Key technologies from MAN – maximum economy, minimum environmental impact
Consistent reduction of environmentally harmful emissions demands top level technical expertise – MAN can provide solutions tried-and-tested over many years. MAN Truck & Bus ensures dependable compliance with the Euro 6 exhaust gas limits with its elements Common Rail, Exhaust-Gas Recirculation (EGR), Selective Catalytic Reduction (SCR) and Diesel Particle Filters (DPF/ CRT).
MAN was the first manufacturer to use the Common Rail System in all its engine series – and this was as early as in 2004. This system forms the basis for current and future compliance with the exhaust-gas standards for all MAN engines. Common-Rail engines stand out primarily due to their smooth running, low noise and pollutant emissions, as well as optimum control of the injection process and the potential fuel reduction this brings about.
Exhaust-Gas Recirculation (EGR)
The exhaust-gas recirculation (EGR) in conjunction with cooling of the return gases provides for a lower temperature in the cylinder combustion chamber – therefore fewer nitrogen oxides are produced during combustion.
SCR – MAN AdBlue®
MAN AdBlue® technology with SCR (= Selective Catalytic Reduction) reduces emissions of nitrogen oxides (NOx) by approximately 90 percent. AdBlue® is used here, a synthetically manufactured 32.5 % urea solution.
CRT filter ( DPF)
The MAN CRTec® System (=Continuously Regenerating Trap, electronically controlled), called a Diesel Particle Filter (DPF) in German, is also used to meet the high Euro 6 requirements for particle values. Up to 99 % of particles are filtered out of the exhaust gas.
