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

CNG Fuel System Design and Installation Training

Intended for design engineers, installation technicians and quality assurance teams, this training provides the instruction and comprehensive learning necessary to design and install CNG fuel systems that will comply with all applicable safety codes and standards.

The course teaches students about all CNG fuel system components and their functions, as well as how to treat CNG cylinders during the fuel system installation process, and how to assess potential damage that may occur prior to or during installation. Special emphasis is placed on properly understanding and applying the codes and standards governing CNG fuel system installation.
