Valve Train
A valve train is an essential part of a car's engine that controls how air and fuel enter and exit the engine. Think of it like the breathing system of the engine. It includes several connected parts (valves, springs, lifters, and camshafts) that work together to keep the engine running smoothly. When mechanics mention valve train in their experience, they're talking about their ability to diagnose, repair, or maintain these critical engine components. This is a fundamental skill in automotive repair, similar to understanding brake systems or transmission repair.
