Mining's LNG Hybrid Conversion

摘要

In October 2010, Gaseous Fuel Systems (GFS) unveiled its first liquid natural gas (LNG) mining truck. Its bi-fuel conversion system allows the Cat 777C to operate on 60 percent gas substitution for diesel. In June 2012, the EVO-MT 7930 conversion system was introduced to modify the Caterpillar 793 haul truck, followed by the EVO-MT 7770 for the Cat 777 truck. Both systems seamlessly switch to 100 percent diesel operation in the event of a fault condition or low LNG fuel levels. The company's bi-fuel conversion systems substitute 50 to 60 percent of its fuel to LNG.
