ABSTRACT:
An economy throttle body for a single point fuel injection system is disclosed. The throttle body is formed from two integrally molded throttle body members. An upper member contains provision for the mounting two electronic solenoid injectors and an arrangement of fuel control passages while a lower throttle body member is utilized to mount the throttle body onto an engine manifold and contains the air induction bores and throttle assemblies of the system. Hot fuel handling capability is provided by a heat resistant thermal isolation seal separating the upper and lower throttle body members. Upwardly canted fuel delivery passages further enhance the hot fuel handling capability of the upper throttle body member.
