Fuel Injectors : Fuel Injection

A fuel injection system is a system for sending fuel into an engine. It is the most common and primary fuel delivery system used in todays automobiles, and replaced the older carburetor systems that existed during the 1980s and 1990s. The main difference between carburetors and fuel injection is that fuel injection atomizes the fuel by forcibly pumping it through a small nozzle under high pressure, while a carburetor relies on suction created by intake air rushing through a vent to send the fuel into the airstream. Modern fuel injection systems are designed specifically for the type of fuel being used. Some systems are designed for multiple grades of fuel (using sensors to adapt the tuning for the fuel currently used). Most fuel injection systems are for gas (Petrol) or diesel applications.There are several manufacturers of fuel fnjection systems and fuel injectors such as Bosch, Siemens etc.
