Sisekasutuses

Sisekasutuses, also known as internal combustion, is a process where energy is released by the combustion of a fuel within a confined space, typically a cylinder in an internal combustion engine. This process involves the rapid burning of fuel, usually in the presence of oxygen, which releases heat and pressure. The energy released can be used to perform mechanical work, such as moving a piston in an engine.

The internal combustion process can be classified into two main types: spark-ignition and compression-ignition. In spark-ignition engines, such as those found in gasoline-powered cars, a spark plug ignites the fuel-air mixture. In compression-ignition engines, like those used in diesel engines, the heat generated by compressing the air in the cylinder ignites the fuel.

The efficiency of internal combustion engines is influenced by several factors, including the design of the engine, the type of fuel used, and the operating conditions. Modern engines often incorporate technologies such as turbocharging, direct injection, and variable valve timing to improve efficiency and reduce emissions.

Internal combustion engines are widely used in various applications, from automotive vehicles to power generators and marine engines. Despite advancements in alternative energy sources, internal combustion engines remain a significant component of the global energy landscape due to their reliability, cost-effectiveness, and versatility.
