TBI was Used In vehicles of 1980s ….but soon replaced by (MPI)

Let’s Know How It works ..???

Separate injector for each cylinder

Sequential Fuel Injection

Also Called Sequential Port Fuel Injection (SPFI) or Timed Injection

How it Works…????

Each nozzle triggers fuel independently when spark starts…

SPFI sprays fuel exactly when intake valve opens

How the Work process takes place..???

15-20% Improvement in fuel

economy and performance

What Exactly The Injector Does ….?

Maximum Airflow

The maximum airflow and fuel mixture is delivered right into the cylinder in the form of

fuel spray

Pre-size Fuel Metering

Increased Power

Lower fuel consumption
