New Engines Westport said it has continued the development of the GX natural gas engine to offer emissions performance while maintaining equal horsepower, torque and efficiency to a diesel engine. The application of Westport high-pressure direct injection (HPDI) technology to the Cummins ISX en- gine reduces emissions to below EPA 2010 heavy-duty on- road application requirements, the company said. The Westport GX engine is available through Paccar.
Emissions Technology The 2010 Westport GX engine is based on the 2009 Cummins ISX 15 L engine and uses Westport HPDI technol- ogy along with the base engine’s cooled EGR technology and a chassis-mounted SCR system to meet the EPA 2010 emissions certification level. Engine ratings have been increased over the previous product with the addition of a higher power rating of 475 hp. The 2010 GX engine is available with power ratings from 400 to 475 hp and torque ratings of 1450 to 1750 lb.ft. LNG fuel for the Westport GX engine is stored in an LNG tank, and drawn out with a pump powered by hydraulic oil from an engine-driven hydraulic pump. The LNG is vapor- ized — using excess heat from the engine coolant — and exits the tank module at approximately 100°F and 4500 psi. The warm, high-pressure gas is filtered and passed through an accumulator vessel that dampens pressure fluctuations and provides natural gas for engine start-up. At the same time, a diesel fuel pump draws and pressurizes
