HOW DOES FUEL INJECTION WORK?
Fuel injection replaced carburetion as the principal form of fuel/air delivery to vehicles in the mid 1980s. The simple, efficient design offered a new standard of reliability and efficiency by delivering fuel in varying volume and frequency - a process that would become more sophisticated as electronics replaced mechanical components within the injection systems.
With a petrol engine , fuel is transferred via an electronic pump known as fuel pump. This fuel subsequently passes through a filter that removes most contaminated that have entered (or corroded from ) the fuel tank.
This filtered fuel then enters one end of a common feeling tube for an engines fuel injectors called a fuel rail. The other end of this rail is met by a pipe that leads back to the fuel tank called a return pipe. This pipe contains a fuel pressure regulator (essentially a resistor or blockage) that ensures all fuel within the fuel rail is kept at a constant pressure ( essential for precise metering of fuel)
The engines injectors feed from this pressurised fuel delivery circuit.
