The Woodward 8404-2033 is a specific part number within the L-Series of integrated engine control systems. This particular unit is a highly compact and specialized solution, featuring an Integrated Throttle Body (ITB) and designed for process control (which includes air/fuel ratio control).
WOODWARD 8404-2033: L-Series Integrated Throttle Body (ITB) for Process Control (50mm, Sealed)
The Woodward 8404-2033 represents a configuration within Woodward’s L-Series that combines an electric actuator, an embedded controller, and an Integrated Throttle Body (ITB) into a single, compact package. It’s specifically tailored for process control applications, often implying precise air/fuel ratio (AFR) management, and features a larger throttle body diameter.
Product Overview
- Product Type: Integrated Electric Actuator, Process Controller, and Throttle Body (ITB)
- Manufacturer: Woodward
- Series: L-Series
- Function: Primarily designed for process control, including precise air/fuel ratio (AFR) regulation in engines, by managing air flow via the integrated throttle body.
- Throttle Body Size: Features a 50 mm diameter throttle body, indicating it’s suitable for engines with higher airflow requirements compared to the 43mm ITB units.
- Design: Microprocessor-based control integrated directly into the electric actuator and throttle body assembly.
- Key Features: Sealed design, default parameters, and advanced process control capabilities.
Detailed Description
The Woodward L-Series is known for delivering advanced engine control solutions in highly integrated packages. The 8404-2033 is a specialized version that focuses on robust process control, making it ideal for applications where accurate air/fuel mixture is critical for performance, efficiency, and emissions compliance.
Key characteristics of this specific L-Series ITB include:
- All-in-One Integration: This unit combines the electric actuator (for throttle movement), the electronic controller (for processing control signals), and the throttle body (for air intake regulation) into one single, compact assembly. This simplifies installation, reduces wiring complexity, minimizes potential failure points, and saves valuable engine space.
- Dedicated Process Control: Unlike simple speed controllers, this model is designed for sophisticated process control, which often translates directly to precise air/fuel ratio control. This is vital for gaseous-fueled engines or those needing to meet stringent emission regulations while optimizing combustion.
- 50 mm Throttle Body: The larger 50 mm diameter throttle body indicates it’s designed for engines requiring greater airflow capacity, making it suitable for larger or more powerful applications.
- Sealed Design: The “Sealed” characteristic suggests enhanced protection against environmental elements like moisture, dust, and vibration, making it highly durable for harsh engine environments.
- Microprocessor-Based Control: The embedded controller uses advanced algorithms to precisely manage the throttle plate’s position based on incoming process variables (e.g., target AFR, exhaust gas readings), ensuring accurate control.
- Default Parameters: The inclusion of “Default Parameters” means it comes pre-configured for common applications, which can significantly simplify initial setup and commissioning.
- Robust and Responsive: The electric actuator provides reliable and quick actuation of the throttle plate, allowing for rapid and accurate adjustments to maintain desired process conditions.
Applications
The Woodward 8404-2033 is ideally suited for:
- Gaseous Engine Air/Fuel Ratio Control: Providing highly precise air/fuel mixture management for engines running on natural gas, propane, biogas, or other gaseous fuels, optimizing combustion efficiency and reducing emissions.
- Engines Requiring Emissions Compliance: For applications where meeting strict environmental regulations for exhaust emissions is paramount.
- Industrial Power Generation: Especially in distributed generation, cogeneration, or gas compression where efficient and clean operation of gaseous-fueled engines is critical.
- Specialized Industrial Processes: Where engines drive equipment that requires very fine control over combustion parameters.
