The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

As we begin the last article in this series on the basics of the internal combustion engine, let's stop to review what we've covered during the last five articles. We began last May by detailIing the ...

If you’re shopping for a new fishing boat or an outboard motor to power it, one of the decisions you’ll have to make is between a 2 stroke vs 4 stroke engine. Unless you’re going electric, this choice ...

Years ago, the choice was clear: When it came to 2 stroke vs 4 stroke outboard motors, 2 stroke won every time. Two stroke motors offered a better power-to-weight ratio, were cheaper to manufacture, ...

Researchers aim to meld the best attributes of both the power-dense two-stroke and the vastly cleaner four-stroke engines. I can never resist a good oddball engine, and this one’s pedigree is ...

It is quite ironic that internal combustion engines (ICEs) have remained basically the same for more than one hundred years. It is only now – when they are allegedly on the verge of disappearing – ...

Anyone who appreciates simplicity of design and efficiency of operation has to like small two-stroke-cycle engines that power construction tools such as cut-off saws, rammers and breakers. Producing ...

Porsche was issued a patent for its six-stroke combustion engine on October 22, 2024. The company describes the new engine as having a "working cycle" of three complete crankshaft revolutions with two ...

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 ...
