Engine timing refers to the precise synchronization of the engine's components, specifically the crankshaft and camshaft(s). The crankshaft is responsible for the up-and-down motion of the pistons, while the camshaft controls the opening and closing of the valves that allow air and fuel into the cylinders and exhaust gases out. When the timing is correct, these events occur in perfect harmony, maximizing engine efficiency and power. However, if the timing is off, even by a small amount, it can disrupt the entire combustion process, leading to a variety of problems. Symptoms to look out for include reduced fuel economy, misfires, a noticeable lack of power, and unusual noises like knocking or pinging. Addressing these symptoms early can prevent significant engine damage. This is why understanding Engine Timing Issues: Symptoms and Why They're Critical is essential.
A Brief History of Engine Timing
