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 smart temperature control core component integrated into the engine cooling system—the electronic thermostat assembly. The thermostat acts as a precise "smart manager," automatically regulating the flow path and volume of coolant based on the engine's operating condition, ensuring the engine always runs within its optimal temperature range, directly impacting power output, fuel economy, and engine service life.
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%, making it one of the global leaders among mass-produced engines. This engine is equipped with an advanced intelligent thermal management system utilizing electronic thermostat technology, enabling precise coolant temperature control based on engine operating conditions. Compared to traditional wax-type thermostats, the electronic thermostat offers faster response, more precise control, and lower energy consumption.
This product is developed and manufactured strictly according to BYD OEM technical standards, featuring a high-precision ECU control unit paired with a temperature sensor for intelligent regulation. It passes rigorous environmental durability tests for direct OEM replacement, restoring proper cooling system operation.
