What are the effects of chain elongation?
2 Answers
The symptoms of timing chain elongation include: engine vibration and incorrect ignition timing. Below is an introduction to the engine: 1. Introduction: An engine is a machine that converts other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816 and later improved by Watt into the steam engine. 2. Displacement: Let's first look at one of the most common engine parameters—engine displacement. Engine displacement is the total volume of all the cylinders in the engine, usually measured in liters (L). 3. Classification: Engines can refer to both power generation devices and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). Types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (used in racing cars), and electric motors.
I've dealt with numerous cases of chain elongation at the repair shop. The primary effect is a significant increase in engine noise, sounding like internal friction and knocking, especially noticeable during acceleration. When the chain loosens, it may skip teeth, causing incorrect ignition timing, resulting in sluggish acceleration and a sharp rise in fuel consumption. Worse still, if not repaired promptly, the chain can wear out the sprockets or even break, potentially damaging pistons and valves, leading to repair costs that can run into thousands. During routine maintenance, I always check chain tension and recommend inspecting it every 40,000 to 50,000 kilometers during oil changes to prevent these issues, ensuring peace of mind, effort-saving, and safety. Any unusual noises should prompt immediate attention from a professional.
