Merits of Fuel Injection in the SI
Engine
• Absence of Venturi – No Restriction in
Air Flow/Higher Vol. Eff./Torque/Power
• Hot Spots for Preheating cold air
eliminated/Denser air enters
• Manifold Branch Pipes Not concerned
with Mixture Preparation (MPI)
• Better Acceleration Response (MPI)
• Fuel Atomization Generally Improved
