Anthony Dember Auto Electrical Principles Electronic Fuel Injection In the mid 1970's, industrialized nations recognized the growing environmental threat that emissions from vehicles posed to the entire world. Governments started to regulate the amount of "acceptable" emissions (or amounts of unburned fuel) that vehicles could generate. Though developed much earlier in the twentieth century, fuel injection systems proved to be very helpful in reducing emissions. Other advancements, like the catalytic converter helped the job of car markers to create more environmentally friendly vehicles. Cutting down the amount of dangerous emissions from vehicles is one of the many benefits of electronic fuel injection engines. Other benefits include better control of power output for varying driving conditions, greater durability, and better fuel efficiency. The electronic fuel injection system replaced carburetors as the means of delivering fuel in precise amounts as the engine operates. There are different types of electronic fuel injectors found in automobiles and other vehicles, but it is the current mainstay for internal combustion engines. A carburetor mixes the fuel and air before the intake into the engine. This is called emulsifying the gasoline. An electronic fuel injection system injects the fuel into the engine while it is a liquid. When we think of the essential ingredients in the operation of an engine, we automatically think of fuel. However, air is essential as well, whether the fuel is emulsified or not. Air causes the fuel to be oxidized, which creates heat and in turn, enables the engine to run. The process of air delivery in an electronic fuel injection system is more efficient than a carburetor simply because the electronic fuel injection system's components are smaller. The fuel-to-air ratios - and how they
