Liquified Natural Gas Vehicles Module 0

  • This instructor’s manual is a five-day training program for technicians and fleet personnel who work with liquefied natural gas (LNG) vehicles, especially heavy-duty applications.

    Purpose and context

    • LNG is presented as a cleaner-burning alternative to gasoline and diesel that can help reduce transportation costs, emissions, and reliance on imported oil.
    • The manual links growing alternative-fuel vehicle use to regulatory mandates and fleet needs, creating demand for technicians trained in LNG systems.
    • It emphasizes that heavy-duty vehicles consume substantial fuel, making LNG particularly relevant for large fleets and long-distance operations.

    What the course teaches

    The course develops both technical knowledge and safe work practices across ten chapters:

    1. Alternative fuels: Overview of ethanol, methanol, CNG, LNG, propane, hydrogen, electric/hybrid vehicles, and fuel cells.
    2. Gaseous-fuel fundamentals: Sources, processing, economic impacts, and environmental implications of natural gas and other gaseous fuels.
    3. Pressure, temperature, and density: Measurement concepts and hands-on use of instruments.
    4. Fuel properties: Chemical and physical characteristics of LNG and related emissions considerations.
    5. Combustion and engine design: Four-stroke and diesel cycles, air-fuel ratios, lean-burn operation, timing, compression, and engine components.
    6. LNG fuel systems: Tanks, fueling, venting, defueling, lines, valves, regulators, and pressure-relief devices.
    7. Electronic controls: ECU operation, sensors, monitors, and actuators.
    8. Ignition systems: Electrical fundamentals, coils, capacitors, inductance, secondary ignition, and spark plugs.
    9. Safety, maintenance, and inspection: Personal and shop safety, leak/fire/spill response, emergency preparation, and applicable requirements.
    10. Fleet management: LNG transportation, delivery, storage, gas detection, fire suppression, tank management, staff training, standards, and preventive maintenance.

    Training design

    • The program is designed for experienced diesel technicians adapting to LNG-specific challenges, including cryogenic fuel systems, emissions controls, electronic ignition, and safety.
    • It combines classroom instruction with heavy-duty vehicle laboratory activities.
    • The instructor version includes daily agendas, teaching suggestions, discussion topics, review answers, slides, and animated presentations; the technician version provides instructional content, illustrations, review questions, and job aids.
    • The schedule spans five eight-hour days, with approximately 6.5 instructional hours per day.

    Core outcomes

    Graduates should be able to explain LNG and gaseous-fuel properties; understand combustion and electronic/ignition controls; identify and service fuel-system components; apply safety and emergency procedures; follow relevant policies and inspection requirements; and recognize LNG training needs within fleet operations.

    Important limitation

    The manual is educational guidance rather than a substitute for manufacturer instructions, legal requirements, safety codes, or current standards. It cautions users to obtain the latest version because technical information and links may change.
