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

Researchers in Nigeria say water in diesel emulsions could significantly reduce nitrogen oxides and particulate emissions without major engine redesign. The approach may also preserve, and sometimes ...

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 ...

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 ...

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 ...

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 ...

At the end of May, the final meeting of the "Horizon 2020" project "GasOn" with the EU Commission took place in Brussels. The aim of this EU project was the further development of gas engines for cars ...

This Modest Engine Has A Fuel Saving Secret Weapon ...

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.

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 ...

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 ...
