Product Description

This product is specifically designed for the BYD472QA 1.5L Xiaoyun plug-in hybrid专用engine in the BYD Qin PLUS DM-i. It is a core intelligent component of the engine cooling system—the electric water pump assembly. Unlike traditional mechanical water pumps, the electric water pump is intelligently controlled by the vehicle's ECU via PWM signal, enabling precise regulation of coolant flow based on real-time engine temperature demands. This "on-demand cooling" significantly improves thermal efficiency, reduces energy consumption, and effectively lowers emissions during cold starts.

The Xiaoyun 1.5L naturally aspirated engine in the BYD Qin PLUS DM-i features Atkinson cycle operation with an ultra-high compression ratio of 15.5:1 and a maximum thermal efficiency exceeding 43%. This engine incorporates advanced technologies such as an electric water pump, split cooling thermal management, and cooled EGR, surpassing Toyota's mass-produced thermal efficiency record (41%). As a core actuating component of the DM-i super hybrid system's thermal management, the electric water pump drives coolant circulation among the engine, motor controller, and battery thermal management system, ensuring all components operate efficiently within their optimal temperature ranges. Compared to traditional mechanical pumps, electric water pumps offer significant improvements in functional control freedom and efficiency potential.

As a professional manufacturer of automotive thermal management system parts, we develop and produce strictly according to BYD OEM technical standards. Using brushless DC motor design with an integrated ECU control unit, the pump communicates with the vehicle via LIN or PWM bus for precise closed-loop speed control. The product passes rigorous high-low temperature cycle tests, salt spray tests, and durability tests, with OE numbers precisely matching the original vehicle for direct replacement of faulty or aged electric water pump assemblies, restoring proper cooling system operation.
