What is the role of a GDI (Gasoline Direct Injection) system in modern engines?
A Gasoline Direct Injection (GDI) system delivers fuel directly into the combustion chamber at high pressure, rather than into the intake manifold as in traditional port fuel injection. This allows for more precise control over the fuel-air mixture, improving combustion efficiency and reducing emissions. GDI systems enable higher compression ratios, which increase engine power and fuel efficiency. They also offer benefits in terms of throttle response and cold-start emissions, making them a popular choice in modern, fuel-efficient vehicles.
