Today, engine development is determined by tightening emission standards globally. Therefore any additional systems, which are capable of reducing critical emissions, are now highly sought after and must be, integrated into overall engine design concepts in order for companies to meet and even out perform government emissions guidelines.

Air2Nitrous™ is an essential external optimization device designed as an engine retrofit concept. Its effect on an engine’s overall performance singularly outweighs just about any other part. This is because the technology has a direct bearing on critical emissions reduction, economy and engine dynamics.


Air2Nitrous™ was designed and specifically configured to satisfy the high demands of engines performance across a broad range of operating speeds, dynamic response, fuel efficiency, economic performance, reduction of critical emissions, delivery of turbo-charging like affects and service life.

Air2Nitrous™ was created with the concept of a compact design with minimal dimensional requirements to benefit customers and allow for ease of retrofitting and repowering engines.

As an upstream (prior to and during combustion) retrofit device Air2Nitrous™ can be classified as a ‘first phase’ emissions control technology, whereby most of the harmful emissions are removed before encountering subsequent emissions technologies. Systems such as turbocharging, common rail fuel injection, intercoolers and charge-air coolers would be considered midstream or ‘second phase’ emissions control technology with downstream (after exhaust) systems such as selective catalytic reduction (SCR), exhaust gas recirculation (EGR) with exhaust aftertreatment, diesel particulate filter (DPF) and diesel oxidation catalyst (DOC) can be classified as ‘third phase’ emissions control technology.

A common feature of emissions reducing technologies i.e., EGR, SCR, DPF’s, and DOC’s is they all have a tendency to negatively affect engine performance and responsiveness in one way or another (see ‘PM/NOx trade-off theory’ and ‘three-way interaction’ further down in the document), which Air2Nitrous™ technology can to a large extent singularly alleviate.
