What is Bi-Fuel®?• Bi-Fuel® is a “co-firing” of standarddiesel fuel and natural gas(methane)• It is designed for use onconventional, heavy-duty dieselengines• No engine modifications arerequired• The GTI Bi-Fuel® Systems can beinstalled in the field oraccomplished as an OEM up-fit• Natural gas typically substitutesup to70% of the diesel fuelrequired to maintain a givenspeed and load
Characteristics of theGTI Bi-Fuel® System• Maintains diesel-like performance andefficiency• Compression ignition• Low gas supply pressure• Sophisticated Altronic engine protectionsystem• Auto-switching of fuel modes• Non-intrusive, simple installation• Easy to operate

Benefits to the User• Reduced energy costs• Interruptible gas andelectric rates• “Fuel flexibility”• Reduced exhaustemissions• Rapid payback• Extended run-time foremergency operation
Specific Advantages of Bi-Fuel®Operation for Stand-By Service• Extended run-time vs. amount of fuel stored• Reduced exposure to environmentalliabilities (smaller or above-ground dieselstorage tanks)• Reduced utility costs for both gas andelectricity by qualifying for interruptible rates• Decreased visual emissions during systemtesting/validation
Extended Run-Time with theGTI Bi-Fuel® System• 100% Diesel vs. GTI Bi-Fuel® Run-Timeon a 1000KW load– Diesel Fuel Rate: 54 gallons/hour– Fuel Storage Capacity: 1500 gallons– 100% Diesel Run-Time: 28 hours– Bi-Fuel® Gas Substitution Rate: 70%– 70% Gas Run-Time: 93+ hours

GTI –Altronic Statement• Subject: GTI Bi-Fuel Emissions• Conversion of any diesel engine to GTI Bi-Fuel will generallyprovide for reductions in harmful emissions. The extent of theseemissions reductions will depend on a number of factorsincluding age and condition of the engine, engine make andmodel, load factor, diesel injection system design, as well as thequality and composition of the supplied natural gas. In generalterms, GTI Bi-Fuel will reduce NOx, NMHC (non-methanehydrocarbons), SOx, PM and opacity. Note that NMHC and Noxare ozone precursor emissions; these emissions react in thepresence of sunlight to form ozone (smog). Bi-fueled dieselengines will typically have 20% to 50% lower ozone pre-cursoremissions. Additionally, pipeline quality natural gas has little orno sulfur content and as such, converted engines will typicallyproduce 50% to 80% less SOx compared to 100% dieseloperation.• While the above listed benefits do generally occur, the degree towhich this happens will vary from engine model to engine model,as well as from engine to engine within the same engine modelclass.
GTI –Altronic Statement• Based on a broad experience with the GTI Bi-Fuel System,we are confident that operation of gensets on Bi-Fuel willproduce 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.
GTI –Altronic Statement• CO output will increase during Bi-Fuel operation as well asthe total hydrocarbon (THC) output. If the lowest possibleCO and THC output are desired, a 2-way catalysts can beused which will decrease these emissions approximately70% - 90%, depending on load factor.• The numbers and percentages listed in this documentshould not be used for quoting purposes or looked at as aspecification.
