syöttöpumppu

Syöttöpumppu, in English often referred to as a feed pump or injection pump, is a device used to transfer liquids, particularly fuels, into an engine or other mechanical systems. Its primary function is to deliver a precise amount of fluid at a specific pressure and time. In the context of internal combustion engines, syöttöpumppu plays a crucial role in the combustion process by supplying fuel to the cylinders.

There are various types of syöttöpumppuja, each designed for different applications and fuel types. Common examples include mechanical pumps, which are driven by the engine's crankshaft, and electric pumps, which are powered by the vehicle's electrical system. The design and operation of a syöttöpumppu are critical for efficient fuel delivery, which directly impacts engine performance, fuel economy, and emissions.

In diesel engines, the syöttöpumppu is particularly vital as it is responsible for both the fuel supply and the timing of injection, ensuring optimal combustion under high pressure. In gasoline engines, a syöttöpumppu is typically part of a fuel injection system, working in conjunction with other components to atomize and distribute fuel within the combustion chamber. Maintenance and proper functioning of the syöttöpumppu are essential for the longevity and reliability of the engine it serves.
