ENGINE of the articulated truck
Optimized Performance, Proven Reliability
ENGINE TECHNOLOGY
The engine continues the evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components with proven reliability.
CLEAN EMISSIONS MODULE (CEM)
The CEM is an exhaust after-treatment 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.
NOX REDUCTION SYSTEM (NRS)
The 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 of the articulated truck
The engine utilizes the common rail, high-pressure, electronic metering system to the injectors.
DIESEL PARTICULATE FILTER REGENERATION
Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The After-treatment Regeneration Device (ARD) utilizes the Regeneration System 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.
