The U.S. Environmental Protection Agency (EPA) is using ANSYS simulation solutions to model in-cylinder combustion and develop an advanced test engine that will have fuel-saving and emissions-reducing technologies. The engine will include modifications to combustion chamber geometries, fuel injection strategies, fuel composition, valve timing and intake conditions.
Using ANSYS FORTE, the EPA can experiment with engine design and inexpensively make multiple design iterations. With the software, the government agency also plans to use ANSYS’ soot modeling capabilities as well as gain a greater knowledge of combustion dynamics through computational fluid dynamics (CFD) modeling.
“The goal of our Clean Automotive Technology program is to research, evaluate and develop advanced engine and drivetrain technologies that help increase fuel efficiency, reduce regulated criteria emissions such as nitrogen oxides and particulate matter, and cut greenhouse gas emissions,” said Matthew Spears, Heavy-Duty Onroad and Nonroad Center Director of EPA’s Office of Transportation and Air Quality. “Using ANSYS solutions to generate realistic 3-D simulations of internal combustion engines, we can gain visibility into critical engine behaviors in a timely, cost-effective manner and obtain accurate and predictive results to guide the development of our test engine.”
