This versatility ensures that fleets and operators have access to a high-performance solution tailored to their specific needs.
Enhanced Displacement and Performance
One of the key upgrades in the B7.2 diesel engine is its increased displacement, which now stands at 7.2 liters. This larger displacement allows for a broader range of torque options, ensuring greater flexibility across various applications and duty cycles.
Our customers have used the B-Series engine for more than 40 years and rely on it every day to meet their needs,” said Jose Samperio, Vice President – North America On-Highway. “It was important that we offer the reliability and performance that they have come to expect, while also creating an engine that is built to last for the future.
The B7.2 engine will deliver improved top-end performance, offering power ratings ranging from 240 to 340 horsepower and torque output between 650 and 1,000 lb.-ft. This increased power range ensures that the engine can handle a wide variety of demanding operational needs.
Advanced Efficiency and Environmental Benefits
Cummins has integrated several advanced features into the B7.2 diesel engine to enhance efficiency and reduce emissions. The engine is designed to be stop-start capable, helping to lower greenhouse gas emissions by automatically shutting down during idle periods and restarting as needed. This feature can significantly reduce fuel consumption and operating costs.
Additionally, the B7.2 will come equipped with an automatic engine shutdown function, further promoting fuel efficiency and environmental sustainability. These enhancements align with Cummins’ ongoing efforts to create more environmentally friendly power solutions.
Another notable feature is the compression release engine brake, which contributes to improved safety and reduced wear on braking components. The extended oil drain interval pan option will further enhance operational efficiency by reducing maintenance frequency and costs.
Digital Connectivity and Smart Technology
Cummins has equipped the B7.2 diesel engine with its full suite of digital technologies, aimed at maximizing uptime and reducing the total cost of ownership. These technologies provide immediate access to various applications and capabilities through Acumen®, Cummins’ smart computing hardware, and OEM first-fit solutions.
Customers can take advantage of predictive maintenance tools, including Cummins Maintenance Monitor, which reduces the need for frequent shop visits and helps minimize the overall cost of operation. The integration of advanced over-the-air updates ensures that vehicles remain up to date with the latest performance and efficiency enhancements without requiring downtime for manual updates.
Manufacturing and Production Timeline
The B7.2 diesel engine will be manufactured at the Rocky Mount Engine Plant in North Carolina. Production is scheduled to commence in North America starting in 2027, marking a new era for the B-Series engine lineup.
The unveiling of the B7.2 diesel engine at NTEA Work Truck Week provides industry professionals with an opportunity to learn more about its capabilities and benefits.
