STAGE V DIESEL ENGINES – TURF EQUIPMENT

STAGE V Regulation (EU) 2016/1628 – Non-Road Mobile Equipment Application

The European emissions standards, commonly referred to as "EU Stage V", will apply to engines installed in off-road mobile equipment, as stipulated according to engine output. These EU Stage V tandards will also be applicable to diesel engines with an output range of less than 19 kW, which were reviously not targeted by the existing standards. For models with an output of 19 kW and more, the permitted values for NOx and PM (Particulate Matter) emissions are one level stricter than previous standards. In addition, new PN (Particle Number) standards have also been set making the new emissions standards generally the strictest in the world.

With this regulation in place, all diesel powered turf equipment is impacted!

Why are PM and NOx critical components?

	PM	NOx
ALSO KNOWN AS	PM Particulate Matter, airborne particles such as soot, smoke	NOx Nitrogen Oxide (NO), Nitrogen Dioxide (NO2)
WHAT IS IT?	PM Unburned Hydrocarbons (fuel)	NOx Molecule that is created in the combustion process
WHAT CAUSES IT?	PM Low combustion temperature Low oxygen level during combustion Low combustion pressure	NOx High combustion temperature High oxygen level during combustion High combustion pressure
WHY IS IT A REGULATED EMISSION?	PM Soot particles are very small and get trapped in the lungs Associated as a cause of cancer	NOx NOx molecules attach to other elements in the atmosphere and produces smog

Also regulated in engine above 19 kW
PN – Particle Number. Regulates the number of particulates contained within a mass unit of emissions; separate from the existing PM

For John Deere turf equipment there are two power categories, that require different engine technology:

Engine technology – The technical challenge

This trade-off requires modern engine technology and, above 19 kW, after-treatment devices.

To reduce PM, it needs:

increase in oxygen level
high combustion temperature
increased combustion pressure
advanced engine timing

To reduce NOx, it needs:

lower oxygen level
lower combustion temperature
lower combustion pressure
retard engine timing

Regulations for diesel engines in the turf range

Regulation diversify by power category

ENGINE POWER – kW	0 < P < 8	8 ≤ P < 19	19 ≤ P < 37	37 ≤ P < 56
ENGINE POWER – hp	< 10.7	10.7 ≤ P < 25.5	25.5 ≤ P < 50	50 ≤ P < 75.1
CO – g/kWh (g/hph)	8.00 (6.00)	6.60 (4.90)	5.00 (3.70)	5.00 (3.70)
NMHC+NOx – g/kWh (g/hph)	≤ 7.50 (5.60)	≤ 7.50 (5.60)	≤ 4.70 (3.50)	≤ 4.70 (3.50)
PM – g/kWh (g/hph)	0.40 (0.30)	0.40 (0.30)	0.015 (0.011)	0.015 (0.011)
PN – #/kWh			1×10¹²	1×10¹²
