Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines slightly above 40%. This inefficiency stems from the equal length of all four ...

In this video, we examine the functioning of four-stroke and two-stroke engines, highlighting their differences along with ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...

When I went to school for engine repair in the 1980s, we studied the differences between two- and four-stroke engine cycles extensively. If you're not familiar with engine strokes, understanding the ...

There are three fathers of invention when it comes to nearly every car on the road today: Otto, Diesel, and Atkinson. They all had one thing in common—a drive to improve the efficiency of the engines ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...
