Engineers design modern engines to run in a narrow temperature window where power, efficiency, and emissions all line up. The ...

As we begin the last article in this series on the basics of the internal combustion engine, let's stop to review what we've covered during the last five articles. We began last May by detailIing the ...

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 ...

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.

Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

Internal combustion might as well be wizardry to me. I have a basic idea of how engines work and I’ve been wrenching on them since I was a teenager, so I get the gist of it, but my feeble brain still ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...

Modern engines can be incredibly complex but even classic V8s have more moving pieces than most realize. This fully transparent engine with an oil pump and lighting to signify combustion demonstrates ...
