Advantages of EFI:
Uniform Air/Fuel Mixture Distribution
· Each cylinder has its own injector which delivers fuel directly to the intake valve. This eliminates the need for fuel to travel through the intake manifold, improving cylinder to cylinder distribution.
Highly accurate air/fuel ratio control throughout all engine operating conditions
· EFI supplies a continuously accurate air/fuel ratio to the engine no matter what operating conditions are encountered. This provides better driveability, fuel economy, and emissions control.
Superior throttle response and power
· By delivering fuel directly at the back of the intake valve, the intake manifold design can be optimized to improve air velocity at the intake valve. This improves torque and throttle response.
Excellent fuel economy with improved emissions control
· Cold engine and wide throttle enrichment can be reduced with an EFI engine because fuel puddling in the intake manifold is not a problem. This results in better overall fuel economy and improved emissions control.
Improved cold engine startability and operation
· The combination of better fuel atomization and injection directly at the intake valve improves ability to start and run a cold engine.
Simpler mechanics, reduced adjustments and sensitivity
· The EFI system does not rely on any major adjustments for cold enrichment or fuel metering. Because the system is mechanically simple, maintenance requirements are reduced.
