Product Description

The 8235-639 is a high-performance electronic throttle actuator designed for heavy-duty CNG, LNG, and diesel engines. It provides precise air-fuel or intake control, ensuring low emissions, high efficiency, and rapid dynamic response.

Featuring a brushless, rugged design, it delivers high-torque output while minimizing wear, and communicates with the Engine Control Module (ECM) via CAN bus or analog signals for real-time position feedback and diagnostics. The actuator is IP67-rated and engineered to withstand extreme thermal, shock, and vibrational environments.

Technical Specifications

Application Scenarios

• Heavy-duty commercial vehicles (buses, trucks)

• Industrial gas engine generators

• Engines with high intake pressures or large throttle butterflies

• Marine or offshore power skids (due to IP67 and anti-corrosion coating)

This actuator is ideal for systems where high torque, rapid response, and precision control are critical, particularly in harsh or high-vibration environments.

Technical FAQ

How does CAN bus integration improve engine performance?

• Provides high-speed feedback of actuator position, temperature, and health.

• Enables closed-loop control to prevent hunting and automatically compensate for wear or environmental changes.

Can this actuator be used in marine environments?

• Yes. The IP67-rated housing and specialized coatings make it resistant to moisture, salt spray, and harsh engine room conditions.
