Characteristics of Dongfeng Cummins B series and C series diesel engine
1. More fuel-efficient: from the advanced design and sophisticated manufacturing of Cummins in the United States, the fuel consumption is much lower than similar products.
2. Powerful: The design of the exhaust gas bypass valve makes the low-speed performance more perfect and the power is better.
3. Excellent reliability: The cylinder block and cylinder head adopt integrated design to prevent water leakage and oil leakage, and the parts are more than 25% less than other similar products. The failure rate is greatly reduced.
4. Lower maintenance cost: fewer parts and lower usage failures, resulting in a significant reduction in engine overall maintenance cost. Maintenance time is more than 50% less than other similar products.
5. Excellent cold start performance: equipped with intake air electric preheating setting and 6.6KW high power starter, which completely improve the cold start performance of the engine.
1. Originated from Cummins' advanced design and sophisticated manufacturing, the use of China's economic improvement, fuel consumption is 20% lower than domestic similar products.
2. The low-speed power is fully upgraded with better starting performance. Faster acceleration and stronger climbing performance.
3. A sufficient margin is reserved for the design of key components. The strength is more than 30% of other similar products. The engine life is longer.
4. Equipped with intake air electric preheating setting and 7.8KW high power starter.
Both B and C series engines meet EU Stage II emission standards.
