kipinäpistokkeeseen

Kipinäpistokkeeseen is a Finnish term that translates directly to "spark plug" in English. It refers to the device in an internal combustion engine that ignites the air-fuel mixture. The spark plug's primary function is to generate a spark that initiates the combustion process, driving the engine's pistons.

The spark plug consists of a central electrode and one or more ground electrodes, separated by an insulator. A high-voltage current is sent from the ignition system to the central electrode. When this voltage reaches a sufficient level, it jumps across the gap between the electrodes, creating a spark. This spark ignites the compressed air-fuel mixture within the cylinder.

The design and condition of a spark plug are crucial for efficient engine operation. Worn-out or fouled spark plugs can lead to misfires, reduced fuel economy, and increased emissions. They are a consumable part of the engine and typically require periodic replacement as part of routine maintenance. Various types of spark plugs exist, differing in materials and design, to suit different engine types and performance requirements. Their proper functioning is essential for the reliable operation of gasoline-powered vehicles and other machinery that utilize internal combustion engines.
