The BGTC Solution
The BGTC solution is one of both simplicity and complexity. Simplicity because it uses the algorithms of the Original Equipment Manufacturer (OEM). Complexity in that to maximize the efficiency of substituting fuels with varying energy content and air burn ratios, the system must be flexible through a wide range of the engine performance and vehicle speed curves. Through collection, analysis and use of the OEM engine control management(ECM) data and vehicle chassis data, the SEECM can effectively and sequentially port inject lower energy gaseous less costly fuels without loss of power or speed -

The Technology
There are basically two types of aftermarket alternative fuel systems installed on diesel engines. Fumigation which is a single point or multi-point injection system or sequential port injection system. BGTC’s sequential port injection system is an individual sequentially port injection system with a gaseous injector for each engine cylinder. Since not all cylinders receive the same energy volume of fuel at the same time, it is imperative for the engine to receive the correct energy volume of both alternative gaseous fuel and diesel fuel. The alternative gaseous fuel must fulfill the criteria of: equaling the total energy content established by the manufacture based upon available air, maximum substation of diesel fuel without effecting power, speed or exhaust emissions.
The BGTC "Precision Twin Fuel" system is a Sequential Port Injection (SPI) type system with adaptive capability to operate on a wide range of engine year models with similar fuel systems and alternative fuel types without extensive reprogramming or hardware changes.
The BGTC "Precision Twin Fuel" system gathers data from the engine ECM to determine the fuel volume that is required per combustion event. The chassis data ECM provides data concerning the operational mode of the vehicle. That data tells the BGTC computer if the vehicle is accelerating, slowing, going downhill, going uphill, etc. along with road speed, gear selection, data which ultimately allows the BGTC computer to determine the fuel energy content required for the next combustion event and allow an optimum blend of diesel fuel with the alternative gaseous fuel.
This concept has been proven by the operation of a system installed on a major Midwest Fleet Transportation Navistar 9600 series truck with a Cummins ISX 15 liter diesel engine. The test system has been in operation for the past three (3) years. The system was installed in Dec 2012 with CNG tank installation completed March 2013 and put into operation using compressed natural gas alternative fuel and the original diesel fuel used for ignition. This truck has consistently averaged between 55% and 65% substitution of the diesel fuel during this test period.
System Attributes
Easily installed; capable of adapting to similar engine fuel systems without extensive reprogramming; can fit all major manufacturers’ engines without extensive R&D; 24 month or less total system ROI from fuel savings (approx.. 10,000 gallons of diesel displaced per truck per year based on 120,000 miles driven per year). Allows for negotiation of long term gaseous fuel supply contracts (in many cases up to five (5) years). Can be adapted to engines in a multitude of applications.
