Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the ...

Automakers like Toyota, Mercedes, and Mazda are ditching V6 engines in favor of more efficient and cost-effective powertrains ...

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 ...

There’s no doubt that EVs and hybrids can deliver better fuel economy than traditional gas-powered vehicles. But that ...

Detroit Gen 6 engines target improved fuel efficiency and familiar service architecture, while being compliant with upcoming emissions rules.

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions ...

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 ...

While a lot of automotive engines have one spark plug per cylinder, the HEMI V8 might have two per cylinder. What is the science behind that?

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 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 ...

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 ...
