The Development of the New Type Crankshaft in the V6 Engine 990051
Today, NVH characteristics are vital to satisfying the demands of modern internal combustion engine. For this purpose, forged crankshaft has been applied unexceptionally to engine instead of cast crankshaft. So, Hyundai Motor Company (HMC) developed new forged crankshaft to improve NVH characteristics in the new V6 engine. But, Forged V6 crankshaft has limitation of cosmetic form because of complexity of its die parting line. HMC's new forged V6 crankshaft with 6-counterweights was developed through optimized design for low cost, high stiffness, easy productibility and compact size. This new crankshaft acquired the patent in many countries.
