Süüteploks

Süüteploks is an Estonian term that translates to "ignition block" or "spark block." It refers to a component within an internal combustion engine, specifically in older or simpler engine designs, that houses the spark plug. In essence, it's the part of the cylinder head or engine block where the spark plug is screwed in.

The primary function of the süüteploks is to securely position the spark plug at the correct angle and depth within the combustion chamber. This precise placement is crucial for the spark to ignite the air-fuel mixture effectively at the optimal moment during the engine cycle. The design of the süüteploks also needs to withstand the high temperatures and pressures generated during combustion.

Historically, and in some smaller engines, the süüteploks might be a separate, sometimes even brass or cast iron, component that is threaded into the cylinder head. In more modern engine designs, the function of the süüteploks is often integrated directly into the cylinder head casting itself, meaning there isn't a distinct, separate block. However, the term can still be used to describe the localized area and threaded opening for the spark plug. The material and construction of the süüteploks are designed to be durable and resistant to heat and corrosion.
