Dual-fuel engine reduces nitrogen dioxide and soot emissions

The need to reduce nitrogen dioxide emissions is not solely aimed at the automobile industry, but also includes the aerospace and maritime industry. To this end, an Italian engineer has developed a dual-fuel system that significantly reduces exhaust pollutants and also reduces maintenance costs.
Dual-fuel engine reduces nitrogen dioxide and soot emissions
Aimed at medium-sized marine diesel engines of 500 - 6,000 KWs, the dual-fuel system incorporates innovative catalyst-based adaptors that can combust the two different types of fuel. The primary fuel is diesel, whilst the secondary fuel is a derivative of methanol; and the engines actually burn the two fuels simultaneously with a 50/50 mix ratio.

Using new technology that converts methanol to methane, the catalyst-based adaptor mixes water with the methanol, which in turn feeds the resultant methane gas and diesel into the engine. The exhaust pollutants result in a low soot output whilst the nitrogen dioxide gas is transformed into harmless nitrogen.

Because of the unique methanol to methane conversion, the inventive engineer is prepared to offer his services and training to any third party who maybe interested in incorporating this device. This is because the existing prototype can be modified and configured around any clients existing engine specifications or installed directly into new engines.

It is also worth noting that the benefits derived from the reduced pollutant emissions and maintenance costs are not limited to marine engines. The medium sized dual-fuel engines can also be applied to other heavy engineering manufacturers such as railways, roadwork, agriculture or even the construction industry.
