kaasujako

Kaasujako is a Finnish term that translates roughly to gas distribution or throttle distribution. In automotive and mechanical engineering contexts, kaasujako refers to how a throttle input is translated into the amount of air entering the engine and, accordingly, to the engine’s torque output. The concept encompasses both traditional mechanical linkages between the accelerator pedal and the throttle valve and modern electronic throttle control systems (drive-by-wire), where the engine control unit maps pedal position to throttle opening and fuel delivery. A proper kaasujako influences driveability, responsiveness, fuel efficiency, and emissions, and it is a key consideration in engine tuning and control software design.

Beyond automotive use, kaasujako can denote the distribution of a gaseous flow within a manifold or distributor, such as splitting gas among multiple branches or cylinders in a gas-handling or processing system. In Finnish technical literature and workshop discussions, the term appears in descriptions of engine management, throttle response, and performance adjustments, as well as in broader contexts where controlled gas distribution is essential.

Because the exact meaning of kaasujako depends on the system in question, it is typically defined by specifying the input control (for example, pedal position or signal) and the resulting gas flow or air intake. In practice, kaasujako is a general concept describing the relationship between control input and gas delivery.
