Sissepritsesüsteemidele refers to fuel injection systems, a crucial component in modern internal combustion engines. These systems are designed to deliver fuel into the engine's combustion chamber or intake manifold with precise control. This precision leads to more efficient fuel combustion, resulting in improved fuel economy and reduced emissions compared to older carburetor systems.

The primary function of a fuel injection system is to atomize fuel and inject it at the appropriate time and quantity into the engine. There are various types of fuel injection systems, including single-point injection (SPI), multi-point injection (MPI), and direct injection (DI). SPI systems inject fuel at a single point, usually in the intake manifold, while MPI systems inject fuel at individual intake ports for each cylinder. Direct injection systems, the most advanced, inject fuel directly into the combustion chamber.

Modern fuel injection systems are typically electronically controlled. An engine control unit (ECU) monitors various engine parameters, such as throttle position, engine speed, air temperature, and oxygen levels, and uses this data to calculate the optimal fuel delivery. Fuel injectors, which are electronically controlled valves, then precisely spray the fuel. This sophisticated control allows for dynamic adjustments to fuel mixture, adapting to changing driving conditions and engine loads. The widespread adoption of fuel injection systems has been a major factor in the advancements of engine performance, efficiency, and environmental compliance.
