ABSTRACT:
A throttle body for a rotary engine includes an electronically controlled single fuel injector with discharge pintle that is located above and between two counterrotating throttle valves with the fuel supply, rotor lubricating oil and idle air being directed through an orifice located below the injector. An atmospheric passage is interposed between the injector and the fuel supply orifice to serve as a vacuum break, through which a conical spray pattern is directed into the orifice which has walls contoured to receive the conical spray pattern and direct it in an unrestricted fashion as a spray cone into the intake manifold of a vehicle during low intake manifold vacuum conditions. The air passage serves to direct idle air through the orifice when throttle valves are closed to produce sonic mixing of idle air and fuel during operation of the engines at a high intake manifold vacuum.
