Electronic fuel injection systems use an electric fuel pump and pressure, rather than engine vacuum, to spray fuel into the engine intake manifold or combustion chambers. This allows for more precise fuel delivery and improved engine performance compared to carbureted systems. Modern systems are computer-controlled and use various sensors to monitor engine operating conditions and adjust fuel delivery accordingly through fuel injectors.
Fuel injection systems have replaced carburetors to meet stricter emissions standards. There are several types of fuel injection systems. Throttle body injection uses one or two fuel injectors in the throttle body. Multi-point fuel injection uses one injector per cylinder located at each intake port for more accurate fuel delivery. Sequential fuel injection improves upon multi-point by firing each injector just before the corresponding intake valve opens for better fuel efficiency and emissions control. Modern fuel injection systems precisely control fuel delivery through electronic management of injectors and sensors to maintain optimal air-fuel ratios.

Gasoline direct injection (GDI) is an engine technology that directly injects gasoline into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection which injects fuel into the intake port. GDI offers advantages like lower fuel consumption and higher output compared to MPI. It achieves this through an ultra-lean combustion mode and superior output mode enabled by its high pressure fuel injection system, optimized combustion chamber configuration, and other technical features. GDI engines have been shown to reduce fuel consumption by 15-20% and provide up to 5% more power compared to conventional MPI engines.

The engine control unit regulates fuel injection, ignition timing, and chooses between combustion modes - ultra lean burn, stoichiometric burn, and full power output. GDI engines can operate in either homogeneous or stratified charge modes. The homogeneous mode provides a nearly perfect air-fuel mixture for improved emissions control while stratified charge mode creates lean zones for higher efficiency.
The document discusses various auxiliary systems used in engines, including carburetors, fuel injection systems, ignition systems, and emission control systems. It provides details on the functions and components of carburetors, types of fuel injection systems, ignition components and systems. The document also covers emission standards and regulations including the Euro norms and BS standards in India for reducing vehicular emissions.

2. Basics of Common Rail System
What is Common Rail?
– Common Rail is a
– Electronic Controlled
– Diesel Fuel Injection System
Special Characteristics :
• Injection Pressure is produced and governed relatively
independent of the Engine Speed and can be selected freely
within a wide range.
• Injection begin and Injection Quantity can be freely selected
(EDC function)

6. Technology demands on FIE
• High pressure potential (> 2000 bars)
• Realization of the “ideal” rate of injection via pressure modulation alone
• Capability of realizing staged (boot) as well as pilot injection where pilot
is separated from the main injection
• Flexibility of selecting start of injection as well as end of injection
• Moderate initial rise of main injection
• Sharp cut off of the injection end
• Flexibility of selecting peak injection pressure
• Provide option to automatically change rate shape according to
engine speed and load
