The cylinder head is a crucial component of any internal combustion engine, including the popular 1.9 TDI. But what exactly makes it so vital, and what should you watch out for if issues arise? This article covers everything you need to know about the 1.9 TDI cylinder head.
What is a Cylinder Head and Why is it So Important?
As the name suggests, the cylinder head sits atop the engine’s cylinders and, along with the engine block, forms the combustion chamber. It houses critical components such as:
- Valves: Control the intake and exhaust of air and gases
- Camshaft: Controls valve movement
- Injectors (in diesel engines): Inject fuel into the combustion chamber
- Glow plugs (in diesel engines): Heat the combustion chamber for cold starting
A properly functioning cylinder head is essential for the engine’s performance, efficiency, and longevity.
