|The eTec Silverado HICE.|
Electric Transportation Engineering Corporation (eTec), a wholly owned subsidiary of ECOtality, Inc. is delivering an eTec Hydrogen Internal Combustion Engine (HICE) Silverado truck to the Center for Hydrogen Research (CHR) in Aiken, South Carolina.
Based on a modified 2007 Silverado 1500HD full-size pickup truck with a Vortec 6.0L V-8 engine, the HICE Silverado delivers 146 kW (195 hp) of power with 352 Nm (260 lb-ft) or torque. It has a 147 mile (237 km) city range and 210 mile (339 km) highway range, with a top speed of 100 mph. Fuel consumption is 14 miles (22.5 km)/kg city, 20 mpg (32.3 km)/kg highway.
eTec worked with project partners Roush Industries and Powertech Labs on the conversion. The development program focused on a lean-burn strategy to achieve very low NOx emissions while maintaining acceptable horsepower and torque. eTec integrated a Lysholm supercharger to the intake manifold and a large liquid-to-air intercooler to provide the added air-boost to meet the lean-burn requirement.
Gaseous fuel injectors designed for use with hydrogen are installed on the engine using custom fuel rails with fuel temperature and pressure sensors.
Additional engine modifications include the integration of an OEM electronic throttle and replacement of the standard spark plugs with custom plugs designed to operate in the Hydrogen fuel environment.
eTec removed the OEM Powertrain Control Module (PCM) and replaced it with an aftermarket PCM using eTEc developed engine control strategies for hydrogen lean-burn operation.
Three 150 liter Type 3 tanks mounted in the bed of the pickup hold 10.5 kg of hydrogen at 350 bar (5,000 psi).
Purchased by the CHR, the eTec HICE Silverado is the first hydrogen vehicle to be registered in South Carolina and will be used to publicly demonstrate using hydrogen in transportation. To fund this project, the CHR received a $175,000 grant from the Washington Division of URS Corporation.
Although eTec currently has several HICE vehicles in operation in Canada participating in the Integrated Wasted Hydrogen Utilization Project (IWHUP) (earlier post), and has orders for other HICE vehicles for US customers, the eTec HICE Silverado delivered to the Center for Hydrogen Research is the first eTec HICE vehicle to be registered and operated in the United States.
