1. Product Overview The DAM513R (also known as DAM13R in the industry) is a 1.3L OEM bare engine assembly composed of cylinder block and cylinder head without peripheral accessories. Manufactured in accordance with Dongan Power original standards, this inline four-cylinder naturally aspirated gasoline engine meets National V emission standards. It is perfectly compatible with Changan Shenqi, Hafei Zhongyi/Junyi, Changhe mini passenger and cargo vehicles as well as light mini trucks equipped with 1.3L engines. Widely applied in auto repair replacement, vehicle refurbishment and cross-border export business, every unit has passed bench cold running-in test before delivery. It can be directly installed on original vehicles without modification, greatly saving maintenance time and labor cost. 2. Core Technical Parameters

3. Core Product Advantages
Stable Durability with OEM Standard Components All internal parts including pistons, crankshaft, main and connecting rod bearings, valve oil seals and cylinder gaskets are OEM matched spare parts. The cylinder bore is precisely honed and the crankshaft is dynamically balanced. Factory cold running-in removes internal stress effectively, preventing premature oil burning, abnormal knocking and blown head gasket, making it ideal for high-frequency short-haul commercial transport. Lightweight Structure & Low Fuel Consumption The compact 1.3L small-displacement design lowers overall fuel cost for urban and inter-town transportation. Adopting timing chain design eliminates regular replacement of timing belt and reduces subsequent maintenance expenses. Plug-and-play Installation to Cut Maintenance Cost All mounting holes, bracket positions, oil and water ports are completely consistent with the original engine. No cylinder boring or secondary modification is required for direct replacement of the old engine. Compared with complete assembled engines, bare engines bring obvious advantages in procurement and labor costs. Rigorous Factory Inspection Process Each bare engine undergoes air tightness test, oil pressure test and cold trial to eliminate defects such as sand holes on cylinder block, poor valve sealing and incorrect timing alignment. A full set of assembly gaskets is delivered together for immediate installation. Wide Compatibility & Stable Supply Covers mainstream 1.3L mini vans and mini trucks from Changan, Hafei and Changhe brands. Suitable for garage replacement, second-hand commercial vehicle renovation, auto parts wholesale and cross-border bare engine export with sufficient inventory and fast delivery.
4. Application Scenarios
Overhaul replacement for repair shops: solves serious faults such as cylinder scoring, excessive oil consumption, crankshaft seizure and cracked cylinder block Power refurbishment for second-hand light cargo trucks and mini passenger vans Bulk supply for auto parts wholesalers and international engine export trade
5. Warranty & Packaging
Warranty: 6 to 12 months or 20,000 kilometers, whichever comes first Packaging: Reinforced solid wooden case, suitable for long-distance land and sea transportation to avoid collision damage during transit.
