Fuel Injection-Petrol

Originally, cars used a carburetor to get petrol into the engine. But when fuel injection came along, things changed: fuel injection, especially electronic fuel injection, produces fewer emissions and greatly increases fuel mileage. It’s all about getter a bigger ‘bang’ out of each teaspoon of fuel you use.

The main causes of fuel injector wear or failure is contamination of the fuel system and corrosion due to moisture in the fuel. Injector performance can be affected by very tiny particles. Fuel injectors perform an important role in the accurate metering and atomisation of fuel. These electro-mechanical valves react in milliseconds to open and close giving the electronic control unit optimal control over fuel flow to the engine.

Most fuel injectors are controlled by your car’s onboard computer. Fuel injection computers are part of a broader title called Programmable Fuel Management Systems. The computer has chips for memory, micro-relays to control actuators, a processor to run things, and a program to keep it all working smoothly. It looks to sensors to learn what environment the engine is operating in, it also looks at driver inputs to learn what you want to do. It processes the information it receives and calculates what the best fuel mixture and timing setting should be.

Fuel injection puts the kind of performance previously only found in professional racing cars and high-end models into the humblest of family run-arounds. A proper fuel injection system is a complicated piece of electronics that deliver fuel efficiently to your car’s engine.
