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 ...

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

Thermo King data shows APUs cut idle fuel use by up to 75% and reduce engine wear while supporting driver comfort and compliance.

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 ...

Every fleet strives to achieve two things when it comes to engines. The first is to maintain efficiency in order to reduce operating and service costs. The other is to ensure the longest possible ...

Pratt & Whitney thinks the aerospace industry might need a bit more time to achieve a broad goal of squeezing at least 20% more efficiency out of the next generation of narrowbody aircraft engines.

The days of internal combustion engines are numbered. Unfortunately, the exact number is constantly shifting, with regulators moving the goalposts so often that manufacturers are left scrambling to ...

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 ...

There's more to piston shapes than you might think. Whether it's domed, flat, or dished, all pistons have their fair share of pros and cons when it comes to performance and efficiency. Understand that ...

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 ...

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 ...
