The piston connecting rod assembly mainly consists of the piston, piston rings, piston pin, connecting rod, and connecting rod bearing. The piston connecting rod assembly converts the reciprocating motion of the piston into the rotational motion of the crankshaft, while transforming the force acting on the piston into the torque output by the crankshaft to drive the vehicle's wheels. It serves as the transmission component of the engine, transmitting the pressure of the combustion gases to the crankshaft, causing the crankshaft to rotate and output power. Precautions for using the piston connecting rod assembly include: 1. Check the directionality of the piston and connecting rod before assembly; 2. Use special tools or heat to 60 degrees when installing the piston pin; 3. Pay attention to the cylinder markings when disassembling and installing the piston, and make marks if there are no existing markings.

What is the Safe Following Distance on Highways?

Highway safe following distance varies depending on the situation: 1. When the speed exceeds 100 kilometers per hour, a distance of more than 100 meters should be maintained from the vehicle in front in the same lane; 2. When the speed is below 100 kilometers per hour, the distance from the vehicle in front in the same lane can be appropriately reduced, but should not be less than 50 meters. Precautions for driving on highways include: 1. Both the driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid sudden steering wheel movements while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle in front, the turn signal must be activated in advance; 4. Only adjacent lanes are allowed for overtaking, and the vehicle should immediately return to the driving lane after overtaking. Vehicles must not ride or drive on the lane dividing line; 5. Do not reverse, drive in the opposite direction, cross the central divider to make a U-turn or turn, conduct test drives, drive training vehicles, or overtake or park on ramps.

What is the actual lifespan of a CVT transmission?

CVT transmission has an actual lifespan of approximately 400,000 kilometers. CVT transmissions can achieve continuously variable transmission over a wide range, providing optimal matching between the drivetrain and engine conditions. By relying on the transmission's continuously variable speed adjustment to adapt to various vehicle speeds, the engine can operate under favorable conditions for extended periods, improving combustion efficiency and correspondingly enhancing fuel economy. The functions of the transmission are: 1. To change the transmission ratio to meet the traction needs under different driving conditions; 2. To enable reverse driving; 3. To interrupt the power transmission to the drive wheels during engine startup, idling, and gear shifting.
