    THE WAY WE PROCEED...

  • INTRODUCTIONTransition of Fuel Supply System

  • ADVANTAGES OF FUEL INJECTION OVER CARBURETOR Fuel injection has no choke, but sprays atomized fuel directly into the engine.

    Electronic fuel injection also integrates more easily with computerized engine control systems.

    Multi port fuel injection delivers a more evenly distributed mixture of air and fuel to each of the engine's cylinders.

    Sequential fuel injection improves power and reduces emissions.

  • ELECTRONIC FUEL INJECTION Multipoint Fuel Injection Gasoline Direct Injection

  • MULTI POINT FUEL INJECTION SYSTEM Have a separate fuel injector for each cylinder .Have better cylinder to cylinder distribution.Eliminate the need to preheat the intake manifold

  • GASOLINE DIRECT INJECTION

  • WORKING OF GDI

  • MAJOR CHARACTERISTICS OF THE GDI ENGINE Lower fuel consumption and higher output

    Ultra-lean Combustion Mode Superior Output Mode

  • BASIC TECHNICAL FEATURES OF GDI ENGINE

  • COMPARISON WITH MPFI

  • In-cylinder Airflow

    Fuel Spray

    Optimized Configuration of the Combustion Chamber

  • Vehicle Fuel Consumption Fuel Consumption During Idling

  • Emission Control

  • ACHIEVEMENTSEngine performance Vehicle Acceleration

  • CONCLUSION

    As the GDI technology proved to be efficient in terms of fuel consumption and controlled emissions, the SI engines in near future will adopt this.The limitations for this technology being, initial cost of the system, increased service problem as it has many wearing parts and they generate more noise. Over coming the above drawbacks in near future one can see GDI SI Engines on roads.
