The Natural Gas Vehicle Institute (NGVi) has updated and expanded its Heavy-Duty NGV Maintenance and Diagnostics Training.

Uniquely designed for technicians with all levels of CNG experience, NGVi says its training provides techs with comprehensive learning necessary for safe maintenance, diagnosis and repair of heavy-duty natural gas vehicles. This course covers all of the components of the CNG fuel system and has been expanded to include not only the Cummins ISL G but also the ISX12 G engine.

“We are thrilled to release this newly expanded and restructured training. Because we have in-depth understanding of both CNG fueling equipment and vehicles, we are able to give technicians knowledge and skills they can’t get from any other training provider,” says Leo Thomason, executive director of NGVi. “This is the only heavy-duty NGV technician course that covers it all. While manufacturers offer engine training, fuel system training, and other product-specific training, we cover the fuel, the CNG fuel system and the engine, in depth, in a single, comprehensive course.”

Heavy-Duty NGV Maintenance and Diagnostics Training is an intensive three-day course that helps technicians understand how gaseous fuel, the CNG fuel system, and the engine work together. It addresses the effects of carryover oil on fuel systems and engine components, which is the most significant challenge facing heavy-duty NGV technicians today, NGVi says. It covers function, failure modes, serviceability and service/repair procedures for components of all CNG fuel systems, regardless of manufacturer. On the engine side, NGVi says the course trains technicians on both routine maintenance as well as how to diagnose every major sensor and actuator unique to Cummins natural gas engines.

The enhanced engine portion of the training was developed by Gordon Larsen, NGVi’s Lead Instructor, and 40-year industry veteran with extensive experience as a technician, an NGV fleet supervisor, educator and NGV expert.

“Technicians must be able to determine the root cause of an issue, whether it was caused by fuel quality, a fuel system problem, or an engine problem,” says Larsen. “Because our training covers all three of these elements, and explains their correlation, technicians learn to quickly and accurately resolve issues. It is this root cause analysis that enables technicians to solve the problem rather than simply treat the symptom,” he added. “This ability increases technicians’ effectiveness as well as reduces unnecessary maintenance costs and vehicle downtime.”

The course is organized into 15 modules, and includes operational theory and more than a dozen hands-on exercises. It is a perfect prerequisite to fuel system or engine manufacturer training.
