Product Working Principle
As the core power conversion component of Doosan DE12 diesel engine, the DE12 engine crankshaft cooperates with engine pistons and connecting rods to complete power conversion and output. During engine operation, the high-pressure gas generated by cylinder combustion pushes the piston to perform linear reciprocating motion. Through the connecting rod transmission, the linear mechanical force is converted into rotating torque by the crankshaft. The crankshaft drives the engine flywheel and auxiliary accessories to rotate stably, realizing continuous power output of the diesel engine. Relying on high structural rigidity and dynamic balance performance, it offsets torsional vibration and inertial impact during high-speed operation, ensures stable engine speed, uniform power output, and effectively avoids power jitter, abnormal noise and mechanical failure caused by crankshaft deformation and wear.
