kütusesöötmine

Kütusesöötmine refers to the process of delivering fuel to an internal combustion engine. This fundamental aspect of engine operation ensures that the correct amount of fuel is mixed with air for combustion. Historically, carburetors were the primary method for kütusesöötmine in gasoline engines, atomizing fuel and mixing it with intake air before it entered the cylinders.

In modern engines, especially those powered by gasoline, fuel injection systems have largely replaced carburetors. Fuel injection delivers fuel directly into the intake manifold or even directly into the combustion chamber under pressure. This allows for more precise control over the fuel-air mixture, leading to improved fuel efficiency, reduced emissions, and better engine performance across a wider range of operating conditions. Diesel engines have always relied on fuel injection, delivering diesel fuel directly into the highly compressed air within the cylinder, where it ignites due to the heat of compression.

The technology behind kütusesöötmine continues to evolve. Advanced electronic control units (ECUs) monitor various engine parameters such as engine speed, temperature, throttle position, and oxygen levels in the exhaust. Based on this data, the ECU precisely regulates the amount and timing of fuel delivery, optimizing combustion for different driving scenarios. This sophisticated control is crucial for meeting increasingly stringent emissions standards and maximizing the efficiency of modern engines.
