The best of all worlds

Cummins is the undisputed global leader in high-performance diesel engines in on highway applications. For nearly two decades, the Cummins X Series platform has continually set new standards for power, productivity, low cost of operation and total value.

The new lightweight, high-output 12-litre X12 meets Euro VI standards. With impressive peak outputs of 490 hp and 1696 lb ft of torque, the X12 has the highest power-to-weight ratio of any engine in the 10-to-16-litre class. The innovative architecture of the X12 results in a remarkably low engine weight of 917 kg, achieved through a sculptured block design and the use of high-strength composite materials.

The X12 is Euro VI emissions compliant using selective catalytic reduction (SCR) technology with AdBlue®/DEF (Diesel Exhaust Fluid) dosing.

The use of a rear geartrain also contributes to overall engine refinement by reducing vibration and lowering noise. The X12 uses a standard wastegate turbocharger and also has an integrated engine brake that delivers the high retarding power that Cummins heavy-duty engines are renowned for. The engine’s single cam in-head design with roller valve train and high efficiency intake ports continues the design theme of minimum complexity and maximum efficiency.

Features & Benefits

Stronger power and torque for improved productivity and driveability:

• Up to 490 hp (483 kW) with a peak torque of 2,400 Nm (1,696lb-ft) available as low as 1,100 RPM
• Optimised power curve improves driver satisfaction requiring less gear changes, enabling low engine speed operation for improved fuel efficiency
• Excellent low speed torque enables fast acceleration and exceptional
• gradient climbing
• EGR-free design meeting Euro VI emission standards

Higher efficiency to reduce operational costs:

• Single cam in head design with roller valve train and high-efficiency intake ports minimises complexity and maximises efficiency
• Programmable features like load based speed control and gear down protection serve to maximise fuel efficiency
• Patented cooling system, lube system and power cylinder are designed for improved efficiency
• Optimised combustion system and electronic calibrations enable heavy-duty performance without excessive injection pressure

Advanced architecture ensures proven reliability:

• Sculptured block retains high rigidity while removing unnecessary mass
• Modular component architecture significantly reduces the number of parts
• Cummins XPI fuel system along with an optimised combustion system provide excellent cold start performance in extreme temperatures and high altitude
• Stiffer design through advanced component design and production techniques

Extended maintenance intervals and easy serviceability lowers cost of ownership: 

• Patented Fleetguard Stratapore oil filters that reach up to 100,000 km
• NanoNet™ fuel filtration provided unmatched protection for the engine’s fuel system, removing particles as small as four microns
• Integrated design uses replaceable wet liners, enabling multiple overhauls
