Very stupid question, but I have to ask, what is the fuel delivery system on a FD? I'm thinking mechanical fuel injection but not sure. Thank you for your patience (very stupid question.)

 

Anybody? I know someone has the awnser to this question.

 

electronic FI

 

Electronic fuel injection

Staged injection

Side feed injectors

550cc primary injectors

850cc secondary injectors

Fuel pump->fuel filter->fuel pulsation->primary rail->secondary rail->fuel pressure regulator->gas tank

 

^nice!

 

Well, are the injectors the same with piston engines (timed how long to be open for), because I thought that rotary engines needed a constant flow of fuel and air. Am I right? So I'm basiclly asking do thy stay open all the time?

 

same as a standard piston engine injector.

 

Here's a good description of the RX7 Fuel System

 

Oh. Cool. So it uses only the map sensor to get it's fuel readings. Is this right or does it have a maf sensor too?

 

No - it uses any number of sensors (air temp, engine temp, atmospheric pressure, O2. etc) to dermine which fuel "MAP" (a graph) to use. The MAP "sensor" tells it Manifold & Atmospheric Pressure.
