sisselaskesüsteemist

A sisselaskesüsteem (intake system) is a crucial component of an internal combustion engine responsible for delivering the necessary air and fuel mixture to the cylinders for combustion. The primary function of the intake system is to draw in ambient air, filter it to remove contaminants, and then either mix it with fuel before it enters the cylinders or deliver it to a fuel injection system.

The basic components of a typical intake system include an air filter, which prevents dirt, dust, and other debris from entering the engine, thus protecting internal components from wear. Following the air filter, the air often passes through a mass airflow sensor (MAF) that measures the amount of air entering the engine. This information is vital for the engine control unit (ECU) to determine the correct amount of fuel to inject.

In older engines or simpler designs, fuel might be mixed with air in a carburetor. Modern engines predominantly use fuel injection, where fuel is precisely metered and sprayed into the intake manifold or directly into the combustion chamber. The intake manifold itself is a component that distributes the air (or air-fuel mixture) to each cylinder. The design of the intake manifold, including its length and diameter, can significantly impact engine performance, affecting torque and power delivery across different engine speeds. Turbochargers or superchargers can also be integrated into the intake system to force more air into the cylinders, increasing power output.
