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 ...

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?

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 ...

Without getting too deep into the science behind internal combustion, a “stroke” occurs each time the pistons go up or down. In other words, a two-stroke engine completes one power cycle with every ...

In actuality, modern internal combustion engines come in two distinct varieties, spark-ignition and compression-ignition. These have several small, yet distinct differences.

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 ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now ...
