Based on technical specifications for automotive and industrial hardware, the part number **11009-R** most commonly refers to a high-performance **Fuel Injector** (specifically the 1100cc/min series) or a specialized **Gasket/Sensor Housing** depending on the manufacturer (such as DeatschWerks or Kawasaki). Below is the technical breakdown of the 11009-R electronic fuel injector, which is the most prominent "electronic part" associated with this ID. --- ## Technical Specifications: 11009-R (1100cc Injector) The 11009-R is a top-feed, high-impedance fuel injector designed for modern engine management systems. It converts electrical signals from the ECU (Engine Control Unit) into precise mechanical fuel pulses. ### 1. Core Electrical Characteristics | Parameter | Specification | | :--- | :--- | | **Coil Resistance** | 12.0 - 12.5 Ohms (High Impedance) | | **Connector Type** | USCAR (EV6) | | **Voltage Compatibility** | 8V to 18V | | **Driver Type** | Saturated (No resistor box required) | ### 2. Flow & Performance * **Flow Rate:** 1100cc/min at 3.0 Bar (43.5 psi). * **Spray Pattern:** Wide-angle atomization for improved fuel-air mixing. * **Latency (Dead Time):** Approximately 1.2ms at 14V (varies by pressure). --- ## Internal Components & Electronic Operation The "electronic" nature of the 11009-R involves the interaction between an electromagnetic coil and a precision pintle/ball valve. ### A. The Solenoid Coil Inside the 11009-R, a copper wire coil acts as an electromagnet. When the ECU grounds the circuit, current flows through the coil, creating a magnetic field that pulls the internal plunger upward against a spring. ### B. Pulse Width Modulation (PWM) The part operates via **Duty Cycle**. * It is not simply "on" or "off" in a static sense. * The ECU sends rapid electronic pulses. The longer the "on" time (Pulse Width), the more fuel is delivered. ### C. Compatibility with Control Systems Because it is **High Impedance (Saturated)**, it can be driven directly by almost any aftermarket or modern factory ECU without the risk of overheating the injector drivers. --- ## Common Applications 1. **High-Performance Tuning:** Used in turbocharged or supercharged engines requiring high fuel volume. 2. **E85 Conversions:** The electronic internals and seals are typically ethanol-compatible. 3. **Industrial Engines:** Certain variants of the 11009-R (Kawasaki series) refer to gaskets or electronic sensor seals used in small-engine voltage regulators.
