Advantages of B190-33 Automotive Engine
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.
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.
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.
Tailored specifically to the needs of users in the Chinese market, while ensuring excellent quality, it is more cost-effective.
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.
