Gasoline Direct Injection (GDI) Explained: Power and Efficiency Unleashed
Gasoline Direct Injection (GDI), also known as Direct Injection, is a modern engine technology that has become the standard for internal combustion engines. Unlike traditional port fuel injection (PFI), which sprays fuel into the intake port, GDI injects fuel directly into the combustion chamber at extremely high pressure.
This allows for precise control over the fuel-air mixture. By injecting fuel directly into the cylinder, engineers can better manage the combustion process. This leads to several key benefits: increased power output (more air can be crammed into the cylinder without pre-mixing), improved fuel economy (less fuel is needed for a given power level), and reduced emissions. It's a key technology that has allowed manufacturers to downsize engines without sacrificing performance.
