Diesel engines use compression to ignite the fuel, which needs to have an even burn, and cetane boosters have an important ...

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 ...

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 ...

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 ...

Diesel and gasoline engines might look alike under the hood, but they use oil in very different ways. Gas engines run cleaner, but diesels create much more soot, crank out higher compression forces, ...

We are at a critical time and supporting science journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen scientific ...

Engineers are struggling to make the combustion engine run purely on hydrogen, but scientists believe there is an easier way. Engineers at the University of New South Wales (UNSW) in Sydney have ...

Proper cooling is critical to any engine. Without some way to remove the heat created during the combustion process, the engine will quickly become a lump of scrap metal. But today's coolants provide ...

Diesel engines are considered more polluting than their petrol counterparts. This is the key reason why the small cars in India have been shying away from using diesel engines, in face of the mounting ...
