The number one challenge facing heavy-duty NGV technicians is how to distinguish between a fuel quality problem, a fuel system problem or an engine problem. This course is the only training available that treats these three elements as a system and helps technicians understand how they are interrelated. Emphasis is placed on the safety knowledge and repair practices that are unique for heavy-duty natural gas engines. The course covers the components of all CNG fuel systems (regardless of manufacturer), as well as the Cummins ISL G and ISX12 G engines.

The course includes operational theory with more than a dozen hands-on exercises. It is a perfect prerequisite to fuel system or engine manufacturer training. This course also helps prepare technicians for the ASE H1 exam.

The learning objectives for this course include:

  • Identify and compare the properties and characteristics of CNG and LNG to diesel
  • Describe the safety procedures necessary to maintain and repair CNG and LNG vehicles
  • Identify and describe the operation, maintenance, diagnostics, and repair of the low- and high-pressure components of a CNG fuel system
  • Properly assemble and re-assemble high-pressure tube fittings following safe procedures
  • Identify the unique components and operation of the Cummins ISL G and ISX12 G engines and emissions control system
  • Identify and describe fuel system and engine component maintenance intervals and procedures unique to Cummins powered NGVs
  • Describe basic diagnostic procedures for Cummins ISL G and ISX12 G engines
  • Identify diagnostic procedures and interpret data for electrical related issues, sensors and solenoids using wiring diagrams and other tools
  • Diagnose hard starting and/or poor drivability issues
  • Identify unique components and operation of LNG (saturated) and HPDI (unsaturated) LNG fuel systems
  • Increase the technician’s knowledge and preparation for successful completion of the Cummins ISL G and ISX12 G engine certification and/or the ASE H1 Alternative Fuels certification exam

Presenter: TBD

Cost: $190 per person. PPTA cancellation policy applies.

Shuttle Transport: CATA has very limited parking options at this time. To best accommodate you, CATA is providing a shuttle, which will depart from the front of the Courtyard by Marriott twenty (20) minutes before the training is scheduled to begin. The Courtyard is located at 1730 University Drive, State College, PA 16801, and parking there is free and plentiful. The shuttle will return to the Courtyard at the conclusion of each day’s training. Please utilize this shuttle to avoid parking at CATA and potentially impacting their operations.

Lodging: PennTRAIN has secured a block of rooms at the Courtyard by Marriott, located at 1730 University Drive, State College, PA 16801, for the nights of December 8-12 at the government rate of $101/night plus taxes. Click here to book online, or call 814-238-1881 and ask for the PennTRAIN block. Rooms will be released on November 15, or when sold out.

Meals: Breakfast, lunch, and breaks will be provided. Please inform Sara Bowden at of any dietary restrictions at least one week in advance.

Attire: Casual. Parts of the training will be held in a classroom, and other parts in the maintenance shop. Please dress accordingly. Because it can be a challenge to keep the meeting room at a temperature that accommodates everyone, we recommend bringing a sweater or jacket to stay comfortable.
