The biggest challenge is time, or lack thereof. Because fuel is being introduced directly into the combustion chamber, there are times in the 4-stroke engine cycle where you absolutely cannot safely inject fuel.

How High-Pressure Gasoline Direct Injection (GDI) Fuel Pumps Work
WebEDI, which injects fuel into the combustion process directly, is the most common internal uniform charging technique in the homogeneous charge engine. The EDI method produces high injection cylinders, which help to vaporize the fuel that has been injected early. A more uniform charge with a longer ignition delay period is therefore obtained. WebTypically, a high-pressure GDI pump creates about 2,000 psi. The sensor and the PCM help regulate the pressure to keep the fuel pressure at an ideal level for the engine in real time. When the in-tank pump sends fuel to the high-pressure GDI fuel pump, this is what happens: The low-pressure fuel enters through the top of the high-pressure GDI ... WebFeb 2, 2024 · It's called direct injection, and it refers to how the fuel makes its way inside an engine's controlled-explosion room, better known as a combustion chamber.
