OK, you've bought your new car and the guys at the dealer said that your car has a fuel injection. Whaaa? Does it have something to do with those scary things at the hospital?
What is a fuel injection?
Fuel injection is a system made to replace the carburetor, which is considered less fuel efficient and too complicated. The carburetor's main job is to provide fuel for the valves from the fuel tank. Due to tougher requirements on cars that the carburetor couldn't handle, the fuel injection, which is smaller but offers more efficient burning was invented.
The first fuel injection was called throttle body fuel injection system (also known as single point or central fuel injection system). This system requires less modification on the engine so a car with a carburetor system could easily be converted into the injection system. The next generation was called multi-fort injection (also known as port, multi-point or sequential fuel injection). This system has a fuel injector for each cylinder, usually located in such way that they spray right at the combustion chamber. The injection system provides more accurate fuel metering and quicker response. This advanced system was developed along with the development of more sophisticated engines.
