A system for reducing polluting emissions of diesel engines includes a hydrogen gas generator that mixes the hydrogen gas with diesel fuel during certain operations phases of the engine. A default program mixes no hydrogen gas with the diesel fuel. A first operational program, during a cold start, mixes the hydrogen gas and diesel fuel in a 1:1 ratio. A second operational program, during a stabilization phase, mixes the hydrogen gas and diesel fuel in a 1:3 ratio. A third operational program, during a hot start phase, mixes the hydrogen gas and diesel fuel in a 1:2 ratio.

A reformer system may include a reformer device having a fuel inlet, an air inlet and a gas outlet, a first valve set coupled to the fuel inlet and configured to selectively supply a reformer fuel flow from an engine fuel flow to the fuel inlet, a second valve set coupled to the air inlet and configured to selectively supply a reformer air flow from a compressor outlet air flow to the air inlet, and a controller in electrical communication with the first valve set and the second valve set. The controller may determine a target reformer fuel flow based on a target gas flow, determine a target reformer air flow based on the reformer fuel flow and a target air-to-fuel ratio, adjust the reformer fuel flow according to the target reformer fuel flow, and adjust the reformer air flow according to the target reformer air flow.
