Imusarjaruiskutusjärjestelmän

Imusarjaruiskutusjärjestelmä, often referred to by its abbreviation, is a type of fuel injection system used in internal combustion engines. This system delivers fuel directly into the intake manifold, just upstream of each cylinder's intake valve. It's a successor to carburetors and earlier forms of single-point injection. The primary function of an imusarjaruiskutusjärjestelmä is to precisely control the amount of fuel delivered to each cylinder, ensuring optimal air-fuel mixture for combustion. This precise control leads to improved fuel efficiency, reduced emissions, and better engine performance compared to older technologies.

The system typically consists of a fuel pump, fuel filter, fuel rail, and multiple fuel injectors, one for each cylinder. An electronic control unit (ECU) manages the timing and duration of fuel injection based on various sensor inputs, such as engine speed, throttle position, and air mass. When the intake valve opens, the corresponding injector sprays a fine mist of fuel into the incoming air. This ensures that the fuel mixes thoroughly with the air before entering the combustion chamber. Modern imusarjaruiskutusjärjestelmät are highly sophisticated, allowing for dynamic adjustments to the fuel mixture under different operating conditions, contributing to the overall efficiency and responsiveness of the engine.
