A Low-Cost Automatic DEF Refueling Controller for Diesel Generators
摘要
This paper presents a design and implementation of a low-cost automatic controller for Diesel Exhaust Fluid (DEF) tanks. The controller monitors error codes from the generator’s Engine Control Unit (ECU) and readings from a temperature and level sensors and refuels the generator’s DEF tank when needed. The proposed controller presents a low-cost and easy to install solution for DEF refueling automation; eliminating cumbersome refueling process that requires constant user monitoring.
