A team of students from the University of California’s Riverside Bourns College of Engineering recently developed a simple-yet-brilliant device that can make lawnmowers greener. The team’s NOx-Out system is an innovative device that reduces emissions, noise, and the smell of gasoline from lawnmowers. The 6-inch-long device includes a filter, a glass jar that holds two ounces of urea solution, and a lawnmower muffler, and it works by capturing particulate matter in a glass quartz filter and then spraying an ultra-fine solution into the exhaust system. The team recently won first place at the WERC: A Consortium for Environmental Education and Technology Development Competition in Las Cruces for the device.
