Where is the Crankshaft Positioning Hole on the Roewe 550?

[DeLena]

The crankshaft positioning hole on the Roewe 550 is located next to the crankshaft position sensor and the crankshaft pulley. The crankshaft is the most critical component in the engine, bearing the force transmitted by the connecting rod and converting it into torque, which is then output through the crankshaft to drive the engine's accessories. Below is relevant information: 1. Crankshaft: The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertia forces, and reciprocating inertia forces, causing it to endure bending and torsional loads. Therefore, the crankshaft must have sufficient strength and stiffness, with wear-resistant journal surfaces, uniform operation, and good balance. 2. Crankshaft Journals: To reduce the mass of the crankshaft and the centrifugal force generated during operation, crankshaft journals are often hollow. Oil holes are drilled on each journal surface to allow oil to flow in or out for lubricating the journal surfaces. To minimize stress concentration, transition arcs are used at the connections between the main journals, crankpins, and crank arms. The crankshaft counterweights (also known as balance weights) function to balance the rotating centrifugal forces and their moments, and sometimes also to balance reciprocating inertia forces and their moments.
