Kütuseinjeksiooniga

Kütuseinjeksiooniga refers to a fuel injection system used in internal combustion engines. This technology delivers fuel directly into the engine's intake manifold or combustion chamber at precise intervals and pressures. Unlike older carburetor systems that relied on vacuum to draw fuel into the engine, fuel injection uses an electric pump to send fuel through injectors.

There are several types of fuel injection systems. Port fuel injection (PFI) injects fuel into the intake manifold just before the intake valve. Direct injection (DI) systems inject fuel directly into the combustion chamber, offering greater control over the air-fuel mixture and improved efficiency. Common rail direct injection (CRDI) is a specific type of direct injection used primarily in diesel engines, where fuel is maintained under high pressure in a common rail before being injected.

The primary advantages of fuel injection include improved fuel economy, reduced emissions, and enhanced engine performance. By precisely controlling the amount of fuel delivered, the system optimizes combustion, leading to more efficient use of fuel and cleaner exhaust gases. Fuel injection systems also contribute to smoother engine operation and better cold-start performance compared to carburetors. The implementation of electronic control units (ECUs) allows for real-time adjustments to the fuel injection based on various sensor inputs, such as engine speed, temperature, and throttle position.
