Porsche's new patented six stroke engine might not be a thing of reality yet, but the new technology is still very ...

What’s the voodoo behind the horizontally opposed cylinder setup only found in Subarus and Porsches? And what sets them apart ...

Besides the fact that there are no fuel-air explosions involved, these pistons are also double-acting ... tilting back and forth as the crankshaft rotates. After some testing, he discovered ...

Then it's placed inside the piston and the pin connects the two components. Now, the engine can finally be assembled. First, the crankshaft is bolted onto the block. Then the piston is pushed into ...

If you’re familiar with engine cycles, you know that engines displace air by means of a crankshaft-driven piston. It draws air in on the intake stroke and pushes it out on the exhaust stroke.

General Motors is scrambling to rectify the engine failures for its 6.2-liter V8 truck engine – one of which bit the dust after only 4 miles.

Basically, two opposed pistons are rigidly connected to a perpendicular slot. Now picture a crankshaft pin engaging a slider that rides up and down in that slot as the pistons shuttle back and forth.
