Is Replacing the Four-Matching Set the Same as a New Car?
2 Answers
Replacing the four-matching set is not exactly the same as a new car, but the difference is minimal. Below is an introduction to the engine four-piece set: 1. Introduction: The engine four-piece set typically refers to the cylinder liner, piston, piston rings, and connecting rod pin. 2. Moving Parts: The main moving parts inside the engine are the crankshaft, piston, and connecting rod. It consists of components such as the crankshaft, piston, piston rings, piston pin, connecting rod, and flywheel. The crankshaft is a shaft with several bends. The number of crank throws depends on how many cylinders the engine has and their arrangement; one connecting rod connects to one crank throw, so the number of crank throws equals the number of cylinders; two connecting rods connect to one crank throw, making the number of crank throws half the number of cylinders.
I just replaced the four-piece set (piston, piston rings, connecting rod, and cylinder liner) on my old car, and honestly, the feeling is quite nuanced. It definitely has more power than before the overhaul, idles without shaking, and the oil burning issue is mostly gone – it drives noticeably smoother. But saying it's exactly like a brand-new car would be a bit idealistic. Think about it: other parts of the car have already clocked over 100,000 kilometers, and aging is inevitable. The newly replaced four-piece set operates within the old engine block framework – the running-in condition and assembly precision, even with a master technician's skills, can hardly 100% replicate the factory's original state. However, with reliable parts and proper repairs, restoring it to about 80-90% of a new car's performance is still achievable.
