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 ...

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 ...

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 ...

Hybrids vehicles are great alternatives to traditional vehicles, but since they still use conventional fuel, they contribute ...

How engine design has evolved to boost fuel efficiency, and where it's going from here.

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 ...

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 ...

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 ...

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 ...

In comparing the GE9X and Trent XWB, it becomes clear that while both engines share common goals of efficiency, reliability, ...

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 ...

The engine in your car right now is terrible at its job. The concept of adiabatic is as old as automotive engineering (BTW it’s pronounced “aid-ee-a-bad-ik”), and simply means a system where heat ...
