As part of EMAC, DuraMac provides complete powertrain that integrated with DCEC engine, Fast-Eaton clutch, FAST-CAT transmission, DANA axle and Komman air suspension, while the electrification of automobile is the certain future, Duramac also get involved with EV powertrain system. We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.

DCEC B series electronic automotive engine can reach upto EU Stage VI emission standard, the number 30/40/50/60 are the emission standard mark of engine, which means engine emission standard are EU Stage III, IV, V, VI. For different emission standard DCEC B electronic series automotive engine, the engine itself are the same, the major different are the after-treatment system and ECU program, EMAC will keep updating products introduction page of different emission standard version engines, welcome to subscribe our website to get latest update information.

If you are in need of engine model that not available on our website for the moment, please contact EMAC sales team for technical details and related documents, our well trained sales and engineering team will help you with all products and techical documents available here at DCEC.

1.Adhering to the proven reliability of DCEC B series engines, advanced design makes parts and components less than other similar engines by more than 25%, and the engine failure rate is much lower than other similar products.
2.Adopt imported Japanese Denso high pressure common rail fuel system, with injection pressure up to 1800bar, higher injection accuracy, fuller fuel atomization, lower fuel consumption, and improved cold start performance.
3.The advanced design makes the engine parts and components extremely versatile, and the versatility with mechanical B engine parts reaches 80%, which greatly improves the availability of maintenance spare parts.
4.Tailored specifically to the needs of users in the Chinese market, while ensuring excellent quality, it is more cost-effective.
5.The low-speed torque of the engine is greatly improved, the large torque range is wide, the whole vehicle accelerates fast, and the mountain driving is also abundant.
6.The multiple electronic control functions of the engine make the driving of the whole vehicle easier and more convenient, and the decoration cover is added to further reduce the engine noise and improve the driving environment.
7.The appearance of the engine is slightly different from that of the mechanical B machine, and it is easier to upgrade the whole vehicle to National III and National IV.
8.The engine is equipped with an intake air preheating device, and it can start smoothly even at -35°C.
