DynaDuaLPG: A dynamically adjusting retrofit dual-fuel bio-lpg dosing system for heavy duty non-road constant rpm engines including IoT device, sensors and algorithms.

A diesel generator on a construction site or irrigation pump will soon be able to run on a mix of diesel and liquefied petroleum gas (LPG), with the blend automatically adjusted second-by-second to cut emissions without stalling. This matters because thousands of heavy-duty, non-road engines—in tractors, excavators, generators, and water pumps—run at constant speed for hours, often in remote areas where replacing them with electric or new low-emission models is impractical or too expensive. Retrofitting them with a dual-fuel system that can dynamically adjust the gas-to-diesel ratio based on load and operating conditions could slash particulate matter and nitrogen oxide emissions without requiring a full engine replacement. If successful, the DynaDuaLPG system—which includes an Internet-of-Things device, sensors, and control algorithms—could be fitted to existing engines at a fraction of the cost of buying new equipment. The impact would be felt quietly across supply chains: lower emissions from the pumps that irrigate fields, the generators that power remote telecom towers, and the machinery that builds roads and houses. The project is applied engineering, not fundamental science; its value lies in immediate, practical deployment.
