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 ...

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 ...

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 -- ...

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 ...

Whether it is the rush towards on-road electric vehicles or the steady stream of announcements from OEMs about their latest electric construction machinery, it can feel like the days of the diesel ...

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.
