A system for managing the addition of hydrogen gas to an engine which receives a conventional fuel, wherein the supply of conventional fuel to the engine is managed by an engine control module, the system comprising: a storage means for storing the hydrogen gas; a supply line fluidly connecting the storage means to the engine; a control means having a control unit for controlling the rate of addition of the hydrogen gas from the storage means to the engine, wherein the control means is adapted to send a modified signal to the engine control module for the engine control module to supply a reduced amount of conventional fuel to the engine when the system is operating; a high pressure to low pressure regulator valve in the supply line for converting a high pressure hydrogen gas in the storage means to a lower pressure hydrogen gas, wherein the system enables a metered amount of the hydrogen gas to be delivered across a full range of manifold pressure and throttle position; and a control valve in the supply line and wherein the control unit dynamically controls the control valve to vary the rate of flow of the lower pressure hydrogen gas to the engine in response to current intake manifold pressure and throttle position of the engine.
