5. What is Bi-Fuel®?
• Bi-Fuel® is a “co-firing” of standard
diesel fuel and natural gas
(methane)
• It is designed for use on
conventional, heavy-duty diesel
engines
• No engine modifications are
required
• The GTI Bi-Fuel® Systems can be
installed in the field or
accomplished as an OEM up-fit
• Natural gas typically substitutes
up to70% of the diesel fuel
required to maintain a given
speed and load
6. Primary Applications
• Prime power
• Peak shaving
• Standby power
• Distributed power
generation
• Pumping
applications

emergency operation
10. Specific Advantages of Bi-Fuel®
Operation for Stand-By Service
• Extended run-time vs. amount of fuel stored
• Reduced exposure to environmental
liabilities (smaller or above-ground diesel
storage tanks)
• Reduced utility costs for both gas and
electricity by qualifying for interruptible rates
• Decreased visual emissions during system
testing/validation
11. Extended Run-Time with the

22. GTI –Altronic Statement
• Subject: GTI Bi-Fuel Emissions
• Conversion of any diesel engine to GTI Bi-Fuel will generally
provide for reductions in harmful emissions. The extent of these
emissions reductions will depend on a number of factors
including age and condition of the engine, engine make and
model, load factor, diesel injection system design, as well as the
quality and composition of the supplied natural gas. In general
terms, GTI Bi-Fuel will reduce NOx, NMHC (non-methane
hydrocarbons), SOx, PM and opacity. Note that NMHC and Nox
are ozone precursor emissions; these emissions react in the
presence of sunlight to form ozone (smog). Bi-fueled diesel
engines will typically have 20% to 50% lower ozone pre-cursor
emissions. Additionally, pipeline quality natural gas has little or
no sulfur content and as such, converted engines will typically
produce 50% to 80% less SOx compared to 100% diesel
operation.
• While the above listed benefits do generally occur, the degree to
which this happens will vary from engine model to engine model,
as well as from engine to engine within the same engine model
class.
23. GTI –Altronic Statement
• Based on a broad experience with the GTI Bi-Fuel System,
we are confident that operation of gensets on Bi-Fuel will
produce emissions reductions in the following ranges:
• 1. NOx: 10% - 30% decrease
• 2. HC (reactive): 20% - 80% decrease
• 3. PM-10: 20% - 50% decrease
• 4. Opacity: 30% - 50% decrease
• 5. SOx: 50% - 70% decrease.
24. GTI –Altronic Statement
• CO output will increase during Bi-Fuel operation as well as
the total hydrocarbon (THC) output. If the lowest possible
CO and THC output are desired, a 2-way catalysts can be
used which will decrease these emissions approximately
70% - 90%, depending on load factor.
