He has made significant contributions to the field of engineering, particularly in the areas of combustion emission reduction and drilling methods. With a total of three patents to his name, Jacobson's work reflects a commitment to improving efficiency and reducing environmental impact.

Latest Patents

One of Jacobson's latest patents is a combustion emission-reducing method. This innovative approach utilizes a fluid mixture composition as a fuel for engine-powered transportation vehicles. The mixture includes an ammonia-like reductant component and an ammonia-like carrier component, with the potential addition of a hydrocarbon component such as gasoline or diesel fuel. The method involves separating the mixture into two streams, where the first stream serves as fuel for the engine, while a portion of the second stream is injected into the exhaust gases to reduce NOx emissions. This technique also aims to enhance fuel efficiency by using a lean air/fuel ratio.

Another significant patent is the underbalance jet pump drilling method. This method provides a unique approach to rotary drilling by maintaining an underbalanced drilling fluid pressure at the drilling face while ensuring overbalanced pressure in the wellbore. The method employs a rotary drill within a housing that contains a jet pump, which effectively draws and pressurizes the cuttings and drilling fluid. This innovative technique helps avoid overpressure strengthening of the drill face and underpressure damage to the wellbore.
