Bensinsystemer

Bensinsystemer, often translated as gasoline fuel systems, are the complex networks within internal combustion engines responsible for storing, delivering, and injecting gasoline into the engine cylinders for combustion. The primary function of a bensinsystem is to ensure the precise mixing of fuel and air, a ratio crucial for efficient engine operation, power output, and emissions control.

Historically, bensinsystemer evolved from simple carburetors to more sophisticated electronic fuel injection (EFI) systems. Carburetors relied on the Venturi effect to draw fuel into the airflow, mixing it before it entered the engine. While simpler and cheaper to manufacture, carburetors offered less precise control over the fuel-air mixture, leading to lower fuel economy and higher emissions compared to modern systems.

Modern bensinsystemer predominantly utilize EFI. In an EFI system, a fuel pump draws gasoline from the fuel tank and delivers it under pressure to an injector rail. Electronic control units (ECUs), often referred to as the engine's computer, receive data from various sensors (such as oxygen sensors, throttle position sensors, and engine speed sensors) to calculate the optimal amount of fuel to be injected. This precise control allows for significant improvements in performance, fuel efficiency, and reduced harmful emissions.

Key components of a modern bensinsystem include the fuel tank, fuel pump, fuel filter, fuel injectors, fuel pressure regulator, and the ECU. These components work in concert to manage the fuel flow and ensure optimal combustion under varying engine operating conditions.
