The German automaker sees your four-stroke engine and raises you... two more strokes. Ready for some math? Porsche just patented an engine design titled: "Method for a Combustion Machine With Two ...

Since the crankshaft's rotation moves other crucial components, this process powers vehicles and other devices that house the engine, but it is also the main difference between two-stroke and four ...

And that’s how this “six-stroke” engine achieves power pulses in ... speed ratio of the planet wheel relative to the crankshaft should be two to three. In case that crankshaft setup sounded ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft ... We’re introduced to the traditional two-stroke diesel engine as thermally efficient but ...

with oil in the crank case so that the poor engine wasn’t running dry any more. With a 40:1 fuel/oil mixture the little engine idles and runs as well as a two-stroke can, belching blue smoke and ...

Every internal combustion engine has to complete two missions— set ... in the form of exhaust. Each stroke pushes or pulls a piston attached to a crankshaft, sending power through the ...

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 ...

Unlike a four-stroke engine, which musters a single power stroke for every two revolutions of the crankshaft, Porsche's six-stroke affords two power strokes for every three turns of the crank.

A 4-stroke engine requires four of these movements (or two rotations of the crankshaft) to complete a power cycle in which air and fuel are drawn into the combustion chamber, compressed ...

Every 4-stroke engine ever made – about 80% of ... within a ring on planetary gears, meaning as the crankshaft rotates, the pistons have two entirely different top-dead-center positions as ...
