This Technology also provides the opportunity to utilise a quick responding Turbo charger in combination with a bypass function, providing quick drive away characteristics corresponding to engines with larger displacement.

EXHAUST-GAS RECIRCULATION (EGR) The Euro 3 guidelines require a reduction in nitrogen oxides (Nox) in the exhaust gas to less than 5g/kWh. The technical measures to adhere to this value lead to higher fuel consumption. To minimise the increased consumption, MAN Euro 3 engines have been equipped with a cooled exhaust-gas recirculation, EGR, since the TG-A was introduced. With EGR, part of the exhaust gas is added to the air volume taken in to further reduce the combustion temperature. This measure increases the specific heat of the intake air and reduces the oxygen content. With the current state of the art, the engine modifications for pollutant reduction in conjunction with externally cooled exhaust-

TECHNOLOGY FOR EURO 4 MAN PM CATALYTIC CONVERTER SYSTEM The solution to achieve Euro 4 requirements include the introduction of the MAN PM Catalytic Converter System. This involves the reduction in nitrogen oxide values by means of externally cooled exhaust-gas recirculation in conjunction with exhaust-gas aftertreatment for reduction of particle emissions (MAN PM Catalytic Converter System). The advantages of this technology are low weight, low costs and no recourse to additional use of space on the chassis. The PM Catalytic Converter System is a MAN in-house enhancement of the CRT filter system. The designation “PM-Kat”

is a registered trade mark, protected for MAN. In comparison with the CRT filter system, the soot particle separator section of the MAN PM catalytic converter is configured as an open, nonclogging system. The PM Catalytic Converter System requires no additional fitting space beyond the existing dimension of the muffler. It will be used at MAN together with the cooled exhaustgas recirculation as a technical solution to achieve the Euro 4 requirements. Function schema of the MAN PM catalytic converter.
