Harley Davidson is one of the most famous brands offering sports bike and other racing equipments. Harley fuel injectors are used for mixing air with fuel in the internal combustion system of the engine. It acts as a primary fuel division system which is used in automotive engines and replaced the use of carburettors in the year 1980. The injectors are designed on the basis of the fuel it will handle and manage. Most of them are specially prepared for diesel and gasoline whereas others are made for different kinds of fuels both gases and liquid. The basic difference between fuel injector and carburetor is that injector atomizes the fuel by pumping it through the nozzle with high pressure whereas the carburetor depends on low pressure. The Harley fuel injectors comprises of only nozzle and valve and the fuel injection power comes from a pressure container or pump attached at the back. There are different functional adjectives of the fuel system and it varies accordingly. 

Different objectives include power output, emission performance, fuel efficiency, reliability, initial cost, engine tuning, diagnostic capability, smooth performance and many other tasks. The operational benefits include smoother and dependable engine response during throttle transitions, dependable and easier engine starting, and excellent performance at low and high ambient pressure, increased fuel efficiency and maintenance intervals. One can control the operating conditions and can get desired performance, drive ability, fuel economy and emission. Fuel injectors increase the fuel capacity of the automobile. One can need lees fuel for better power output with improved cylinder to cylinder fuel distribution. A fuel injected engine creates more power than a carburetted engine. 

A typical Harley fuel injectors component include fuel pressure regulator, pump, injector, engine control module with digital circuitry and computer for communication between sensors and output, wiring harness, crank, MAF sensor, EGO and oxygen sensor etc. along with this there are different injection schemes which are used by different engines such as throttle injection, continuous injection, central port, direct and multi point fuel injection. Different injection type use different procedures and give different outputs. Depending on the car or bike model the injector and fuel injection procedure is used for better performance. Harley has different types of injectors which are used in large number of automobiles. Even modern petrol engines use direct injection method which provide more aggressive ignition timing and raises the performance.
