Primary Education Coursework

Electric Auto Shop has developed a comprehensive course to instruct Compressed Natural Gas (CNG) technology.

CNG Conversion Class Overview  

Course Goal: To introduce high school, vocational, college, and technical school students about the design and construction of flex fuel vehicles.  The course involves modifying an internal combustion engine (ICE) vehicle to run on its natural fuel and CNG.  Instructor Training is available for this curriculum.  The course works with gasoline and diesel fueled vehicles.

This course follows the strict guidelines of CSA & NFPA 52 regulation.  Graduates earn the highest level of certification available and gain the confidence needed to safely install and maintain compressed natural gas systems. Once completed, the course work qualifies students to apply become a CNG Preferred Installer.

Students will learn:

Essential #1: High Pressure Tank and Line Installation
This element of the coursework stresses Safety & Hazard Mitigation.  Students learn inspection of high pressure cylinders.  This includes knowledge of cylinder parts, methods of construction, valves, and PRDs.  Cylinder de-fueling techniques are described in specific detail, along with hazard mitigation and storage procedures.

Essential #2: Under-the-Hood Component Installation
Students will see and compare different manufacturer's conversion systems. They will understand basic components and wiring in aspirated and sequential port injection system types.  They will learn specific step-by-step installation sequences for the kit included with the course and understand the tools used in conversion.

Essential #3: Vehicle & Computer Calibration
Students learn the skills required for adjusting and fine tuning for optimal CNG performance.  They will use laptop calibration software to calibrate for these factors: outside temperature, altitude, load, barometric pressure and cylinder type.

Essential #4. Diagnostics
Students learn Problem Solving & System Troubleshooting.  This section of the coursework focuses on system troubleshooting.  Student are given a series of hidden problems and learn to diagnose via system checklists. These real time skills prepare them for diagnostics they will use in actual service situations.
