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,
Because the exact meaning of kaasujako depends on the system in question, it is typically defined by
