Air only is ad-mitted through the usual inlet valve which opens laterthan the suction operated valve. The rich mixture onlyis throttled. The air entering through the normal inletvalve fills the remaining space not filled by the mixture ofexhaust gases remaining in the clearance space, so thatthe compression remains constant. On the compressionstroke air is forced through the Venturi tube and mixeswith the rich gas in the bulb, causing considerable tur-bulence therein. With this arrangement a localized orstratified charge is obtained. Control is effected entire-ly by varying the quantity of mixture admitted. This principle was tried by Ricardo in a single cylin-der experimental engine of 5-i
