EU Stage V is the latest stage of engine emission legislation designed to reduce pollution from off-highway machines, affecting European territories only. In order to meet these guidelines, Autostop and DPF has been introduced across all applicable models. 

Autostop

Auto Stop helps reduce fuel consumption by automatically shutting down the machine when not in-use as well as prevents excessive idle times which reduces machine clock hours. It is operator configurable using the easy to use intuitive interface, allowing working patterns to be taken into consideration.

DPF 

All Stage V machines above 19kW now have to have a Diesel Particulate Filter (DPF) as part of the after treatment system. The introduction allows emissions legislations to be met. All manufacturers have had to adopt this.

The key changes for Stage V are reductions in particulate mass by approximately 40% and the introduction of particulate count.
 
Stage V is the sixth in a series of legislative stages which began in 1996, to reduce the following pollutants:

- NOx: Nitrogen Oxides

- PM: Particulate Matter

- CO: Carbon Monoxide

- HC: Hydrocarbons

 

ASC - Removes any ammonia present in the exhaust gases.
DEF – Diesel Exhaust Fluid. Sometimes referred to as Ad-Blue. Used in conjunction with SCR to convert excess NOx emissions into nitrogen gas and water vapour. 
DOC – Diesel Oxidation Catalyst. Oxidised hydrocarbons and carbon monoxide emissions, transforming them into water and carbon dioxide. This works automatically, requiring no regeneration. 
DPF – Diesel Particulate Filter. Used to capture excess particulate matter which over time will clog the filter and require regeneration. Regeneration is a self-cleaning process via the use of high temperatures to burn of captured particulate matter. 
Automatic regeneration – DPF regeneration occurs automatically, no action is required by the operator and the machine can be used as normal. If exhaust temperature reaches a certain limit during an automatic regen then the High Exhaust System Temperature (HEST) lamp may illuminate. The operator needs to be aware of the increased exhaust temperatures, as they can be hazardous in a flammable environment, and may cause harm/damage to nearby objects and personnel.
Manual regeneration –  Operator initiated DPF regeneration. The machine cannot be used for normal work whilst regeneration is taking place and it should be parked in a safe environment. The HEST Lamp may illuminate during this process.
SCR – Used in conjunction with DEF to convert excess NOx emissions into nitrogen gas and water vapour
NOx – Gases that are produced during combustion, they are a combination of Nitrogen and Oxygen.
SCRF – A combination of a selective reduction catalyst and a Diesel particulate filter into one element
ULEZ – Ultra Low Emission Zones
