MAN Nutzfahrzeuge at the Busworld Kortrijk 2009

At the European bus industry's premier fair, the Busworld in Kortrijk (October 16 - 21, 2009), MAN Nutzfahrzeuge has been presenting a wide range of MAN and NEOPLAN coaches, city and intercity buses. In Hall 2, at Stand 204A and 204B , a 290-hp MAN Lion's City LEU, a 360-hp MAN Lion's Regio C and a 440-hp MAN Lion's Coach L has been on display. The NEOPLAN brand is be fittingly represented by a Starliner L as well as a Cityliner C in the Individual version. In addition, a 480-hp Cityliner C Coach with MAN TipMatic has been on hand in Kortrijk for test drives.

The spotlight is on the current bus engines, which conform to the EEV standard  thanks to MAN PURE DIESEL technology. The range extends from the vertical  D08 common-rail engine of the 290-hp MAN Lion's City LE to the 505-hp D26 CR, which right now is the most powerful coach engine and is exclusively available for the NEOPLAN Starliner.

In all classes, MAN Nutzfahrzeuge has skipped the Euro 5 standard and moved directly to the voluntary, even more stringent EEV standard (Enhanced Environmentally friendly Vehicle) for its extremely efficient common-rail engines. These engines remain below the exhaust gas limits set in the Euro 5 standard, in force from October 2009, without requiring additional operating fluids.

Innovative technologies have been employed in order to reach this challenging goal without compromising reliability and efficiency. These include exhaust-gas recirculation (EGR), optimised once again compared to Euro 4, with a new kind of control by lambda probe, and low-temperature cooling of the charge air. With the aid of the third generation common-rail injection system, finely atomized fuel is pressed into the cylinder at a pressure of up to 1,800 bar.

Thanks to innovative two-stage charging, raw particulate emissions have been reduced to such an extent that the D20 LOH and D26 LOH coach engines conform to the EEV standard when equipped only with the patented MAN PM-KAT. 

This is entirely service-free, and exhibits an especially high deposition rate for very fine particulates, making it particularly suitable for use in buses with routes in densely populated areas. MAN's new bus engines meet the statutory requirements and the voluntary standards without the use of additives and thus without the typical disadvantages of SCR such as loss of space and reduced payload - and this with optimum consumption values, as various tests in leading trade magazines have demonstrated over the past few months.
