Ecological and efficient urban bus

The version of the new Man Lion's City Hybrid Bus series incorporates the system of high-performance Ultracap for the accumulation of energy, installed at the front of the vehicle in such a way that it does not harm the weight distribution and aerodynamics.

The technique of hybrid bus is based on the current model of low-floor urban bus Man Lion's City of construction Tower, as well as the current engine Common Rail EEV D08 (250 HP) with filter particles blind CRTec and electronic regulation. In the course of the year 2010, it will be operational a small number of these rigid vehicles in several European capitals that will be used as a bus line. Both Vienna, city in which the exhibition, such as Munich and the rest of the cities from 2010, which include Barcelona, will be the first cities in which these hybrid buses from Man to test mode will be used. Currently, the company is preparing a technical solution adapted to the demands of an articulated bus to introduced in series in 2012 and will be equipped with effective technology Ultracap.

Employment in the urban traffic offers ideal conditions to harness the energy of braking. Urban buses speed at the exit of each stop and slow down to get to the next until you stop it. To slow down, the conventional bus transform kinetic energy in heat untapped, while the Lion's City Hybrid takes advantage of the accumulated energy of braking to accelerate from the stop of organically and with a low level of noise.

About performed experiments prove that, depending on the profile of the use, it is possible to leave off the diesel engine for nearly 40% of the time of operation. With the Lion's City Hybrid, Man committed to a comprehensive package of measures resulting in a considerable saving of fuel between 25% and 30%. In addition, with an average mileage of 60,000 miles per year, hybrid bus Man avoids ten tons of greenhouse gas emissions.

For several years, natural gas of Man engines comply with the EEV standard (Enhanced Environmentally friendly Vehicle). Since the combustion process is developed with very low emissions, it is possible to do in this case without a complicated process of filtering with closed particulate filters.

As the engine of aspiration of Man E2866 DUH04 natural gas with 245 HP, which is no longer available for markets EU27 from the introduction of OBD2 (the ' diagnosis of a Board 2' of engine control systems)(prescribed by law) all values limits of the new engine E2876 LUH 03, with 320 HP, are considerably lower than those prescribed by the EEV standard. In parallel, it was possible to increase the maximum torque of 150 Nm and 1400 Nm, an almost equivalent to the motor diesel D20 comparable. While all diesel Common Rail Man engines can today meeting the EEV standard by management of both the engine and exhaust system of exhaust gases, natural gas engine is an ecological alternativeEconomic and safer for the future, especially for those companies of transport where the infrastructure and the corresponding natural gas are available at an advantageous price. From 2010, the new Man CNG engine is available both in urban low floor buses and bus chassis.
