WebJul 18, 2024 · A flat-plane crank engine is basically an engine where the crankshaft’s counterweights are alternating each other in a 180-degree angle. Further, the crank has multiple journal bearings: ones where the connecting rod sits, others that sit on the engine’s block. The counterweights are set between the connecting rod bearings, on each side of ... WebDec 19, 2024 · The primary difference between these two crankshafts is the degree their pistons move in relation to the crankshaft.
