Question 8. What Are Mpfi And Tpfc Systems?

Answer :

MPFI stands for Multi Point Fuel Injection. In this gadget fuel is injected into the intake ports which is situated just upstream of each cylinder’s consumption valve. These systems are sequential systems, wherein injection is timed to coincide with consumption stroke of every cylinder. TPFC stands for temporary power gas control machine. In this kind of structures steady choke carburetor is used. The salient feature of this carburetor is that it presents jerk less engine raise. In those structures, throttle valve creates vacuum which opens the slide which controls the air gas ratio via a tapered jet.
