Mazda is touting similar tech here running the two-stroke on compression ignition under light-load conditions (cruising at constant speed, etc. ), with the valvetrain retarded to provide 120 ...

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight ...

Two power strokes and two compression strokes per cycle. Generally, the biggest difference between a typical 4-stroke engine and the 6-stroke design is in the cam and valve timing.

"This two-stroke engine could solve these practical difficulties and simultaneously permits a much larger range of compression ratio adjustment," added the official.

EcoMotors International, a startup based in Troy, Michigan, has a new approach to an old idea–the two-stroke engine–which it says is up to 50 percent more efficient than most vehicle engines ...

How hard could it to be to build a two-stroke internal combustion engine (ICE) from scratch? This is a challenge that [Camden Bowen] gladly set for himself, while foregoing such obvious wastes of t… ...

Somehow, it still produces 120 horsepower with just half a liter of displacement, thanks to what the company calls a single-stroke combustion cycle. Perfect to throw into a Miata, as it turns out .

Is this high-revving, two-stroke, flex-fuel, 106-pound, 173-horsepower, parallel-twin engine really all it’s cut out to be?

This New Two-Stroke Engine Design Could Help Keep Internal Combustion Around Longer Engines using "entry ignition" could be up to 14 percent more efficient than a traditional internal combustion ...

RVLM vascular compression may cause significant variability in blood pressure during acute ischemic stroke by sympathetic nerve activation. 14 However, to our knowledge, it remains unclear whether ...
