Nozzle An electronic injector The injector in an electronic system is also held closed by a spring, but is opened by an electromagnet built into the injector body. The electronic control unit determines how long the injector stays open. Mechanical fuel injection Lucas mechanical fuel injection system Lucas mechanical fuel injection system In the Lucas system, fuel from the tank is pumped at high pressure to a fuel accumulator. From there it passes into the fuel distributor, which sends a burst of fuel to each injector, from where it is fired into the inlet port. The airflow is controlled by a flap valve which opens in response to the accelerator pedal. For cold starting, a choke on the dash or, on later models, a microprocessor control unit brings a special cold-start injector into operation, which injects extra fuel to create a richer mixture. Once the engine has warmed up to a certain temperature, a thermoswitch automatically cuts off the cold-start injector. Mechanical fuel injection was used in the s and s by many manufacturers on their higher-performance sports cars and sports saloons. A high-pressure electric fuel pump mounted near the fuel tank pumps fuel at a pressure of psi up to a fuel accumulator. This is basically a short-term reservoir that keeps the fuel-supply pressure constant and also irons out the pulses of fuel coming up from the pump. From the accumulator , the fuel passes through a paper element filter and then feeds into the fuel-metering control unit, also known as the fuel distributor.

It then signals the on-off valve ig the injector to open and squirt fuel into the inlet port. All this happens in a fraction of a second, the control unit responding instantly to changes in accelerator position, temperature and air pressure.

As well as improved control over fuel flow, the electronic system also operates at lower pressure than a mechanical system - usually at around psi. This makes it run more quietly than a mechanical system does. A typical system is the Bosch LJetronic, which is fitted to a wide range of European cars.

In this system, fuel is drawn from the tank by an electric pump. It is then fed straight up pipes to the injectors. The system pumps more fuel than is needed for injection - a loop circuit returns the excess to the fuel tank via a pressure regulator which keeps the pressure in the pipes constant.

The injector valves are held closed by springs, and opened by solenoids electromagnets when signalled to do so by the control unit. The amount of fuel injected depends on how long the solenoid holds the injector open. Engine management Some combined systems, known as engine management systems, can take into account many more factors than an electronic fuel injection system. One type, the Bosch Motronic, monitors the level of oxygen in the engine's exhaust gases.

When there is a deviation from normal, it can adjust both the ignition timing and the fuel delivery to bring the engine back to tune. This ensures that pollution levels are cut to a minimum as well as providing the best combination of performance and fuel economy.

Fuel-injected engine bay The underbonnet layout of a fuel-injected car tends to have a lot of pipework. This Audi engine bay clearly shows the reinforced braided fuel-injection-system pipes running over the top of the inlet manifold, and branching off to an injector at each manifold tract.

The "P" in the name refers to the actual fuel pressure that is produced by the gear pump. Secure PayPal checkout.
