Definitions for fuel injection
This page provides all possible meanings and translations of the word fuel injection
fuel injection, fuel injection system(noun)
mechanical system to inject atomized fuel directly into the cylinders of an internal-combustion engine; avoids the need for a carburetor
the delivery, under pressure, of a metered amount of fuel, as a fine spray, into the intake airflow or combustion chambers of an internal combustion engine
Fuel injection is a system for admitting fuel into an internal combustion engine. It has become the primary fuel delivery system used in automotive engines, having replaced carburetors during the 1980s and 1990s. A variety of injection systems have existed since the earliest usage of the internal combustion engine. The primary 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 accelerated through a Venturi tube to draw 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. Most fuel injection systems are for gasoline or diesel applications.
