Because internal combustion engines operate under such high pressures, it's tough to get their inner workings on camera. Usually the whole process is shrouded by thick metals to contain all of that ...

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

There are many differences between diesel and gas engines, including some less obvious aspects of engine construction, such ...

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.

High frequency combustion instability is a very challenging subject 1. Once the high frequency combustion instability occurs, the dramatically increased heat flow on the combustor wall causes the ...

The rocket-based combined-cycle (RBCC) engine is regarded as one of the most viable propulsion systems for single-stage-to-orbit launch vehicles. Because of the relatively low total temperature of the ...

Rotary engines have an aura of cool. In games of Top Trumps, the V12 might have been king, but a rotary was a joker, a wild card. A lack of mainstream success no doubt contributes; there are reasons ...

Automakers once bet big on bizarre ideas—from swirling airflows to variable compression—and the results were as fascinating as they were short-lived. Automotive engineers have invested countless ...

With oil reserves projected to exhaust by 2040 and mounting climate concerns, the automotive industry faces an urgent need for alternative fuel sources. Companies like Toyota and Honda have championed ...
