One of the most significant contributions in the history of propulsion technology came from a 19th-century engineer named Rudolf Diesel. While his idea was patented in the 1890s, it wouldn't be until ...

An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally rotating piston and sleeve arrangement, making it lighter, simpler and more ...

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 ...

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 ...

It looks like GM is working on modernising two-stroke engines by tackling their emissions problem. This could open a whole new chapter for internal combustion.

Reports of the death of the internal combustion engine have been greatly exaggerated. In the wake of stalled consumer demand and stubbornly high costs, automakers around the world are furiously ...

Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal combustion engines developed over the course of more than century.
