A method which improves the combustion efficiency of fuel in the internal combustion engine is disclosed. The method is substantially characterized in that a small amount of ammonia gas is incorporated into the hydrocarbon fuel in any position between an air intake port and an intake manifold of the engine. Due to the above addition of ammonia, the combustion of the hydro-carbon fuel in the combustion chamber is enhanced with the improved composition of the discharged gas.

A device for improving the combustion efficiency of hydrocarbon fuel in an internal combustion engine of a motor vehicle comprising: an airtight container containing a solid ammonium compound which is capable of producing ammonia gas, an ammonia gas flow-out passage having one end disposed in said container for conducting ammonia gas from said container, a conducting flow passage having an intermediate portion communicating with said ammonia gas flow-out passage, said conducting flow passage having its downstream end connected with a fuel stream of said internal combustion engine by means of a heat-resistant tube, said heat-resistant tube has one end joined to a circular tube which has a plurality of equidistant openings open to the inside of an air cleaner of said internal combustion engine, said conducting flow passage having its upstream end open to atmosphere to receive on-coming air as the motor vehicle moves forwardly, an air introduction conduit leading to said container, said air introduction conduit having its upstream end open to atmosphere to receive on-coming air as the motor vehicle moves forwardly, whereby the air in said air introduction conduit flows to said container to increase the air pressure within said container in proportion to the forward moving speed of the motor vehicle resulting in air movement within the container promoting the production of ammonia gas from said solid ammonium compound, and venturi means at said intermediate portion of said conduction flow passage, said venturi means receiving said on-coming flow of air to induce flow of ammonia gas from said container into said conducting flow passage and thence to said fuel stream.
