Timed Port Fuel Injection for EMD Engines

The T.P.F.I. System lowers operational costs, extends fuel capacity, reduces NOx, CO2, and PM emissions. The system does all this without any modification to the OEM fuel system, or internal parts of the engine. The engine still maintains it’s OEM rated horsepower, and is able to revert back to 100% diesel at the flip of a switch. View Brochure
