GFS® Diesel Dual Fuel System

The Gaseous Fuel System™ is an innovative technology that enables operators of heavyduty diesel vehicles to substantially reduce operational costs and lower emissions. This is achieved by substituting diesel fuel with lower cost, cleaner burning natural gas. The Gaseous Fuel System™ is comprised of patented and proprietary technologies that allow diesel engines to safely operate on gas percentages ranging from 50% to 70% of the total fuel requirement. Engines converted to Gaseous Fuel™ operation exhibit diesel-like performance in such critical areas as power, response and efficiency. A key feature of the Gaseous Fuel System™ is its ability to switch fuel modes without interruption in vehicle operation.
In the event the on-board gas supply is exhausted, the Gaseous Fuel System™ will automatically switch the engine to 100% diesel operation. Conversion to Gaseous Fuel™ operation does not require modification of the engine and can typically be completed in a matter of hours. Typical applications include heavy-duty trucks, buses, refuse haulers, earth moving equipment and locomotives. The Gaseous Fuel System™ is compatible with both compressed natural gas (CNG) and liquid natural gas (LNG) fuel storage systems. [more]

GTI Bi-Fuel® System for Heavy-Duty Engines

The GTI Bi-Fuel® System from Altronic Controls is an innovative technology that enables operators of heavy-duty diesel engines to substantially reduce operational costs and lower emissions. This is achieved by substituting diesel fuel with lower cost, cleaner burning natural gas. The Bi-Fuel® System is comprised of patented technologies that allow engines to safely operate on gas percentages ranging from 50% to 75% of the total fuel requirement. Engines converted to GTI Bi-Fuel® exhibit diesel-like performance in such critical areas as efficiency, stability and load
acceptance.

A key feature of the Bi-Fuel® System is its ability to switch fuel modes without interruption in engine power output. The engine can be switched between gas automatically while maintaining speed and load. This feature gives the user the flexibility to choose between gas and diesel modes as dictated by fuel pricing, fuel availability or other operational considerations. An equally important feature of the Bi-Fuel® System is its ability to maintain engine power levels while operating in gas mode between the “continuous!’ and “prime” ratings of the engine. For operations above the programmed power limit, the engine is automatically switched to 100% diesel mode, thus avoiding the necessity to de-rate the engine. The optional Dynamic Gas Control (DGC) version of the system incorporates fuel mapping as a function of load and automatically varies the gas substitution rate for optimum performance throughout the load range.

The Bi-Fuel® System utilizes a state-of-the-art electronic control and monitoring system which monitors critical engine and Bi-Fuel® System parameters and activates or deactivates gas mode according to programmed limits. When a monitored parameter exceeds the allowable limit, the controller switches the engine to 100% diesel mode and electronically logs the fault for diagnostic purposes. The control panel is housed in a NEMA rated weatherproof enclosure and is approved for Class I, Division 2 environments. [more]
