Integration of low-pressure hydrogen storage cylinder and automatic controller for carbon deposit removal in car engine

This study has completed the preliminary test of the “automotive hydrogen gas release controller with low pressure hydrogen storage module” in the carbon removal of cars engine, this product has integrated (1) a low pressure hydrogen storage cylinder (metal hydride) and (2) a solenoid valve controller with flow meter. Under normal temperature and pressure settings, this system is able to transfer hydrogen gas to the vehicle's intake air system and mixing with the air, entering the engine chamber. The solenoid valve controller and flow meter can control the optimized hydrogen gas output flow rate, activating the carbon deposit removal. The results of this study show that in the example for a 1,600 cc vehicle, 1690 USD may be saved for gasoline in a year with reducing 164.8 ton of CO2 emission (The enhancing of fuel utilization 11.6%). For a 2,000 cc vehicle, 3070 USD may be saved for gasoline in a year with reducing 291 ton of CO2 emission (The enhancing of fuel utilization 20.6%). A set of low pressure hydrogen storage system has been developed in this research, it is safe and convenient for consumers, the Solenoid Valve Controller and Flow meter allows for optimized use of hydrogen gas, reducing the waste of excess hydrogen gas.
