Cummins Westport ISB6.7 G midrange natural gas engine now in full production
December 09, 2016
Cummins Westport’s ISB6.7 G, a 6.7 liter midrange, factory-built natural gas engine is now fully available as a production engine for shuttle bus, medium duty truck, and vocational applications in North America. (Earlier post.) As previously announced, the engine has been available for school bus applications since May 2016 from Thomas Built Buses. The 6.7 liter engine platform has large OEM availability for midrange trucks, vocational trucks and mid size buses and the expansion of applications potentially available for the ISB6.7 G engine more than doubles its addressable market.
The ISB6.7 G is based on the Cummins ISB6.7 diesel engine platform, the industry leader in the Cummins midrange engine family, and operates exclusively on natural gas, including compressed, liquid, or renewable natural gas (RNG). The ISB6.7 G is the second engine from Cummins Westport (CWI) to receive emission certification from the US Environmental Protection Agency (EPA) and the Air Resources Board (ARB) in California for meeting the Optional Low NOx Emissions standards.
New Icon-class ships from Royal Caribbean to be powered by LNG with 2022 delivery; testing hydrogen fuel cells in 2017
October 11, 2016
The newest class of ships from Royal Caribbean Cruises Ltd (RCL) will be powered by liquefied natural gas (LNG) and likely will introduce the use of fuel cell technology, ushering in a new era of shipbuilding that will significantly reduce greenhouse gas emissions. The ships will join the fleet of Royal Caribbean International.
RCL has signed a memorandum of understanding with Finland shipbuilder Meyer Turku for the new class of vessel under the project name “Icon.” The around 200,000 gross ton large cruise ships will be delivered in the second quarters of 2022 and 2024. In the meantime, the company said, it will begin testing fuel cell technology on an existing Oasis-class ship in 2017, and will also run progressively larger fuel cell projects on new Quantum class vessels being built in the next several years.
Volkswagen Group opts for LNG-fueled car carriers
October 06, 2016
From 2019, Volkswagen Group Logistics will use two LNG-powered charter vessels from Siem Car Carriers AS, making it one of the first automakers to opt for low-emission LNG-powered vessels for the marine transport of vehicles. The two ships, with a length of 200 m and a capacity of about 4,500 vehicles, are to be used for vehicle shipment between Europe and North America. The use of LNG-powered roll on/roll off (RORO) car carriers on other routes is currently being considered.
Alternative LNG drive systems for ships reduce air pollutant emissions significantly—CO2 by up to 25% and NOx by up to 30%, particulate matter by up to 60% and SOx by as much as 100%. Emissions will be further reduced by the use of an advanced dual-fuel marine engine with direct injection and exhaust gas treatment.
GD Tech delivers prototype direct-CNG injectors to Fiat Powertrain for 13L IVECO engine; HDGas project
September 24, 2016
GDTech Engineering s.a. has developed and delivered prototype direct-CNG injectors to Fiat Powertrain for heavy-duty long-haul LNG mono-fuel engines.
This injector will be applied in the future IVECO Cursor 13 DI-CNG engine being developed as part of the HDGas project in Europe. GDTech is the injector supplier to Fiat Powertrain Technology Industrial (which is in charge of the development of new IVECO engines for coaches, buses & industrial applications).
