Direct numerical simulations let researchers improve combustion efficiency and lower pollution in diesel engines. “Cool flames” may sound contradictory, but they could lead to better engine designs ...

Cold fusion, despite probably being impossible, is a good idea. Take a process known to create a meaningful amount of power and remove the harmful byproducts (like explosions), and you've got a winner ...

Diesel engines are widely used in agricultural machinery, vehicles, and ships because of their high thermal efficiency. The sulfur contained in the diesel fuel is oxidized to sulfur dioxide by ...

The diesel engine was one of the most ambitious engineering undertakings in history. It was so radical and high-minded that it still hasn’t been totally perfected—even after 150 years of development.
