Engine Emissions Reach All-Time Low
Propane autogas engines have hit an all-time low. But as opposed to the stock market, that’s a good thing. Recently, new technology has enabled propane engines to reach near-zero emissions. Here’s the latest in low-NOx engines and how they can work for your company. All engines of any fuel type must be certified to the Environmental Protection Agency’s standard to control vehicle emissions. Over the years, the EPA has set tougher emissions standards on nitrogen oxides, known as NOx. According to a recent study, diesel-fueled medium- and heavy-duty vehicles are the number one source of NOx emissions in almost every single metropolitan region in the US. Approximately 55 percent of man-made NOx emissions comes from motor vehicles.
