kütusesisestus

Kütusesisestus refers to the process of delivering fuel into an internal combustion engine. This is a critical step for the engine's operation, as it directly impacts combustion efficiency, power output, and emissions. The method of fuel injection varies significantly depending on the engine type and design.

In older gasoline engines, carburetors were commonly used. These devices mixed air and fuel in a relatively crude manner before it entered the cylinders. Modern gasoline engines predominantly utilize fuel injection systems. These systems precisely control the amount of fuel delivered and the timing of its injection, leading to improved performance and fuel economy. Port fuel injection, where fuel is sprayed into the intake manifold, and direct injection, where fuel is injected directly into the combustion chamber, are two common types.

Diesel engines, on the other hand, rely on a high-pressure fuel injection system. Unlike gasoline engines, diesel engines do not use spark plugs. Instead, the high compression ratio heats the air to a temperature sufficient to ignite the injected diesel fuel. The precise control of fuel injection in diesel engines is crucial for achieving efficient combustion and minimizing particulate emissions.

The advancement of kütusesisestus technology has been a continuous process, driven by the need for greater fuel efficiency, reduced environmental impact, and enhanced engine performance. Modern systems often incorporate sophisticated electronic controls that monitor various engine parameters and adjust fuel delivery accordingly.
