Bränsledatorn

Bränsledatorn, Swedish for "fuel computer," is a term often used in the context of older vehicles, particularly those from the 1970s and 1980s, to describe the early electronic control units (ECUs) responsible for managing fuel injection. These systems were a significant advancement over purely mechanical carburetors, aiming to improve fuel efficiency, reduce emissions, and enhance engine performance through more precise fuel delivery.

The bränsledatorn would typically receive input from various sensors, such as those measuring engine speed, throttle position, and sometimes air temperature. Based on these inputs, it would calculate the optimal amount of fuel to inject into the engine cylinders at any given moment. This was a departure from the fixed fuel-air mixture provided by carburetors, allowing for a more dynamic and responsive engine.

While rudimentary by today's standards, the bränsledatorn represented a crucial step in the evolution of automotive electronics. It laid the groundwork for the sophisticated ECUs found in modern cars, which control a multitude of engine and vehicle functions beyond just fuel delivery, including ignition timing, emissions control, and even transmission shifting. The development of these early fuel computers was driven by increasingly stringent environmental regulations and a growing demand for more fuel-efficient vehicles.
