472QA-1000100-D1 engine sub assembly is strictly manufactured in accordance with OE original factory standards, fully compatible with multiple BYD DM-i plug-in hybrid models. Built with lightweight all-aluminum structure, this engine features excellent heat dissipation, stable power operation and superior fuel efficiency. All internal core components are precisely CNC machined to standard OE dimensions for perfect fitting. Pre-calibrated DM-i hybrid ECU parameters ensure plug-and-play installation without program rewriting and zero fault codes. Each unit undergoes strict compression test, leakage test and dynamic balance test before delivery to guarantee long-term stable performance. Equipped with professional shockproof wooden frame packaging, it resists collision and deformation during long-distance sea freight, serving as an ideal replacement for aged, oil-leaking and abnormally vibrating original engines.

1. 100% OE Precise Fit: Produced strictly based on original vehicle data, all mounting points, pipeline interfaces and harness positions are completely consistent with OE standards, realizing fully bolt-on installation without cutting or drilling.
2. Stable & Energy-Saving Performance: Adopts all-aluminum lightweight design with excellent heat dissipation, ensuring stable power output and higher thermal efficiency, effectively reducing overall fuel consumption for hybrid vehicles.
3. Excellent Leak-Proof & Durability: Equipped with high-temperature resistant fluorine rubber sealing gaskets to prevent oil and coolant leakage permanently. Precisely processed core components ensure low failure rate and long service life.
4. Zero Fault Code Installation: Factory pre-calibrated exclusive ECU parameters for BYD DM-i hybrid system. No program adjustment required after installation, no dashboard error codes.
5. Strict Quality Control: Every engine sub assembly passes professional compression test, liquid leakage test and dynamic balance test before shipment, ensuring stable quality and high driving safety.
