Edema has many possible causes: 1  Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. 2  Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
Cars with nitrous-equipped engines can be identified by the purge of the delivery system that most drivers perform prior to reaching the starting line. A separate electrically operated valve is used to release air and gaseous nitrous oxide trapped in the delivery system.
Example âAâ: Consider a nitrous system that features a nitrous solenoid with a .093â diameter orifice. If this solenoid is connected to 4 âFoggerâ nozzles, each with a #20 (.020â diameter orifice) jet, you have the following scenario: In this case, 4 #20 jets are equivalent to a single #40 jet.e sure that you select an adequate ground or your system will not operate correctly. 10. Connect the terminal marked âNOS 2â to one wire from the redundant or safety solenoid, with the yellow wire provided. 11. Connect the terminal marked âNOS 1â to one wire from the nitrous solenoid, with the green wire provided.
