Modeling Autoignited Combustion to Drive Engines Forward

It’s no surprise that Rudolph Diesel became a millionaire only 6 short years after he patented the first diesel engine in 1892. When used in cars and trucks, diesel engines can deliver better fuel economy than gasoline engines and can last hundreds of thousands of miles longer. The efficiency of…

Simulating Turbulent Combustion Speeds Design of Power and Propulsion Devices

Supercomputers help optimize engines, turbines, and other technologies for clean energy High-fidelity large eddy simulation (LES) of direct-injection processes in internal-combustion engines provides an essential component for development of high-efficiency, low-emissions vehicles. Here LES reveals how fuel from a state-of-the-art injector mixes with air inside an engine cylinder. Image credit:…
