Presentation on theme: "Induction Mr. Lombardi. Induction The term “induction” applies to the pathway for fuel and air to enter the combustion chamber. Including: – Carburetion."— Presentation transcript:
First Fuel Injection In 1910, Adams Farwell pioneered a non-carbureted fuel system called fuel injection, refined and adopted for diesel engines. But it wasn't until after World War II that thought was given to putting it on spark-ignited gasoline engines.
Fuel Injection Fuel injection atomizes the fuel by forcibly pumping it through a small nozzle under high pressure (15-90 psi). – Throttle Body Injection – Port Fuel Injection
Throttle Body Injection 1 or 2 Injectors for engine
Port Fuel Injection An injector per cylinder aimed at the port opening.
Direct Injection An injector per cylinder spraying inside the cylinder.
Intake Manifold “Wet” for Carbureted applications “Dry” for Injected applications Older manifolds were made from Cast Iron Modern manifolds are made from Aluminum Future manifolds will almost always be made of plastic (vinyl, phenolic resin, etc.)
