More With Less.

The inline 4-cylinder B4.5 delivers 16 percent more power and 11 percent more torque than the current version of this engine. The Cummins-designed wastegate turbo is a key component in delivering exceptional power and responsiveness for faster cycle times

Not only do you get more power – you use less fuel, with total fluid efficiency (included both fuel and Diesel Exhaust Fluid) improved by up to 3 percent. Equipment used in duty cycles with frequently idling can improve fuel economy even more with Cummins Stop-Start technology.

EGR-free architecture reduces complexity, improves reliability and reduces the cooling system space claim. Multiple component options allow for easier installation and maintenance. These include a choice of front- or rear-sump oil pan locations, on-engine or remote-mounted options for ECM and maintenance filters, the option of Rear Engine or Front Engine Power Take Offs, plus your choice of three turbocharger orientations; high-mount rear, front-out or mid-mount.

The Single Module™ aftertreatment system combines DPF, SCR and urea dosing in one unit which takes up 50 percent less space and weighs 30 percent less than the prior system.

B4.5 owners will also benefit from Cummins Connected Diagnostics™, remote monitoring technology that wirelessly connects the user’s engine to Cummins experts for instant analysis and recommended action the moment a fault code is generated on any piece of equipment equipped with a telematics.

The B4.5 is also available with Cummins Guidanz™ technology, which provides a seamless, process-guided package that streamlines the diagnosis and repair process, ensuring that the right parts, tools and support can be brought onsite to speed up repairs.

High sulfur tolerance allows OEMs to install the B4.5 in equipment working in areas with limited fuel quality capability.

Cummins B4.5 for 2019 delivers more machine capability and more uptime as it lowers the Total Cost of Ownership (TCO) – so equipment users can do more with less.
