IC engine fuel vaporising improvement - crankcase pressure is fed to stationary turbine blades in carburettor and manifold junction (AR290875)

摘要

Air fuel mixture is assisted to vapourise by means of stationary turbine blades (15) fitted ina flange joint (9) between carburettor and inlet manifold. The flange contains a groove (10) which is hermetically sealed when the carburettor is in position. The groove has a number of equally spaced apertures running at a tangent to the intake axis and leading to the air intake. A union (14) connects the groove with an adjustable ball pressure valve situated in the feed pipe from the engine crankcase. Crankcase pressure enters the groove and mixes with the air fuel mixture. The stationary turbine blades impart a turbulence to the air intake.
