Engineers develop Next-gen Clean Engine Technology


In a recent development, engineers at the Southwest Research Institute have developed the next-generation of clean diesel engine technology. This is to reduce emissions of hazardous nitrogen oxides and carbon dioxide while reducing fuel consumption.

Engineers at Southwest Research Institute worked with regulatory agencies as well as vehicle manufacturers and suppliers. This is to combine engine modifications with integrated after treatment technology and control strategies to reach near-zero emissions levels. Engineers at Southwest Research Institute developed the technology for California Air Resources Board – a state agency charged with combatting air pollution.

“The continued efforts of a multi-disciplinary team has led to the development of one of the most fuel-efficient, low- emission diesel engines in the world,” stated engineer at Southwest Research Institute who is a member of the low nitrogen oxides team.

Technology to aid address Effects of Nitrogen Oxides

Meanwhile, the technology developed to address California’s pollution challenges, the technology could serve to be solution for communities struggling with effects of nitrogen oxides.

The Environmental Protection Agency states nitrogen oxides are harmful to the environment and human health. In 2024, the State of California plans to put in place tighter emission standards and will require that heavy-duty engines generate less pollutants.

The research team at Southwest Research Institute adopted a systems approach to address the problem. For this, the team satisfied California Air Resources Board’s stringent to reduce nitrogen oxides by 90 percent. And lower carbon dioxide emissions at the same time.

“The low nitrogen oxides technology developed by researchers at Southwest Research Institute is a significant step forward in improving heavy-duty engines and lower greenhouse gas emissions,” said vehicle program specialist at California Air Resources Board. Such solutions to simultaneously address nitrogen oxides and greenhouse gas emissions are key to develop sustainable heavy-duty transportation and meet public health obligations.
