Fuel injection for internal combustion engines

Injectors are part of the fuel system and serve for mixing fuel with air in an internal combustion engine. This injection system has become the main delivery system for the fuel used in automotive petrol engines, having almost completely replaced carburetors in the late eighties. The injection system is designed and calibrated specifically for a particular type of fuel.

Systems with fuel injection can be of use both in gasoline and in diesel engines. With the advent of electronic fuel injection, hardware is improves in petrol and diesel vehicles. Firmware programmable fuel injection is a common hardware that can be used with various fuels.

Carburetor systems were used in gasoline engines before widespread use of fuel injection. Injection systems already existed in the earliest use of internal combustion engines.

The fuel injector is a valve that injects fuel coming from the fuel pressure pump, drawn from the tank. Functional purposes of the injection may be different. They all have one goal, which is to provide the fuel needed for combustion in the engine.

Some of these systems for fuel injection feature different design. Some of areas where these designs compete are: the power output, fuel efficiency, reliability, manageability and smoothness, initial cost, maintenance costs, diagnostic capability and correct tuning of the system.
