Two Class 8 Plug-Ins for GTI for Real-World Drayage,
Battery Boost Will Avoid Expense of the ISX12 G Engine
Southern California’s US Hybrid has a contract with the Illinois-based Gas Technology Institute to fabricate and deploy two compressed natural gas-fueled Class 8 plug-in hybrid electric trucks for a year of drayage trucking trials. The plug-in CNG hybrid design is expected to reduce fuel consumption and the air quality impact associated with heavy-duty diesel emissions in ports, where trucks idle their engines for long periods while waiting in loading queues.
US Hybrid is using the Freightliner M2 112 with dedicated-CNG ISL G engine from Cummins Westport. A 300-horsepower boost from the hybrid drive “will provide a fuel performance that exceeds the much costlier [and new 11.9-liter ISX12 G] engine,” states a program summary.
“Because of hybrid efficiency, the single CNG tank can provide sufficient fuel for daily operation, which reduces tank cost and further simplifies truck integration,” states the project backgrounder. “The proposed hybrid truck will utilize the shorter wheel base of Freightliner’s day cab to provide better handling and smaller turning radius in support of the drayage operation.”
US Hybrid and Magmotor
The total GTI reimbursable project award is $1,632,268 – with US Hybrid providing $735,884 in matching funds to design, develop, manufacture and deploy the two plug-in CNG trucks – including one year of operation, service, and maintenance support for port work.
US Hybrid is providing an advanced 240-kilowatt drive system integrated with the ISL G engine with an automatic clutch to allow electric-only operation. Each truck will have 100 kilowatt-hours of onboard battery storage providing up to 30 miles of all-electric range. The production version of the vehicle, US Hybrid says, will have a smaller battery for about five miles of electric only range, “while providing the fuel savings of hybrid technologies.”
US Hybrid and its Magmotor Technologies unit will provide electric accessory items. Electric steering and air systems will augment the engine driven system for redundant reliability and operation. “An additional focus of the project is the fuel economy improvement through the optimization of the electric driven accessories.”
‘Cleanest, Most Efficient, and Commercially Viable’
“The Plug-in Hybrid technology will enhance the performance of existing CNG Class 8 trucks to meet and exceed the power availability of comparable diesel vehicles,” US Hybrid president and CEO Abas Goodarzi said in a release.
“The proposed vehicles will reduce greenhouse gas emissions by 60% with an operational cost savings of over 50%. The CNG Plug-in Hybrid is the cleanest, most efficient, and commercially viable solution for the goods movement industry,” Goodarzi said.
