Exhaust Stroke – Gases are expelled from the combustion chamber and released into the atmosphere. There are, of course, different types, sizes, and configurations of combustion engines, each with ...

Porsche recently revealed its patented idea for a six-stroke combustion engine. The design has potential to make internal combustion engines even more efficient, theoretically preserving the use ...

In addition to the major types of combustion engines, the system can be differentiated further by the number strokes present in the energy generation process. A "stroke," in this context, refers ...

Another issue constantly on automotive engineers' minds is pollution. Internal combustion engines burn gasoline and air, which release the results into the atmosphere, so they are a major source ...

A working DIY two-stroke in all of its glory, with the flywheel removed. (Credit: Camden Bowen) How hard could it to be to build a two-stroke internal combustion engine (ICE) from scratch?

That said, we'd certainly be excited to see a six-stroke engine up and running, especially if it keeps the internal-combustion engine alive farther into the future. Related Stories Porsche ...

At the Low net-GHG Fuel and Engine Technologies Symposium at the University of Wisconsin in June, researchers noted that the life of familiar internal combustion engines may be extended. This will ...
