Zorluk: KolayEngine Principles and Internal Components

Which internal engine component connects the piston to the crankshaft to convert the piston's linear up-and-down motion into rotary motion?

  1. A
    Camshaft
  2. Connecting rodCevap
  3. C
    Rocker arm
  4. D
    Intake manifold

Cevap

Connecting rod
The connecting rod provides the physical mechanical link between the piston and the crankshaft. As combustion forces the piston downward in a linear path inside the cylinder cylinder bore, the connecting rod pivots on the wrist pin and pushes the offset crank journal, converting reciprocating motion into the rotary motion needed to drive the vehicle.

Adım Adım Çözüm

1
Identify the motion types of the piston and the crankshaft.
The piston travels in a straight line up and down inside the cylinder (reciprocating motion), while the crankshaft spins on its main bearings (rotary motion).
Internal combustion engines rely on mechanical linkages to bridge the linear expansion of burning gases into usable rotational work.
2
Determine which component links these two parts together.
The connecting rod connects to the piston via the wrist pin at its small end and to the crankshaft journal at its large end.
This structural connection allows the rod to pivot as the piston pushes downward, forcing the offset crankshaft journal to rotate.
