How do you maintain the efficient operation of your auto's fuel injection system? First, you need high-quality fuel injection parts. Failing ones should be immediately replaced with parts from the brand you can trust-Delphi. Among its great products are pumps and sensors. Automotive pumps and sensors are among those that usually fail first in a vehicle. But if you get a Delphi fuel pump or sensor, you can expect better performance and longer service life.
The fuel system's operation starts in the fuel pump inside the tank. This pump is a centrifugal force-driven device that circulates the fuel in the fuel lines and passages and into the injectors. The lines are usually called as fuel rails, and it is in these areas where fuel is pressurized. The fuel will then be collected by the fuel injector, which is actuated by a plunger. It's sprayed in the engine through a nozzle in each injector. Before the intake stroke, the injector must squirt the pressurized fuel as atomized mist.

The entire process is manned by sensors, a temperature sensor and a more modern MAP sensor. These are electronic devices that need to be maintained in their best condition to ensure that they'll provide accurate signals to the engine computer. The Delphi temperature sensor gives the right electrical output according to the temperature of air-fuel mixture while the Delphi MAP sensor accurately measures air pressure in the intake manifold for correct spark timing and fuel adjustment.
