1302971 I. C. engine intake passages F-J RUNGE 24 March 1970 [24 March 1969] 14359/70 Heading F1B The inlet duct between a carburetter and the engine is arranged so that any gas blown out towards the carburetter is deflected in the inlet duct so that its direction is reversed and it reenters the inflowing inlet gas stream in a direction approximately parallel to it. Fresh gas is induced into an engine B from a carburetter A, in the direction AB, Fig.1, through a pipe 1 having a circular cross-section faired core 2. The core 2 is supported by stays 3 and may be movable axially for tuning purposes by a rod 6. The core 2 has a point at its end which faces the carburetter and a funnel shaped recess, which may carry a tapering point centrally, at the end facing the engine. Openings 4 deflect the gas entering the recess into the fresh gas stream in the direction AB. The annular gap between the pipe 1 and core 2 narrows in the direction AB. |
