged & supercharged combos, street & race applications, including rotaries & multi-cylinder engines requiring high flow and precise control, the Atomizer SD220 offers uncompromising performance, durability, and fuel flexibility for serious racers and high-performance enthusiasts!
Key Features & Benefits
- High Flow Rate: 220 lb/hr (2433 cc/min) at 43.5 PSI, with excellent linearity and control at low duty cycles
- Typical flow at 58 PSI (4 bar) around 260 lb/hr (approximate extrapolation)
- Fuel Compatibility: Compatible with gasoline, methanol, ethanol, and other flex fuels
- Precision Engineering: Proprietary Atomizer Flow Technology ensures micro-droplet fuel delivery for efficient combustion and smooth idle.
- Durable Construction: Made from billet stainless steel for maximum strength, serviceability, and longevity.
- Plug-and-Play: High-impedance coil design is compatible with most OEM and aftermarket ECUs-no resistor packs needed.
- Hand-Built Quality: Each injector is hand-assembled, internally blueprinted, and flow-matched in a closed-loop environment in the USA.
- Rebuildable: Designed for long-term use and easy servicing, saving you money over
- Impedance: Low impedance coil (~1.6 Ohms), requiring peak and hold injector drivers or external resistors for saturation drivers
- Spray Pattern: 40 degree cone for precise fuel atomization and efficient combustion
- Response Times:
● Seat crack time approx. 0.7 ms
● Full open time: 1.25 ms
● Full close time: 1.3 ms
- Compatibility: Fits most long-style injector applications, including popular rotary
and multi-cylinder engines
Dimensions
- Overall Length: Dimensionally the same o-ring to o-ring and body length with extended tip (Siemens/Bosch long style)
- Injector Body Diameter: Standard size fitting most long-style injector applications
- Connector Type: Bosch EV1 style connector
- O-Rings: Factory fitted with double Viton upper and lower O-rings for chemical and temperature resistance
