Components of the Crank Connecting Rod?

[LaEvan]

The crank connecting rod mechanism consists of three parts: the engine block group, the piston connecting rod group, and the crankshaft flywheel group. More information about the crank connecting rod mechanism is as follows: 1. The crank connecting rod mechanism operates under conditions of high temperature, high pressure, high speed, and chemical corrosion. When the engine is working, the maximum temperature inside the cylinder can exceed 2500K, and the maximum pressure can reach 5~9MPa. When the car engine speed is between 3000~6000r/min, the piston completes 100~200 strokes per second. 2. The front end of the crankshaft in the crank connecting rod mechanism is mainly used to drive auxiliary mechanisms such as the valve train, water pump, and fan. The front end shaft is equipped with a timing gear, belt pulleys for the fan and water pump, a torsional vibration damper, and a starter claw.

As a guy who spends all year in the workshop, I know the crankshaft-connecting rod mechanism inside out. That thing mainly consists of three parts: the piston, connecting rod, and crankshaft. The piston moves up and down in the cylinder, with rings on its surface to seal the combustion chamber; one end of the connecting rod is attached to the piston via the piston pin, while the other end connects to the crankshaft; the crankshaft is basically a big shaft with multiple bends, responsible for converting the piston's linear motion into rotational force for the wheels. I've dealt with plenty of engine issues, like carbon buildup jamming the piston rings, connecting rod deformation, or bearing wear—any of these can cause engine misfires or shaking. During regular maintenance, it's advisable to check the oil quality and prevent the engine from overheating, otherwise, parts wear out faster and lifespan drops significantly. If an experienced driver hears unusual engine noises, it's best to get it checked by a professional shop immediately—don't delay. Once these small parts fail, the whole engine could be done for.
