At the very heart of a car's operation is its engine. The blood and oxygen supply of this engine is the right type of fuel and air-fuel ratio used to power the vehicle. A complicated network of components and systems allow for the engine to receive the correct fuel mixture formation and facilitates the smooth running of a car. Incorrect fuel mixture formation or faulty component parts, such as the fuel injector, may impact the health of an engine negatively.
Apart from incorrect fuel mixture formation, an entire host of other factors, including residue build-up, overly rich fuel conditions, low oil levels and contaminated fuels, all lead to unhealthy engines. Problems with mixture formation have been tied to air leaks and low fuel pressure. Components of this system include air filters, air intake control valves, air supply breather hoses and fuel injectors.
The primary function of fuel injectors is to dispense fuel. Faulty fuel injectors can result in drivability issues and need replacing. There are a number of signs that indicate fuel injectors need attention. Restrictions, detonation (in turbocharged engines) and heat soak are some of the issues with faulty fuel injectors. Fuel injector problems are often caused by maintenance schedules not being met, these see to oil changes and filters being replaced.
