The lower the BSFC, the more efficient an engine is. In this video we'll define brake specific fuel consumption, show how it correlates with efficiency, look at a BSFC map, compare BSFC with RPM, ...

A key enabler is the newly redesigned aftertreatment system, which uses trusted components in a smarter and more efficient ...

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 ...

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

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 ...

The Rolls-Royce Trent XWB-84 EP boasts strong operational credentials.

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.

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 ...

Kyle Hyatt (he/him/his) hails originally from the Pacific Northwest, but has long called Los Angeles home. He's had a lifelong obsession with cars and motorcycles (both old and new). One of the cool ...

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 ...

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 ...

A schematic illustration of the biochemical heat engine model that achieves maximum power while approaching Carnot efficiency. The left panel shows the two-state engine, where the higher energy state ...
