Why Take Heavy-Duty Training?
The number of heavy-duty vehicles powered by alternative fuels is growing every year. Mandates such as the federal Energy Policy Act and the California Federal Pilot Program 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 gaseous fuel system, engine, electronics, and exhaust.
For an experienced diesel technician, the greatest challenges when working with AFVs include the concepts of working with fuels such as natural gas and propane, emission-control equipment, electronic ignition, and safety. Each chapter of the Technician’s Manual contains text, illustrations, explanatory figures and tables, chapter review questions, and job aids, along with classroom and/or shop activities.
Each corresponding chapter of the Instructor’s Manual contains everything in the Technician’s Manual, as well as a detailed daily agenda, teaching suggestions, group discussion topics, chapter review questions with answers, PowerPoint slides, and animated presentations.
The National Alternative Fuels Training Consortium (NAFTC) is pleased to offer this course, Heavy-Duty Gaseous Fuel Applications, which meets the needs of the technician, the employer, the fleet operator, and the training institution.
Course Objectives
Taught by certified NAFTC instructors, this course will enable you to:
- Explain the sources and processing of hydrocarbon gaseous fuels
- Discuss the impact of dependence on foreign oil on the U.S. economy
- Describe the sources and effects of environmental pollution
- List the major alternative fuels currently or soon to be in use, and compare the benefits and drawbacks of each
