Iveco begins deliveries of heavy-duty Euro VI natural gas trucks
7 May 2014
Iveco has begun deliveries of the first units of Stralis Natural Power Euro VI, the new heavy-duty range of natural gas-powered vehicles. Iveco offers a complete range of light-, medium- and heavy-duty commercial vehicles as well as buses powered by natural gas. A total of more than 12,000 units have been sold to date, 2,000 of which were sold in 2013.
The new Stralis Natural Power Euro VI with 2 and 3-axle rigids and 2-axle tractors are fitted with a Cursor 8 Natural Power engine, ranging from 270 to 330 hp. The engine is coupled to a 16-gear manual ZF transmission or 6-speed Allison automatic transmission with hydraulic torque converter. CNG models have an overall tank capacity ranging between 400 to 1,300 liters with layouts that can be tailored to suit customer needs.
Along with the CNG version, for medium- and long-range missions the Stralis Natural Power is available also with LNG for a cruising range of 750 km (466 miles). The tractor AT440S33T/P LNG, in standard configuration, is equipped with 4 x 70-liter CNG tanks and a 525-liter LNG cryogenic tank. Natural gas is stored in its liquid state at -130 °C and at 9-bar pressure, which is then converted into a gaseous state before being injected into the engine.
Iveco is the only European manufacturer to have confirmed its CNG technology strategy in the evolution from Euro V to Euro VI: natural gas FPT Industrial engines are characterized by stoichiometric combustion; 100% fueled by natural gas; and Otto cycle with spark plugs that ignite the air-fuel mixture injected by a rail, with two injectors per cylinder. Exhaust gas is treated by a standard passive three-way catalyst that does not require the use of any additives.
With regards to emissions, Euro VI natural gas engines are much “greener” than their Euro VI Diesel counterpart. Natural gas PM emissions are 95% lower in comparison to diesel, and 35% lower in NOx. These vehicles make it possible to reduce vehicle CO2 emissions from 10% up to 100% if bio-methane is used. Lastly, Iveco proposes a quieter vehicle with an average decrease of 5 decibels in comparison to diesel models.
In terms of cost efficiency, overall TCO (Total Cost of Ownership) savings stand at up to 10%.
