The numbers are significant, with its creator global engine tech developer Air2Nitrous (A2N) claiming the device (by the same name) achieves up to 90% reduction in critical engine emissions, up to 20% fuel savings and up to 17% more engine torque and horsepower immediately after install.

“Air2Nitrous has achieved what many of the world's largest emissions technologies companies have been trying to do for years – a reduction in critical emissions plus savings on fuel without sacrificing vehicle performance,” Air2Nitrous CEO Ed Nichols said.

“All the while Air2Nitrous accomplishes this using a retrofit device comprised of only two components and no moving parts.”

The simple device is a first phase electronic emissions control system, whereby most of the harmful emissions are removed before encountering subsequent emissions technologies, and can be fitted by any qualified mechanic to any internal combustion engine in 30 minutes.

A2N works by increasing the amount of oxygen molecules and decreasing the amount of nitrogen molecules present in the combustion chamber.

More oxygen in the combustion chamber means a more complete burn of particulate matter 2.5 and less nitrogen means less mono nitrogen output. The net effect is reduced critical emissions of carbon monoxide (CO), carbon dioxide (CO2), mono nitrogen (NOx), total hydrocarbons (THC), particulate matter (PM) 2.5, non-methane organic gas (NMOG) and non-methane hydrocarbons (NMHC) up to 90%. A2N technology also helps to expel increased levels of oxygen in the process.

The technology is suited to mining applications, long haul transport, off-road vehicles, diesel trains, generators and coal-fired power stations among others.

A2N has already passed Californian emissions standards on vehicles with and without catalytic converters and was tested on a Nissan Maxima 2002 in Australia, where it demonstrated a 60% reduction in CO,9.3% in CO2, 89.9% in HC, 75% in NO2 and 9.3% of fuel savings.

A2N is available globally.
