Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the compression ratio affect the engine?

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an engine's fuel efficiency?

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

NYK will install a variable compression ratio system (VCR system) on two large LNG-fueled coal carriers to be built at Oshima Shipbuilding. The vessels are scheduled to be delivered by the end of 2025 ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...

In its purest form, an engine is nothing more than an air pump; it takes in air and then returns it, although in a slightly modified form. Maximizing an engine's ability to process air will also ...

Despite its critics and moves toward electrification, the internal combustion engine is not yet dead. Though its design for passenger vehicles may have begun to reach its apex with Mazda’s Skyactiv ...

Compressed air isn’t really a practical form of energy storage for headline uses like transport or heating, but it’s a fun thing to tinker with at the small scale. [Tom Stanton] is plenty experienced ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That’s why it’s imperative to know whether your engine’s ...

Got an old air conditioning compressor lying around? And some engineering skills? Why not turn that thing into a real, working internal combustion engine? That's what one YouTuber did, and the result ...
