Oil injection and EFI
Are there any professionals here that understand the operation of the oil injection system with EFI?
The oil injector nozzles have a check valve and air tube. The check valve is supposed to prevent air from "escaping" from the rotor or manifold. The other end of the air tube is connected to the throttle body. This would only allow air flow when the manifold or rotor is lower pressure than the point at the throttle plate... What function do the air tubes serve? Do they improve the spray pattern? Do they prevent siphoning oil during decel.? Is there a path from oil to air? :huh:
The picture below shows the air tubes for an S5 turbo, PN: 14-606 to 14-609, 14-616, 14-617
I've seen air tubes listed on all EFI rotaries...
