All You Ever Wanted To Know About Fuel Injection

Fuel injection systems deliver fuel to the internal combustion engine. Fuel injection replaced carburetors in the early to mid 80's on most vehicles, becoming the primary fuel delivery system for the entire auto industry by the 90s.

While fuel injection is often thought of as a modern invention, there have actually been numerous fuel injection systems designed and produced since the very first use of the internal combustion engine. It was the advent of the affordable engine control module (aka on-board computer) that made mass adoption of fuel injection technically feasible.

What Makes Fuel Injection So Special?

Fuel Injection

Internal combustion engines need at least three things to function:

  • Fuel
  • Oxygen
  • Spark

When these things are combined, we get the explosion that all engines need to generate power. However, if we carefully mix the fuel with the air, and if we trigger the spark and just the right moment, we get maximum power and efficiency. This, in a nutshell, is what makes fuel injection so special. It allows for very high levels of precision that lead to great efficiencies.
