You engine mixes air with fuel in a process called fuel injection. This occurs within internal combustion engines. Most of the standard engines in vehicles made today are internal combustion engines. Fuel injection is the way fuel is delivered to the engine by your vehicle in order to be sure it continues running. The fuel injection system knows and makes sure the proper amount of gas is sent to your engine. Today, most engines meter the amount of fuel electronically. It used to be the case that fuel was metered mechanically.
Automobiles were constructed with carburetors installed to perform the task of the injection system before internal combustion engines were made. The fuel injector is not a large part of the vehicle. It consists of a nozzle and a valve, and is reliant on the power of a pump or pressurized container to inject the fuel into the engine.
Having a fuel injection system causes the car's engine to have a smoother response to the throttle transitions. Also, there is less worry about the engine starting because it is more reliable, and it increases fuel efficiency. Fuel efficiency increases because the fuel injection system improves fuel distribution from cylinder to cylinder. However, the more powerful an engine the less fuel efficient it will be. This is because there is more airflow necessary which in turn burns more fuel. This then creates more energy and thus creates more power in the engine.
Fuel injection performance kits can help reduce restriction in an engine by smoothing and straightening air flow. One of the leaders in production of fuel injection performance kits is K&N. They create a variety of kits to fit specific vehicles. These kits help enhance performance of the air intake in your vehicle and they are all street legal. With fuel injection being a major part of your car, it may be a good idea to research more on what it does and how fuel injection performance kits may be useful for your particular vehicle.
