Mack Adds Air Disc Brakes to Vocational Truck Lineup

Jan. 28, 2014

LAS VEGAS (Jan. 21, 2014) – Work truck customers looking for superior stopping performance in harsh conditions and duty cycles can now order Meritor EX+ Air Disc Brakes for their MACK® Granite®, TerraPro™ and Titan by Mack models. Mack introduced the air disc brakes offering across its vocational lineup today at the 2014 World of Concrete exhibition.

“Mack’s air disc brakes are built to our standards and tuned specifically for the needs of vocational customers to help boost uptime and lower overall lifecycle costs,” said Stu Russoli, Mack vocational marketing product manager. “Vehicle operators and workers on the job site can also enjoy the added safety benefits of the air disc brakes’ exceptional stopping performance.”

More than 2.2 million miles of real-world service in North America has shown that the air disc brakes deliver superior stopping performance and require less maintenance than conventional S-cam designs. Mack’s air disc brakes utilize a flat rotor concept to prevent heat distortion in heavy-duty service, rather than “hat-shaped” rotors, which are prone to distortion and shorter life. The brake pads are engineered by Mack to deliver top performance in all situations and minimize brake fade during extreme braking cycles and frequent use.

“In line with our philosophy of application excellence, our air disc brakes are optimized to give customers a durable option for excellent performance in any type of work environment,” said John Walsh, Mack vice president of marketing.

Mack began offering air disc brakes in 2008 on its MACK® Pinnacle™ Axle Forward and Axle Back models.

CAPTION: Mack’s air disc brakes (left: drive axle, right: steer axle) are now available for MACK® Granite®, TerraPro™ and Titan by Mack models.

Rolling Meadows, IL, January 20, 2014- Komatsu America Corp. is pleased to announce the introduction of its new EPA certified Tier 4 Final diesel engines, built on Komatsu’s progressive engineering improvements to reduce emissions. In addition, most machines will see reductions in fuel consumption below the already low levels that have long been a hallmark of the Komatsu product line. The Tier 4 Final technology will be integrated into Komatsu America’s construction and mining engines ranging in size from 3.3 to 46 liters and start commercial production in January 2014.

New regulations effective in 2014 require the reduction of NOx emissions to one tenth or below levels required by preceding regulations. Komatsu’s Tier 4 Final solution builds on the proven and reliable Komatsu technologies utilized for Tier 4 Interim engines. Examples of these Komatsu-developed technologies include: next-generation high-pressure common rail fuel injection (HPCR) system; high-efficiency exhaust gas recirculation (EGR) system; Komatsu Variable Geometry Turbocharger (KVGT); and Komatsu Diesel Particulate Filter (KDPF).

These Komatsu Tier 4 Interim technologies have been well received by customers in North America. In addition to refining these technologies through Komatsu’s continuous improvement activities, Komatsu has also developed a newly designed proprietary Selective Catalytic Reduction (SCR) device. This Tier 4 Final solution with the addition of SCR provides a high amount of passive regeneration of the KPDF with minimal impact on machine operation and production.

All Komatsu Tier 4 Final construction machines come with Komatsu CARE®. Komatsu CARE® provides scheduled factory maintenance for the first 2,000 hours or three years, which includes a 50 point inspection at each service, and two complimentary KDPF exchanges in the first five years.

Over the years Komatsu has consistently engaged in the research, development, manufacture and improvement of diesel engines. Komatsu will continue to leverage in-house development and manufacturing capabilities for key components, such as hydraulic devices and control systems, in order to reduce environmental impact and improve fuel economy.

New engine is designed to meet EPA Tier 4 Final emissions regulations in North America.

Technologies Applied to the New Engines

1. Heavy-Duty Aftertreatment System

This new system combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR). The SCR NOx reduction system injects the correct amount of AdBlue®/DEF at the proper rate, thereby decomposing NOx into non-toxic water (H2O) and nitrogen gas (N2).

With the addition of the SCR system, a stringent design target of “fluid neutral” or better was established. In a “fluid neutral” situation, the volume of fuel burned plus the volume of AdBlue®/DEF consumed is equal to or less than the total volume of fuel burned in the previous generation machine. This achievement lowers operating costs for the end customer as AdBlue®/DEF typically costs less than diesel in North America.

To ensure product reliability and durability in demanding conditions, Komatsu developed the entire system, including the control software which is critical to the effective operation of the aftertreatment system. This control system is also integrated into the machine’s on-board diagnostics systems and KOMTRAX®, Komatsu’s standard telematics system, which constantly monitors the machine’s health.

2. Heavy-Duty Cooled Exhaust Gas Recirculation (EGR) System

The system recirculates a portion of exhaust gas into the air intake and lowers combustion temperatures to reduce NOx emissions. Incorporating a high-efficiency and compactly designed cooling system, increases EGR gas flow, which reduces NOx and helps reduce fuel consumption as an additional benefit.

3. Advanced Electronic Control System

To ensure control of equipment in all conditions, the electronic control system performs high-speed processing from sensors installed in the vehicle and engine. While maintaining the powerful and quick response of Komatsu equipment, the precise system helps greatly reduce NOx and particulate matter emissions while improving fuel consumption and noise.

The machine operator is informed of engine conditions via the on-board color monitor inside the cab. Using KOMTRAX®, Komatsu’s machine health telematics system, to manage the information keeps customers apprised and informed of appropriate operational factors and required maintenance.

4. Komatsu Variable Geometry Turbocharger (KVGT) System

The KVGT system features Komatsu-original hydraulic technology for variable control of intake air-flow and supplies proper amounts of air according to load conditions. The machine’s control system uses the KVGT to provide precise exhaust temperature management for the regeneration process. The system achieves high efficiency combustion, further purification of exhaust gas and improved fuel economy.

5. Heavy-Duty High-Pressure Common Rail (HPCR) Fuel Injection System

Utilizing computerized control, the system is designed for proper injection of high-pressure fuel. Building on the technology in previous Komatsu engines, the new system uses higher-pressure injection for better fuel atomization, reducing both Particulate Matter (PM) emissions and fuel consumption under the wide range of engine-operating conditions.
