The GTI Bi-Fuel System from Altronic Controls offers an affordable and efficient means ofoperating industrial diesel engines utilizing both diesel and natural gas (or other available gas) as fuel sources. This innovative, patented system, which requires no modification to the internal components of the engine, allows for operation on natural gas for up to 80% of the fuel required to maintain the desired speed and load. Reduced exhaust emissions and fuel costs are just a few of the benefits of Bi-Fuel operation.

The GTI Bi-Fuel System operates by blending both diesel fuel and natural gas in the combustion chamber. This is achieved using a fumigated gas-charge design, whereby natural gas is pre-mixed with engine intake-air and delivered to the combustion chamber via the air-intake valve. The air-gas mixture is ignited when the diesel injector sprays a reduced quantity of diesel fuel into the chamber.
This diesel "pilot" acts as the ignition source
for the primary air-gas combustible mixture.
Because the Bi-Fuel System utilizes the OEM air-intake and diesel injection systems, no internal engine modifications are required for installation.
