Sequential fuel injection is a type of ported fuel injection, yes.

SFI (Sequential Fuel Injection) also called as SEFI( Sequential Electronic Fuel Injection) . Unlike the Multi Point fuel injection (MPFI) system, SEFI has separate fuel injectors for each cylinder which inject fuel more precisely increasing the fuel efficiency.
you have a gas hoseline or other type leak. fix it!
sfi - sequential fuel injection efi - electronic fuel injection
the fuel injectors on a 1998 subran are located under the upper intake manifold this system is call the central sfi system
sequential fuel injection
No , SFI means Sequential Fuel Injection and OHV means that it is an Over Head Valve ( pushrod style engine )
sequential fuel injection , over head valve

Are you sure you have a carb? '07 Vipers have the 8.4L SFI engines, right? SFI being Sequential Fuel Injection..?
SOHC mean Single OverHead Cam Shaft,it is basically mechanism of controlling Valve of an automobile engine..cam shaft located at the head of cylinder.it pushes valve as per pre determined interval of time to facilitate entry of air-fuel mixer in to the cylinder.cam shaft is driven by crank shaft.previously cam shaft was side of cylinder block, now a days it is located in the head of cylinder.that is why it is called overhead. another type is DOHC-Dual OverHead Cam Shaft-where two cam shaft operate the valve opening and closing. however after entering of air-fuel mixure into the cylinder it burn. hence power is produce. SFI stands for Fuel Stratified Injection.it is advanced fuel injection system which facilitate to consume less amount of fuel during combustion (burning). basically now a days fuel is directly inject in to the combustion-chamber of each cylinder-engine.as oppose to curburator system.so SFI is the same system. engrmoinu@yahoo.com
they dont. they spray a vapor in to the cylinder (SFI) and the fuel is igniter by the spark plug
