GreenPower Green Power

GreenPower engines, what does it mean and what is so special about them?
The GreenPower system consists of a durable and reliable diesel engine with the corresponding exhaust after-treatment system.

The aftertreatment system consists of the following main components:

Soot Filtration / Oxidation:
By applying a DPF / SCR combination, the engine meets the EU Stage V emission requirements. The GreenPower system works on the basis of passive regeneration, which means that there is no diesel burner mounted in the exhaust so the system does not consume unnecessary fuel. Passive regeneration takes place through the application of a so-called Diesel Oxidation Catalyst (DOC), this DOC is mounted directly after the combustion engine in the exhaust pipe.

The DOC is a catalyst aimed at reducing emissions of harmful CO (carbon monoxide) and hydrocarbons. The DOC uses a honeycomb structure as a contact surface between the exhaust gases and the metals of the catalyst, in this the hydrocarbons (HC) and carbon monoxide (CO) are broken down. Also, nitrogen monoxide (NO) is converted to nitrogen dioxide (NO²), through this conversion it is possible to passively regenerate the particulate filter. The remaining soot particles are trapped in the deep filter pores of the DPF filter, so they do not end up in outside air but remain in the filter. To prevent the filter from filling up and thus increasing exhaust back pressure, (increasing back pressure is reduction in engine performance) the DPF filter must regenerate.
By applying the DOC, the NO particles present in the exhaust gases are converted to NO², because of this conversion, soot can already oxidize at a low temperature so that the DPF filters do not fill up and thus the back pressure does not increase too much.

NOx reduction

SCR or selective catalytic reduction is a catalyst aimed at removing the NOx (Nitrogen Oxide) from the exhaust, to achieve this, urea is injected into the exhaust. The injection of urea is done “airless”, which means that the system does not need an additional air compressor, thus resulting in low urea consumption. After injection the urea mixes with the exhaust gases. Inside the EATS housing are the SCR elements, where the chemical reaction takes place that converts >95% of the nitrogen oxide (NOx) to water (H2O) and nitrogen (N2).

Compact system

By placing the DPF filters and SCR elements in EATS housing, the system is much more compact than systems where DPF and SCR are in separate housings.
