    Characteristics of the GTI Bi-Fuel System

    Below are some of the advantages of using Bi-Fuel System:

    • High efficiency
    • Compression ignition
    • Low gas supply pressure
    • Sophisticated Altronic engine protection system
    • Auto-switching of fuel modes
    • Non-intrusive, simple installation
    • Easy to operate
    Benefits to the User

    • Reduced energy costs
    • "Fuel flexibility"
    • Reduced exhaust emissions
    • Rapid payback
    • Extended run-time for emergency operation
    Bi-Fuel-Equipped Diesel Engines vs. Dedicated Gas Engines

    Compared to dedicated gas engines, the bi-fuel equipped diesel engines offer the following advantages:

    • Lower initial cost
    • "Fuel flexibility"
    • Higher efficiency
    • Reduced O&M costs
    • Smaller physical "footprint" vs. output
    Compatible Fuel Gases

    The fuel gases that are compatible to GTI Bi-Fuel Systems are:

    • Pipeline natural gas
    • Well-head gas
    • Liquid natural gas (LNG)
    • Compressed natural gas (CNG)
    • Bio-gas (landfill, wastewater)
    • Coal-bed gas
    Composition of Natural Gas

    High quality pipeline gas has the following composition in percentage volume:

    • Methane 97.09%
    • Ethane 0.88%
    • Propane 0.26%
    • Butane 0.09%
    • Nitrogen 1.41%
    • Carbon Dioxide 0.12%
    • Oxygen 0%

    Time and Manpower Requirements for Conversion

    Conversion time will depend on the size and complexity of the application. Generally, one to two days will be required for smaller engines, while larger engines might require two to four days. In either case, manpower required is usually limited to between one and three technicians.

    Lowered Pollution Levels

    The chart below shows the impact of the GTI Bi-Fuel System and an SCR Catalyst on NOx levels.

    As it is show very clearly the NOx levels are very much lowered with the Bi-Fuel Technologies.
