What happens to truck weight when converting a truck to dual fuel?

The weight of APG’s Dual Fuel System is nominal, however the tank package will add weight to the truck depending on fuel tank capacity and storage solution. Contact APG to discuss size and range options. Regarding the total weight of the entire truck/trailer unit, the total on-road weight may exceed the GVWR guidelines. Fleets should consult with their local and federal legislatures to determine if any exceptions would apply to units running dual fuel.

Can APG’s Dual Fuel Technology be transferred to another engine?

Yes. APG’s Dual Fuel Technology can be transferred to another engine within APG’s current listing of engine families that are compliant with EPA Memo 1A or EPA CAFC regulations. Once the hardware of the Dual Fuel System is reinstalled, APG’s ECU will need to be re-flashed by an APG Certified Installer in order to have the appropriate software installed. The original unit is then able to operate on 100% diesel just as it was before the Dual Fuel upgrade occurred.

What are the economic benefits to operating on dual fuel?

Annual fuel savings resulting from operating in an APG Dual Fuel mode range from 10% to 40% and will vary according to the respective costs of diesel and natural gas fuel pricing. Other economic benefits include competitive advantages such as utilization of sequestered natural gas, low cost of ownership, and freedom to hedge against future unknown risks of the price of diesel versus natural gas.

What does all this do to manufacturers’ warranties?

APG does not change the base diesel engine design and warrants the Dual Fuel System components for one year after installation. Industry documentation and regulations cite the following in regard to the effects of an approved aftermarket technology on OEM warranties:

  • Magnuson-Moss Warranty Act of 1975 says the consumer has the freedom to choose aftermarket parts and upgrades without having the OEM warranty voided.
  • The Federal Trade Commission (FTC) issued a Consumer Alert in January 2011 confirming that it is in fact illegal to void warranties or deny coverage for the use of an aftermarket part.
  • Specifically in the EPA Alternate Fuel Conversions final rule published on April 8, 2011
    • http://www.gpo.gov/fdsys/pkg/FR-2011-04-08/pdf/2011-7910.pdf
      • “… the clean alternative fuel conversion manufacturer would normally be held
      • accountable for fixing problems that occur as the result of conversion…”
        “… the OEM would generally retain responsibility for the performance of any parts or systems that retain their original function following conversion and are unaffected by the conversion…”

Will my engine run hotter on dual fuel?

The dual fuel technology has been designed to maintain OEM specifications of all engine temperatures including engine coolant temperature, oil temperature, exhaust gas temperature and intake air temperature. The Dual Fuel System replaces diesel fuel normally consumed by the engine with an equivalent quantity of natural gas, relative to the heat value of each fuel. As such, engine air-fuel ratios during dual fuel operation remain largely equivalent to 100% diesel operation, resulting in normal peak exhaust gas temperatures and associated peak engine thermal loads.
