Original Yuchai YC4F Engine EGR Valve Motor Module FG1FC-1207242SF2 suitable for yuchai YC4FA115 YC4FA130 engine DONGFENG TRUCK
The electric motor module drives the EGR valve to achieve precise exhaust gas recirculation, optimize combustion, improve fuel economy, and meet emission regulations.
Function
1. High-precision stepless opening adjustment: An integrated high-performance DC motor, combined with a precision gear reduction mechanism or direct drive design, enables millisecond-level response and extremely high-resolution adjustment of the EGR valve from fully closed to fully open. This allows the ECU to dynamically fine-tune the exhaust gas recirculation flow based on real-time operating conditions, avoiding black smoke, power loss, or high-temperature knocking caused by "too much" or "too little" flow.
2. Closed-loop position feedback and adaptive control: The module integrates a highly reliable position sensor that continuously feeds back the actual valve opening to the ECU as an analog voltage or digital signal, forming a complete closed-loop control system. Even under conditions of slight carbon buildup, voltage fluctuations, or aging, the ECU's self-learning function automatically compensates for deviations, ensuring stable emissions compliance over long-term use.
3. High-efficiency exhaust gas recirculation and emission optimization: Its core mission is to introduce approximately 5%-30% of the inert exhaust gas from the engine exhaust into the intake side, diluting the oxygen concentration and lowering the peak combustion temperature, thereby significantly suppressing NOx formation. Simultaneously, it optimizes the in-cylinder combustion phase, reducing particulate matter and unburned hydrocarbon emissions, and to some extent improving low-speed torque and fuel economy.
4. Strong adaptability to extreme environments: It adopts an all-aluminum alloy die-cast shell + high-temperature sealing material, which can withstand the engine compartment temperature of -40℃ to +. The motor coils and circuit boards are specially insulated, with perfect short circuit and overcurrent protection. The service life is usually more than 100,000 kilometers or 3-5 years.
