Solution to make diesel engines compliant with the emission regulation

Solution to make diesel engines compliant with the emission regulation

Eneria is a specialist in turnkey projects with engine systems and power plants and Caterpillar’s exclusive dealer in France. With the new emission rules, they have developed a solution which can reduce Nox from diesel engines so as to be compliant with the actual market demand. The solution is called Neaux Box. The principle of the Neaux box is to take advantage of the limit of the maximum moisture possible in the combustion air vs the relative humidity under the permanent control of the engine intake air dew point. The Eneria solution is to take benefit from the energy developed by the turbocharger with the aim of un-saturate the water mist introduced into the engine. During the combustion the part of the saturated vapour pressure of the air creates an endothermic reaction which helps to reduce the combustion temperature. This has a consequence to bring down the Nox. The Neaux Box continuously monitors the engine boost dew point and will compare with the intake manifold temperature in order to avoid any issue to the engine. This solution fulfils the emission regulation using diesel engines in order to be clean with the Nox and can be installed on any emergency plant like datacenters and hospitals.
