The original concept of combustion engines as we understand them dates as far back as the late 1800s. And while they are more or less a solved science today, they definitely didn't start that way.

Depending on the type of electric motor setup, hybrids use several interesting ways to charge and recover battery power while ...

Combustion efficiency in internal combustion engines refers to the proportion of chemical energy in the fuel that is converted into useful mechanical work. Attaining high combustion efficiency is ...

In case you missed it, the automotive industry has been on a steady trajectory of internal combustion engine (ICE) downsizing for years. Battery-powered electric vehicles may capture most of the ...

Turbocharger use is more prolific than ever, and understanding how one works explains why it’s such a popular choice. To understand the benefit of a turbo, we need a refresher on the basics of the ...

There are several types of engine compression testers. Be sure to use the correct type for your specific engine, otherwise you may get an inaccurate reading.

A new study published in Engineering has explored a pilot-ignition reactivity-stratification (PIRS) combustion strategy for ammonia-fueled compression ignition engines, realizing a high ammonia energy ...

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...
