If you've never watched the YouTube channel Garage54, you're missing out. These inventive Russian mechanics never seem to run out of ideas when it comes to modifying cars in extreme ways. Sometimes that just means making a car completely out of logs, but this time it's a little more technical. Ever seen a four-cylinder engine with a cross-plane crank?
A conventional four-cylinder engine has a flat-plane crank, which means two crank journals face up while the other two face down, 180 degrees apart. This can be expressed as up, down, down, up. A cross-plane flour-cylinder crank is more like up, left, right, down, where all of the journals are 90 degrees apart. It's very uncommon in four-cylinder engines. The only production vehicle with this engine configuration is the Yamaha R1 motorcycle.
