Abstract—Fuel optimization plays a vital role all over the world. In this work, there are three major faces: The first face is designing HHO generator assembly which is related to mechanical designs and second face is designing a circuit board for Pressure sensor, Temperature sensor, and Oxygen sensor and its overall electrification, plumping works with gas tight protection, and also designing electronics circuits for different sensors to interface with FPGA the third face is designing electrolytic process control using a System on Chip as a Core in VHDL and implementing in FPGA. This Core monitors the HHO generator with sensors and its accessories continuously measuring the vehicle engine performance. From this design the fuel utility is reduced from 15% to 30% which minimizes the carbon deposition in the cylinder thereby increasing the changing period of engine oil, it also improves the efficiency of the engine and the life span. Engine torque also increased and pollution gets reduced to maintaining the green house effect. Overall the cost of the product is very low
