Põlemiskambers

Põlemiskambers, often translated as combustion chamber, refers to the enclosed space within an internal combustion engine where the fuel-air mixture is ignited and burned. This controlled explosion generates the high-pressure gases that drive the piston, ultimately producing mechanical work. The design of the põlemiskambers is crucial for engine efficiency, power output, and emissions control.

Key aspects of a põlemiskambers include its shape, volume, and the placement of the spark plug or injector. Different engine types, such as gasoline (Otto cycle) and diesel engines, have distinct põlemiskambers designs optimized for their respective combustion processes. In gasoline engines, the spark plug ignites a pre-mixed fuel and air charge, while diesel engines rely on the heat of compression to auto-ignite the injected fuel.

The shape of the põlemiskambers influences flame propagation and heat loss. A compact and smooth design generally promotes efficient combustion and reduces heat transfer to the cylinder walls. Factors like squish, tumble, and swirl are also carefully considered during design to ensure thorough mixing of fuel and air and rapid burning. The volume of the põlemiskambers, often referred to as displacement when combined with piston stroke, directly relates to the engine's power potential. Understanding and optimizing the põlemiskambers is a fundamental aspect of engine engineering.
