ABSTRACT
The broader impact/ commercial potential of this Small Business Innovation Research (SBIR) project includes reducing emission of Diesel engines' toxic nitrogen oxides (NOx) in challengingly low temperature exhaust operations, while eliminating damaging urea deposits saving warranty costs for vehicle manufacturers, saving fuel, reducing greenhouse gases CO2 and N2O as well as particulate matter, while potentially enabling downsizing the complex and costly diesel emission control systems. The novel technology developed in this SBIR project may be configured for retrofitting existing diesel platforms. Nitrogen oxides pose risks to human respiratory and pulmonary systems, are associated with forming ground level ozone, photochemical oxidants, acid rain and fine particles, amongst a variety of their detriments, and their emission is therefore regulated. Our concept, when successful, will therefore make available a broad value proposition to the society, the environment and to the mobility industry. Finally, the insights developed into its gas phase reactions may have applications in other branches of science and technology.
This SBIR Phase II project proposes to resolve a currently unmet need in mitigating emission of toxic nitrogen oxides (NOx) from diesel engines, especially in low exhaust temperatures such as when the vehicle operates in stop-and-go, in local delivery or when idles its engine. The goal of this project is to develop a low cost, easy-to-fit and simple-to-integrate novel technology enabling low temperature Diesel NOx reduction. Continuing our successful Phase I research results, in this Phase II project more advanced prototypes will be developed and tested in low-temperature exhaust conditions, demonstrating rapid reduction of NOx on a commercially-available Selective Catalytic Reduction (SCR) catalyst, while evaluating the impact on lowering greenhouse gases CO2 and N2O. High fidelity computer simulations will be heavily utilized to further our understanding of underlying mechanisms such as the gas-phase reactions as well as to accelerate the development path. The project outcome is expected to alleviate a remaining challenge in Diesel emission control and to be rapidly welcome by the Diesel engine and vehicle industry.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

PROJECT OUTCOMES REPORT

Diesel engines are popular due to their outstanding efficiency, great fuel economy and producing substantial torque. They are therefore highly popular in the transportation industry. However, while burning fossil fuel, Diesel engines also produce nitrogen oxides (NO and NO2, collectively known as NOx), harmful to pulmonary systems. NOx is also a precursor to ground-level ozone formation, amongst its other detriments. As such, Diesel NOx emission is heavily regulated around the world, especially in North America, Europe, China, Japan, Korea, India, and South America.
Modern emission control systems installed on Diesel vehicles are sophisticated and include four different catalyst technologies and work with remarkable efficiency. That said, like most other catalytic systems, they need exhaust heat (produced during fuel combustion) to operate. Exhaust temperature is, however, not hot enough when a Diesel vehicle operates in low-speed, low-load conditions (such as in city driving), yielding low-temperature exhaust. As a result, the catalytic system is not sufficiently efficient.
In this NSF funded project, we invented a new technology to be incorporated in the Diesel exhaust systems. It is capable of producing additional heat to the Diesel exhaust and its catalysts, helping produce substantial ammonia (from the standard urea injected in the Diesel exhaust, also known as Diesel Exhaust Fluid/ DEF). Our device’s heat enables the production of substantial ammonia, yielding highly efficient catalytic performance, reducing toxic Diesel NOx, particularly when the exhaust temperature lacks the heat needed for catalytic NOx reduction activities.
