Now more than ever, our research and development activities focus on our products’ environmental compatibility. While we do this, we concentrate especially on resolving these two questions:

1. How can engines’ specific fuel consumption be reduced further?
2. How can harmful emissions, which are an unavoidable consequence of burning fossil fuels, be reduced to a minimum?

This task is an extremely challenging one, since improvements in one of these areas can only be achieved at the expense of the other. Fuel savings and thus a reduction in CO2 during combustion, for instance, can often only be “traded off” for higher nitric oxide emissions. Less consumption doesn’t always mean fewer emissions. MAN Diesel & Turbo is therefore pursuing a holistic philosophy: our engines and systems are very economical while having low emissions values. To achieve this, our development engineers have been working on innovative solutions for many years. As a result, we are able to offer our customers sophisticated environmental technologies that are classified into primary and secondary measures.

Just how high the harmful emissions ultimately are depends not least on the fuel being used. In principle, our diesel engines can be operated with all manner of fuels. As well as heavy fuel oil, these include for instance marine diesel oil, natural gas or bio-fuels. Depending on which fuel is used, different levels of emissions are produced. Environmental technologies from MAN Diesel & Turbo, however, ensure that these emissions are always kept as low as possible.
