Conventional methods to measure gas concentrations and, in particular, NO are typically based on sampling by valve, sample treatment and subsequent analysis. These methods suffer low spatial and ...

Diesel and gasoline fuel sources both bring unique assets and liabilities to powering internal combustion engines. But what if an engine could be programmed to harvest the best properties of both fuel ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Researchers use Direct Numerical Simulations to enhance efficiency, reduce pollution in diesel engines. A "cool flame" may sound contradictory, but it's an important element of diesel combustion -- ...

Despite sounding like a thoroughly entertaining evening out, it is actually a description for one of the most important processes in the majority of engines. Known as the four-cycle, it is the process ...

If diesel engines need air for combustion, then how can submarines use them? Here's what you need to know about the clever engineering behind diesel subs.

In 1673, Christian Huygens invented the first engine. It was designed to pump water from the Seine River to King Louis XIV's Palace of Versailles. Built with an open combustion chamber, it consumed ...
