Fuel Injector

Most people know very little about their automobiles. So to help with this, we are going to discuss a not so well known area of vehicles… Fuel Injectors. If your car is acting funny, and you are in need of a Colorado auto mechanic, there is no better place to go than to a certified AAMCO location.

Fuel Injector Systems

A Fuel Injection System is what allows fuel to be admitted into an internal combustion engine. In the past, vehicles used carburetors, but nowadays, fuel injectors have become the primary delivery system for fuel. Since their inception, numerous types have been created, and they are not all made equally.

The biggest difference between carburetors and fuel injectors is that a carburetor is dependent on the suction made by intake air to draw the fuel into the airstream. While a fuel injector atomizes the fuel by pumping it under high pressure through a small nozzle. Nowadays, fuel injection systems are created for specific types of fuel in mind. Some are made for various grades of fuel, while most are created to run gasoline or diesel.

Fuel Injector Objectives

As for many other things, the functions of a fuel injective system can vary dependent on their needs. Though, they all share one common task, which is to supply fuel to the combustion process. Beyond that, there are multiple objectives for different fuel injectors:

  • Power Output: Some fuel injectors specifically attempt to increase the amount of power that is output.
  • Fuel Efficiency: Fuel efficiency is important for vehicles that are primarily for transport, and not performance.
  • Emissions Performance: All street legal vehicles have to pass emissions tests. Though there are vehicles not meant for regular street use.
  • Accommodates Various Fuels: Certain vehicles have the ability to run different fuel types, so the fuel injector has to do the same.
  • Reliability: Some fuel injectors are designed to last so long as they are maintained, while others do not concentrate in that area.
  • Consistant Operation: The fuel injector needs to inject fuel consistently in order for the vehicle to maintain operation.
  • Initial Cost: Cost matters to some, and less to others. So some injectors are built solely for the essentials while others are specialized.
  • Repair/Maintenance Cost: Some injectors are easier to repair and maintain than others, it all depends on design.
  • Diagnostic Capability: When diagnostics are run, some fuel injectors do not have the means to be tested as well as others.

Fuel Injector Benefits

Driver Benefits: Depending on the type of fuel injector, drivers will notice a quicker and smoother response in their throttle transitions. Their engines will start in a more dependable manner. Vehicles will operate better in different temperatures and with higher fuel efficiency.

Environmental Benefits: As a rule of thumb, fuel injection systems greatly increase fuel efficiency, meaning less will be used for the same amount of power output. The exhaust emissions are generally cleaner as fuel injectors reduces the concentration of the toxic byproducts being emitted from the engine. Since the exhaust is more reliably consistant, exhaust cleanup devices such as a catalytic converter are able to be optimized better to be more efficient themselves.  Thus reducing toxins even further.

Hopefully this article helped to shed a little light on fuel injectors and their importance.
