Executive Summary

Due to stringent exhaust emissions legislation there is continuous pressure on owners of commercial off road diesel driven vehicles and machinery, also known as Non Road Mobile Machinery (NRMM), to replace or upgrade their equipment or invest in new ways to reduce the pollutant emissions from combustion engines installed in NRMM, which in turn reduces their carbon footprint.

Engine emissions standards for NRMM are set by the European Union under Regulation (EU) 2016/1628 of the European Parliament, which sets the requirements relating to gaseous and particulate pollutant emission limits and type approval for internal combustion engines. Internal combustion engines installed in NRMM significantly contribute to air pollution by emitting carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), nitrous oxide compounds (NOx) and particulate matter (PM).

The NRMM EU Regulation defines emission limits for engines with different power ratings and applications. It also stipulates the procedure that engine manufacturers must follow in order to obtain type approval for their engines.
This report studies three pieces of NRMM heavy plant used by a port operating company. Emissions and fuel consumption readings were recorded over a three month period before and after the addition of the fuel additive, AquasolveTM. The plant was tested in workshop conditions and the data gathered for analysis.
The results demonstrate a significant reduction in emissions and fuel consumption when the additive is used. The figures derived from the emissions reductions and cost benefit analysis also demonstrate the potential savings if the plant was operating at the conservative figure of 500 operating hours annually using the additive.
