Ford Focus Fuel Injectors, Fuel Rails & Components

In the mid-1970s, it became clear that the old way to supply fuel to the engine was no longer sustainable: on one hand, the oil crisis pushed automakers to look for more efficient technology, on the other hand, old carburetors proved to be responsible for increased pollution and became incompatible with the rising environment awareness. Engineers and designers rolled up their sleeves and developed the fuel injection system, to date the most common system to deliver fuel to the engine. Through the years, injection systems have become more complex and eco-friendly. Equipped with such a system and producing low CO2 emissions, the Ford Focus had just a few injection problems reported for almost 20 years.

At bottom, fuel injectors are valves that open and close several times per second according to the pistons' motion, atomizing the air-fuel blend directly into the cylinders or into the intake manifold. A pipe known as a fuel rail supplies fuel to the injectors. A control unit sends electrical signals to open the injectors in the right order and monitors their performance. Troubles with starting the engine, poor idle and performance, detonations are just the most common symptoms of bad fuel injectors, and they can lead to catastrophic engine failures. We offer a vast array of Ford Focus fuel injectors, fuel rails, and components skillfully built to deliver top performance for years to come.
