Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines.
GDI engine from a BMW car (fuel injector is located above the red triangle) Gasoline direct injection ( GDI ), also known as petrol direct injection ( PDI ), [ 1 ] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber .
Also Cummins PT (pressure-time) is a form of unit injection where the fuel injectors are on a common rail fed by a low-pressure pump and the injectors are actuated by a third lobe on the camshaft. The pressure determines how much fuel the injectors get and the time is determined by the cam.
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber.. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve, have mostly fallen out of favor to direct injection.
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine.
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

Sister-in-law's mechanic says the fuel injectors should be cleaned on her 2014 BMW 328 because of carbon buildup, at a cost of $307. Is it necessary?
The final car to use K-Jetronic was the 1994 Porsche 911 Turbo 3.6. Fuel is pumped from the tank to a large control valve called a fuel distributor , which divides the single fuel supply line from the tank into smaller lines, one for each injector.
