Inspection Guidelines for CNG & LPG Vehicle Conversions

CNG and LPG Vehicle
Purchasing Inspection
Guidelines
> January 2014

Statement of Purpose
Agenda

• Consumer expectations for CNG and LPG
vehicle purchases
• Inspection requirements for CNG and LPG
vehicles
• Finding a qualified individual to conduct safety
inspections

• Training for inspectors
• Inspection checklist
2

Converted CNG Vehicle Purchase
Guidance: Do some research.
1. US EPA and CARB certified conversion kits and engine
platforms are allowable under current federal regulation.
•

NGVA List:

inal.pdf

•

EPA Website: Certified Clean Alternative Fuel Conversion Systems
http://www.epa.gov/otaq/consumer/fuels/altfuels/documents/certifiedconversions.xls

2. Converters need to be approved by kit manufacturer. It is
preferred to confirm converter has ASE/CSA qualified
technicians installing conversion kits.
3

Converted CNG Vehicle Purchase
(Continued)
3. Expand knowledge base. Use the following documents
to educate yourself in the basics.
• “Have Your Vehicle Converted to Compressed Natural GasSafety”, Clean Vehicle Education Foundation
(http://www.cleanvehicle.org/committee/technical/PDFs/Con
vert_Your_Vehicle_Safely_Final.pdf).
• “Fact Sheet: Converting Light Duty Vehicles to Natural
Gas”, NGVAmerica
(http://www.ngvc.org/pdfs/FAQs_Converting_to_NGVs.pdf.)

4. Determine fueling logistics. Want to identify and secure
at lease two fueling options.
4

CNG Vehicle Inspection
Guidance: Know the facts.
1. ANSI NGV 2 (fuel tank spec) requires an
inspection of the fuel tank every 3 years.
2. TP-304-03 FMVSS (CNG Fuel Container Integrity),
National Highway Traffic Safety Administration
requires additional “or 36,000 miles” for tank
inspection.
3. NFPA 52 requires that a tank is inspected
─ After an accident or fire
─ Before it is reinstalled in a vehicle
5

CNG Vehicle Inspection (Continued)
4. The Compressed Gas Association (CGA) defines a
qualified inspector as:
• 2 years experience conducting inspections
• Supervision by person with 2 years experience conducting
inspections
• Approved by fuel cylinder manufacturer
• Certification from original equipment manufacturer through
training center
• Certification from nationally recognized organization e.g.
CSA
• Certification as inspector by Authority Having Jurisdiction
6

CNG Vehicle Inspection (Continued)
Finding an certified inspector:
• CSA provides certification for CNG fuel system inspection
which includes all major components and tanks.
• CSA offers a list of qualified and certified fuel system
inspectors on their website.

• www.autogasusa.org
10

LPG Vehicle Purchase (Continued)
4. Determine fueling logistics. You may want to
secure at lease two fueling options.

11

LPG Vehicle Inspection
1. Propane containers are certified by ASME or DOT
•

DOT cylinders are mainly used for industrial and off
road applications such as forklifts, mowers, etc.

2. NFPA 58 states fuel containers have to be
requalified per Compressed Gas Association
inspection criteria. Good practice to include
vehicles involved in fire and/or auto accidents.
3. Follow OEM specifications for inspections/training.

4. NFPA 58 requires vehicle fuel system to be leak
free prior to garage storage or service.
12

Municipal/Licensing Entity LPG
Vehicle Inspection
• GTI is preparing a template checklist for inspection
of LPG vehicles
• Checklist will be accessible on CACC, WICC, and SSCC
websites

• Checklist is NOT a substitute for experienced
vehicle inspections

13

Propane Autogas Tank Safety Features


The tank mounting plates are structurally
mounted to the floor or frame using a total
of (10) M12 bolts, with backing plates in all
locations that do not already have a Ford
structural anchor.



The tank is then isolation-mounted to
these plates, providing structural and noise
isolation between the tank and the floor so
that any body flex does not result in
stresses on the tank.



This system is designed to ROUSH
CleanTech‟s internal mounting standards
(tank will not become dislodged in 20g
front crash, 8g side / rear) which is double
the NFPA standard.



This ensures that the tank itself does not
become dislodged in an accident.

Barnes Green Energy was created to provide alternatives to
conventional fuels which are not only cost effective but
provide a “Green Solution” to vehicle fleet owners and
managers

•

The US Dept of Energy now forecasts a growing supply of natural gas
that extends into the next century. New technologies that have
evolved allow natural gas production to ramp up to a level not
foreseen a decade ago.

•

To take advantage of this natural gas fuel abundance, and the
resulting price advantage at the pump, Barnes Green Energy (BGE)
was organized in April 2013 to develop infrastructure and provide fuel
system conversions for compressed natural gas as a vehicle fuel.

•

BGE not only provides EPA Certified Natural Gas (CNG) fuel system
conversions but offers a CNG fueling facility at our Nesbitt Road
location in Madison in partnership with U.S. Oil/Gain Clean Fuel,
which will come on line in the Spring of 2014.

Fuel System Conversions
•BGE along with its business partner Barnes Power Equipment (BPE), have
converted thirty vehicles to CNG fueling since starting in the fall of 2012.
Of these, twenty conversions are for the Barnes Inc. fleet. The remaining
ten are for other fleet owners such as United Beverage, Great Lakes
Conservation Corp., UW Provision, Center Point Energies, and others.
•BPE employs Certified Technicians for CNG conversions for GM,
Chrysler (NatGasCar ) and Ford ( Altech Eco ) using conversion systems
provided by the major CNG fueling system providers noted above.

Timeline for conversions
Typical conversions will take 2 – 3 days for completion once the
pieces / parts have arrived at our shop in Madison.
Conversion Costs
Costs for conversions vary depending on vehicle make, year, engine
size, original fuel type ( gasoline or diesel ), and number and size
of tanks installed. The number and size of tanks are a major cost
component in conversions, and are driven by desired range for the
vehicle, among other considerations.

There are three types of aftermarket conversions currently
available.
The most common conversion is “U.S. EPA Certified”, and covers
the current model year as well as the previous two model year’s
vehicles.
The second type of conversion is commonly called “Intermediate
- Approval by U.S. EPA”, and the third type is “Outside Useful
Life - Approval by U.S. EPA”
The link below will take you to a complete listing of vehicles and
engines for which conversions are available:
http://www.ngvamerica.org/pdfs/Available_Vehicles_and_Engines.pdf

CNG Cylinders ( tanks )

Presently there are four types of tanks available, designated by a
number.
Type 1 tanks are all metal, steel or aluminum; Type 2 are a metal
liner hoop wrapped with a composite material, usually fiberglass
or carbon fiber. Type 3 tanks also use a metal liner but the liner is
completely covered by the composite material. Type 4 tanks are
composed of a gas tight plastic inner cylinder fully enclosed by a
composite covering.

Pricing for these tanks escalates rapidly as you move from Type 1
to Type 4 tanks.
