Recent advances in the analysis of aviation engine efficiency and sustainability have expanded the understanding of engine performance beyond traditional energy metrics. Researchers are increasingly ...

Here in 2019, only the most fringe reactionaries are able to claim with a straight face that climate change is not a thing. But after years of the media doing its “two sides” thing, recalcitrant ...

Getting from A to B by most means of transport is polluting; incomplete combustion of fuels releases soot and unburned fuel into the atmosphere, along with greenhouse gases such as carbon monoxide and ...

One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...

Purdue University’s Greg Shaver doesn’t believe there should be a trade-off between protecting the air we breathe and achieving better engine efficiency of large vehicles on the road. Shaver, a ...

Built on its long-running Heavy-Duty Engine Platform, Daimler Truck North America’s new Gen 6 diesel engines utilize a novel ...

As fast as electric cars are improving and expanding, there are some things that gas engines do better—many experts agree that gasoline engines will be around for several decades. Developing electric ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

Some benefits of re-engining programs are due to the fact that newer engine models typically embody more advanced technologies and design and manufacturing processes than were available for the ...

There are something like a billion cars on the world’s roads today and almost all of them are powered by internal combustion. In fact, the 150-year-old technology is at the heart of most forms of ...

The committee has looked at a number of potential engine modifications as well as concepts for re-engining of current aircraft. In general, at 2006 fuel prices, it was difficult to recommend any ...
