NGVi is now more than natural gas. Welcome to the new Alternative Fuel Vehicle Institute – AFVi!

Vehicle Training Level 1 NGV Essentials and Safety Practices

With a focus on safety, this one-day course teaches technicians and support team members the fundamentals of working with natural gas as a vehicle fuel and both CNG and LNG fuel systems.

Natural gas behaves differently than gasoline or diesel fuels and, on CNG vehicles, portions of the fuel system operate at extremely high pressures (3,600 psi). LNG vehicles use cryogenic (-260 degrees Fahrenheit) fuel systems. While both types of fuel systems are very safe, they require unique components and special safety procedures for all levels of routine maintenance, diagnostics and repair.

This course is now available in two versions to fit your training needs:  CNG only or CNG/LNG.

This on-demand e-learning course takes approximately 2.5 (CNG) to 3 (CNG/LNG) hours to complete.
