Recently, the Auman EST Super Truck, equipped with the powerful Cummins X12 engine, has won over drivers with its strength and performance. Designed as the exclusive engine for super trucks, the Cummins X12 boasts outstanding power and quality, making it the perfect partner for the Auman EST. Today, let’s take a closer look at this impressive engine and uncover the secrets behind its capabilities.

Smart Technology

The Cummins X12 engine integrates three key smart technologies: ADEPT Smart Driving Assistance, PowerSpec Intelligent Vehicle Management, and Connected Diagnostics for remote services. Together, these features allow the engine to dynamically manage powertrain torque output and enable coast mode, balancing fuel efficiency with power. This intelligent setup provides users with an optimal power configuration while real-time engine data is used to deliver solutions for peak performance.

As the exclusive engine for super trucks, the Cummins X12 brings practical, smart solutions that enhance drivers' experience on the road.

Efficiency

The X12 leads its class in power density for engines in the 10-15L range, boasting high torque at low speeds. It delivers up to 2,300 Nm at just 1,000 RPM, maintaining maximum torque between 1,000 and 1,400 RPM. This means easy acceleration, overtaking, and climbing. It’s also equipped with a second-generation iBrake engine braking system that offers 400 horsepower of braking force, reducing wear on the primary brakes, lowering costs, improving speed control, and enhancing safety.

With the Cummins X12, the Auman EST Super Truck delivers both power and peace of mind, ensuring a safe ride with substantial horsepower.

Fuel Efficiency

The X12’s XPI ultra-high pressure fuel injection system operates at up to 2,000 bar, optimizing fuel atomization. Leak-free pressure retention ensures precise fuel control and complete combustion, increasing fuel efficiency. Improvements in friction components enhance fuel economy, while the compact and efficient exhaust after-treatment system reduces heat management demands, further lowering fuel consumption. These features help users save on fuel costs on every journey.

Quality

The Cummins X12 engine is built for durability. Key components are reinforced with high-quality materials, and the integrated steel piston design enhances longevity. New diamond-like coating technology for the piston pin and oil ring reduces oil consumption, improving system adaptability and endurance. Its integrated dustproof design prevents dust intrusion, while Cummins’ patented ISOPOD turbocharging technology enables operation in harsh conditions, significantly boosting reliability.
