The manufacturer announced it is adding trucks with NGV drives to its established range of natural gas city buses in 2016. At the IAA 2014, MAN is giving a preview of the CNG technology in trucks with a TGM distributor chassis. The 18-tonner is driven by a six-cylinder gas engine with 280 hp from 6.9 l displacement and is equipped with a 12-speed MAN TipMatic gearbox. The Euro 6 turbo engine has a maximum torque of 1150 Nm and thus provides the same tractive force as a diesel engine of this performance class.
The tank at the IAA exhibit holds 140 kg of natural gas, which is stored in eight compact aluminum tanks with carbon coating. Steel tanks able to hold up to 140 kg natural gas are also available. This tank capacity allows 18-tonners to cover some 400 km in distributor urban transport and around 700 km on secondary roads. Due to this wide range, the trucks are not only of interest to municipalities with gas-powered fleets and their own filling stations.
In addition, the TGM with CNG drive is up to 3 dB quieter in interior noise and accelerated drive-by. This value means the sound intensity is halved. Thus, these vehicles are particularly suitable for tasks in cities and usage in the early morning or late in the evening, for which there are particular noise restrictions.
CNG trucks can be used for food and coolant transportation in the distribution segment, parcel services and as retail delivery trucks. The use of municipal vehicles for waste collection is typical in the industry.
