1.2L DK12-10 / DK12-11 / DK12-05 Engine for DFSK, Changan, Changhe Minivan, Van, and Minibus – High-Efficiency Gasoline Powertrain
This 1.2-liter inline-four gasoline engine series—comprising the DK12-10, DK12-11, and DK12-05 variants—is engineered by Chongqing Xiaokang Power Co., Ltd., a trusted manufacturer in the automotive powertrain industry. Designed specifically for compact commercial vehicles such as DFSK, Changan, and Changhe minivans, vans, and mini buses, this engine delivers reliable performance, improved fuel economy, and compliance with stringent global emissions standards—including Euro 5 and China VI equivalents. Whether you're seeking a complete engine assembly or a long-block unit for remanufacturing or replacement, these models provide an ideal balance of durability, efficiency, and modern engineering.
The DK12-10 variant features a displacement of 1.24 liters, producing up to 65 kW (88 hp) at 6,000 rpm and delivering peak torque of 115 Nm at 4,400 rpm. It meets National V emission requirements through advanced combustion technology and electronic fuel injection systems that optimize air-fuel mixture control. The DK12-01 model, while slightly smaller at 1.21 liters, offers comparable output (64 kW / 87 hp) and is optimized for lightweight construction and efficient operation under urban driving conditions. Meanwhile, the newer DK12C version represents the most advanced iteration, offering 67 kW (91 hp), same torque output, and full compliance with National VI (equivalent to Euro 6) standards—a significant upgrade in environmental friendliness and regulatory alignment for international markets.
These engines are built using precision manufacturing techniques and incorporate innovations such as variable valve timing, low-friction components, and high-pressure direct injection systems. Their design emphasizes reduced weight without compromising structural integrity, making them particularly suitable for light-duty commercial applications where fuel efficiency and maintenance costs are critical factors. Additionally, their compatibility with various vehicle platforms ensures seamless integration into existing chassis designs, supporting both OEM production and aftermarket service needs.
Commonly used in light commercial vehicles like delivery vans, small passenger shuttles, and utility transporters, this engine family excels in city driving, rural routes, and short-haul logistics operations. Its robust architecture allows for extended service intervals and minimal downtime, which makes it a preferred choice for fleet operators and independent mechanics alike. With its proven track record in Asia and growing adoption in emerging markets, the DK12 series is positioned as a cost-effective yet technologically advanced solution for micro-mobility and urban transport solutions worldwide.
Users often highlight the smooth idling, responsive acceleration, and consistent power delivery across different RPM ranges. Many appreciate the ease of installation compared to older engine models, especially when upgrading from pre-Euro 3 systems. Maintenance is straightforward thanks to standardized connectors, accessible sensors, and modular design elements that simplify diagnostics and part replacement. While some users note initial noise levels during cold starts—typical for small-displacement engines—the overall refinement improves significantly once warmed up, ensuring a comfortable driving experience even in stop-and-go traffic.
Q: Is this engine compatible with my DFSK or Changhe van model? A: Yes, the DK12-10/11/05 series is specifically designed for use in DFSK, Changan, and Changhe minivans, vans, and mini buses. Always verify your vehicle’s VIN or engine code before purchasing to ensure exact fitment. Q: Can I install this engine myself, or do I need professional help? A: While experienced technicians can handle installation, we recommend working with a qualified mechanic familiar with engine swaps, especially regarding ECU calibration, wiring harness compatibility, and emission system integration. Q: How does this engine compare to other 1.2L options on the market? A: Compared to similar engines from competitors, the DK12 series stands out due to its higher torque output at lower RPMs, better fuel efficiency, and adherence to current emission regulations—even surpassing many European counterparts in real-world performance metrics. Q: Does it support turbocharging or hybridization? A: Currently, this is a naturally aspirated gasoline engine; however, its modular design and strong base performance make it a potential candidate for future electrification upgrades or forced induction modifications by certified tuners.
