D4.5
Cummins
Product Description: Cummins D4.5 Engine Series
Engineered for Efficiency and Reliability in Medium-Duty Applications
The Cummins D4.5 series represents a family of advanced 4.5-liter diesel engines, designed to deliver an optimal balance of power, fuel economy, and durability for modern medium-duty commercial vehicles. With a power range spanning from approximately 140 to 280 horsepower, this engine platform is built to meet diverse operational demands while adhering to stringent global emission standards.
The D4.5 engine is engineered to be a versatile and dependable power source for a wide range of medium-duty equipment:
Medium-Duty Trucks: An ideal powerplant for urban distribution, regional haulage, and specialized transport such as refrigerated ("green channel") logistics.
Specialized Vehicles: Commonly used in dump trucks, crane trucks, and various vocational chassis requiring reliable and responsive power.
Buses & Coaches: Suitable for city buses and intercity coaches, providing a balance of performance and economy for passenger transport.
Advanced High-Pressure Common Rail Fuel System: The engine utilizes a modern HPCR fuel system for precise injection control. This technology, such as the 1800bar system in the D4.5FE, enables superior combustion efficiency, which contributes to significant fuel savings and lower emissions.
Intelligent Performance Management: Certain variants feature a smart fuel consumption management system. This system optimizes engine operation in real-time, helping to reduce overall trip fuel costs.
Robust and Integrated Design: The engine incorporates an integrated design philosophy with fewer components, leading to a more stable structure, reduced potential failure points, and increased overall reliability.
Enhanced Low-Speed Torque: Engineered for strong pull-off power, the latest D4.5 versions offer increased low-speed torque, resulting in faster acceleration, improved gradeability, and better driving performance under load.
