Specialty Products > GTI Bi-Fuel® System for Heavy-Duty Engines Overview
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 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. Operation & Performance In the typical configuration, gas is introduced at a location downstream of the engine air cleaner and upstream of the turbocharger. The gas is supplied at approximately atmospheric pressure using a proprietary airfuel mixing device that allows for a high level of gas mixing with the least possible air restriction.
