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
