Description
This course presents an introduction to comprssed natural gas (CNG) conversions and installation on vehicles. Students are required to gain an understanding of the process required to convert and install CNG systems on vehicles. Students will install CNG conversion kits on light and heavy duty vehicles. This course will focus on combining classroom instruction and theory with the opportunity to apply theory through hands-on activities performed in the lab/shop. Prerequisite: Instruction permission required.

Intended Learning Outcomes
  • Inspect the vehicle for pre-existing conditions that may adversely affect the performance of the vehicle.
  • Document pre-conversion conditions and complete all necessary reports.
  • Prepare vehicle for conversion according to manufacturer's directions.
  • Install fuel supply container with mounting hardware, valving, shielding, fuel level indicator, and remote fill assembly, as needed, using manufacturer's specifications and required local, state, and federal regulations.
  • Install pressure relief device (PRD) and venting system.
  • Select and install swage, compression, flare, captive O-ring, NPT, and other fittings using manufacturer's recommended sealants when required.
  • Install gas tight enclosure around valves and fittings, vent to the outside of vehicle as required.
  • Determine routing and protection of fuel line components according to industry standards.
  • Prepare tubing using proper techniques for cutting, deburring, cleaning, and bending.
  • Install tubing, piping, hose, and valves using appropriate chafing protection, mounting hardware, and protective shields, according to industry safety standards.
  • Determine appropriate location and mounting of the regulators; install the regulators using mounting brackets, fuel lock, fittings, starting aids, control valves, cooling lines, and thermostat as required and according to manufacturer's specifications.
  • Install fuel injection/carburetion or other fuel control components according to manufacturer's instructions.
  • Install electrical/electronic components using OEM or manufacturer's wire connections and wiring diagrams, applying all safety precautions.
  • Determine location of electrical/electronic components considering safety, serviceability, function, component protection, and esthetics according to manufaturer's specifications (when available).
  • Inspect and test each installed component to ensure it is connected and positioned in a safe and effective manner.
  • Purge and pressurize fuel system and check for system integrity through its maximum working pressure (leak test).
  • Perform system setup procedures according to manufacturer's specifications.
  • Fabricate brackets, shields, and braces according to accepted industry.
  • Complete and affix required safety/information labels.
  • Test vehicle for acceptable driveability and operation (on each fuel for dueal fuel vehicles).
  • Inspect and ensure that all required emissions control devices are present and functional; confirm that the vhicle emissions meet applicable local, state, and federal requirements.
  • Perform pre and post conversion emissions evaluation.
