    Engine

    Optimized Performance, Proven Reliability

    Engine Technology

    The Cat® C13 ACERT engine continues the evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability.

    Cat Clean Emissions Module (CEM)

    The Cat CEM is an exhaust aftertreatment package consisting of a Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR)catalyst, using a urea water solution (UWS), known as Diesel Exhaust Fluid (DEF), and control systems. The CEM reduces both particulate and NOx emission using passive and active regeneration, dosing, burner and dosing/burner combinations during normal engine operation. All components are isolation mounted on a rigid supporting cradle for long service life in the most severe applications.

    Cat NOx Reduction System (NRS)

    The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

    Fuel Delivery

    Mechanically actuated Electronic Unit Injection (MEUI-C) multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.

    Diesel Particulate Filter Regeneration

    Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The Aftertreatment Regeneration Device (ARD) utilizes the Cat Regeneration System (CRS) to efficiently and automatically regenerate the DPF. The DPF traps both particulates and ash; the ash is removed at regular service intervals.

    Modes of Regeneration

    When set to automatic, regeneration will occur without any interaction from the operator. The three modes of regeneration shown below allow the articulated truck to adapt to specific site conditions in the most efficient manner. Automatic: “On-the-go” regeneration is initiated when the engine control module determines conditions are acceptable. The articulated truck is not required to stop working. Automatic: Low idle regeneration is initiated when the machine is in a reduced operating mode for a predetermined period of time, and a number of conditions are met. The system is designed so that the operator can interrupt regeneration at any time. Manual: A manual regeneration is initiated by pressing the regeneration switch for five seconds. The machine must be brought to a non-operating mode in order to perform a manual regeneration.

    Engine Compression Brake

    The Cat C13 ACERT engine compression brake improves retarding response and increases retarding power.

    Transmission

    Class Leading Transmission Technology

    Electronic Transmission

    The Cat CX31 six-speed forward one-speed reverse Electronic Clutch Pressure Controlled (ECPC) transmission featuring Advanced Productivity Electronics Control Strategy (APECS) delivers smooth shifting with strong acceleration and high productivity. The Cat C13 ACERT engine coupled with the CX31 transmission deliver increased forward and reverses rimpull. Featuring:

    • A speed hold/limiting function allows the machine speed to be limited in one km/h or one mph steps to conform to site speed restrictions.
    • Critical gearshifts maintain direct drive lock-up, and eliminate dropping into converter drive. This maintains ground speed during shifts on grades.
    • The transmission automatically modifies shift points to best suit operating conditions.
    • Retarding levels are automatically reduced on lesser grades in lower gears.

    Torque Converter

    A large diameter torque converter, configured for off highway applications, allows the engine power to be transmitted more efficiently to the lower power train.

    Automatic Traction Control (ATC)

    The Most Advanced Traction Control System

    Automatic Traction Control (ATC)

    Fully Automatic Traction Control (ATC), with Inter-Axle-Differential lock (IAD) and Cross-Axle-Differential locks (XAD) feature oil immersed clutches that require no operator input. Operation is seamless and smooth, eliminating wheel slip for maximum traction. Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions. Fully automatic, independent, IAD and XAD clutches are engaged on-the-go to optimize machine performance and control in all conditions. Clutches are automatically disengaged when ground conditions dictate, maximizing efficiency when steering or on uneven ground. Clutches are engaged proportionally, from 0% to 100%, as ground conditions dictate. ATC eliminates wheel spin in soft underfoot ground conditions or on slippery grades. It also reduces tire and driveline abuse caused by improper manual operation of the differential clutches. The ATC allows ‘true’ 6×6 drive with proportionally open differentials for best power efficiency.
