Direct gasoline injection (DI) is an advanced fuel delivery system used in modern internal combustion engines, where gasoline is injected directly into the combustion chamber rather than into the intake manifold. This method allows for more precise control of fuel delivery, improving fuel efficiency and power output while reducing emissions. DI systems can enhance engine performance by enabling higher compression ratios and optimizing combustion, resulting in better throttle response and overall engine efficiency.

CGI stands for Charged Gasoline Injection, which means the model's engine uses direct injection.
injection of fuel at high pressure is done directly into the cylinder where combustion occurs.

The Volvo V40 uses (among others) the 1.8 Mitsubishi GDI engine. GDI = Gasoline Direct Injection.
MPFI is Multi-Point Fuel Injection, which is the fuel system used with gasoline engines. CRDI is Common Rail Direct Injection, which is the fuel system used in diesel engines.
In modern gasoline injection systems, the fuel injector sprays gasoline directly into the intake manifold or directly into the combustion chamber, depending on whether the system is a port fuel injection (PFI) or direct fuel injection (DI) system. In PFI systems, the injector atomizes the fuel as it enters the intake manifold, mixing it with air before it enters the engine cylinders. In DI systems, the injector sprays fuel directly into the combustion chamber under high pressure, allowing for more precise fuel delivery and better combustion efficiency.
FSI stands for Fuel Stratified Injection. It is the name given to the proprietary Volkswagen and Audi direct injection, first used in the 2000 VW Lupo and now is used in all VW and Audi gasoline engines.
