Product Description: Cummins B3.9CS4 Diesel Engine
The Cummins B3.9CS4 is a durable and versatile 4-cylinder diesel engine designed to deliver reliable power for demanding industrial and construction equipment. Built for efficiency and low total cost of ownership, this water-cooled, turbocharged engine provides a robust power solution for a wide range of heavy-duty applications.
The B3.9CS4 series offers several power ratings to suit different equipment needs. The following table summarizes the key variants and their performance data:
Note: The engine features a 4-stroke cycle, water-cooling system, and supercharged intake. It is designed to comply with the China National Standard Stage IV (equivalent to Euro IV) emission regulations.
This engine is engineered as a prime power source for various heavy-duty mobile equipment, including:
Road Construction Machinery: Such as compact wheeled pavers for tasks like road resurfacing.
Mining and Tunneling Equipment: Including hydraulic drill jumbos for underground mining and tunneling operations.
General Construction Equipment: Powering a broad range of machinery including loaders, excavators, and drilling rigs.
Advanced Emission Control: The engine incorporates a unique Exhaust Gas Recirculation (EGR) system. This design allows it to meet stringent China IV emission standards without requiring a urea-based Selective Catalytic Reduction (SCR) system, simplifying operation and reducing ownership costs.
High-Efficiency Fuel System: It utilizes a new generation of high-pressure fuel injection technology. This system enables precise injection control and fuel supply compensation, leading to higher fuel efficiency and superior fuel economy.
Robust and Durable Design: The engine benefits from a modern architecture that employs new materials and manufacturing processes. This enhances its robustness, adaptability to various fuel qualities, and overall suitability for the harsh operating environments typical of construction machinery.
