The number of trucks and buses powered by liquefied natural gas (LNG) is growing every year. Mandates such as the federal Energy Policy Act require most large fleets to include alternative fuel vehicles (AFVs) in ever-growing numbers.
All of this means that the demand for AFV technicians is increasing dramatically. The AFV technician needs to know everything that is currently applicable to heavy-duty vehicles, along with new technology to deal with the LNG fuel system, engine, electronics, and exhaust. This course meets the needs of the technician, the employer, the fleet operator, and the training institution.
Course Objectives
