Innsugningssystemet

Innsugningssystemet, also known as the intake system, is a crucial component in internal combustion engines. Its primary function is to deliver air, or an air-fuel mixture, to the engine cylinders for combustion. The system typically begins with an air intake point, which can be located in various positions on the vehicle to optimize airflow and minimize noise. From there, air passes through an air filter to remove particulate matter that could otherwise damage engine components or reduce performance.

Following the air filter, the air may travel through a mass airflow sensor (MAF sensor) which measures the density and volume of incoming air. This information is vital for the engine control unit (ECU) to accurately calculate the correct amount of fuel to inject. In some engines, particularly turbocharged or supercharged ones, the intake system includes an intercooler. The intercooler’s role is to cool the compressed air before it enters the engine, increasing its density and thus allowing more oxygen into the cylinders, leading to increased power output.

The intake manifold is the final component of the intake system before the cylinders. It distributes the incoming air or air-fuel mixture evenly to each cylinder port. The design of the intake manifold, including its runner length and volume, can significantly influence the engine's performance characteristics, affecting torque and horsepower at different engine speeds. A well-designed intake system contributes to efficient combustion, optimal power delivery, and reduced emissions.
