Russian parallel four-cylinder dual crankshaft engine

Russian Monster: 4-Cylinder Dual-Crankshaft Parallel Engine 3D Model, with Internal Structure, SolidWorks 2012 Document Share. Most dual-crankshaft engines remain in patent drawings, with very few practical installations, and only some supercars are actually equipped with W16-type dual-crankshaft engines. The main issues with dual-crankshaft engines are their complex structure, large size, and difficulties with operational stability and power output. Let's examine this unique design by a Russian. A piston connects to two connecting rods, driving two counter-rotating crankshafts in parallel. By using a pair of bevel gears, the power output and stability issues are resolved. The power of a single cylinder is also increased, although the complexity remains high. There's a small simulation video included, where it runs like four little octopuses jumping around, very charming! In the end, one must admire the creativity of the Russians.
