The mechanical fuel injection diagram also shows the various mechanical components involved in the system, such as the throttle linkage, metering valve, and air control valve.. Throttle Body: The throttle body is a component that regulates the airflow into the engine. In some mechanical fuel injection systems, the throttle body may include a.. Mechanical fuel injection diagrams, particularly those illustrating the Lucas PI system, offer valuable insights into the complex interactions between fuel, air, and engine components. Understanding these diagrams is crucial for anyone involved in the maintenance, restoration, or performance tuning of classic vehicles equipped with this technology.

Function of Fuel Injection System. An engine fuel injection system ensures efficient combustion and optimal performance by delivering fuel in a controlled and precise manner based on the engine's operating conditions. Typically, it consists of an electronic control unit, a fuel pressure regulator, fuel injectors, and a fuel pump (ECU).. From 1980 onward, fuel injection became an alternative to carburetors on petrol engines. Well, the difference between fuel injection and carburetion is that fuel injection atomizes the fuel through a small nozzle under high pressure. Whereas carburetors rely on drawing fuel into the airstream through a venturi tube.
