The movement is proportionalto engine speed (more RPM the greater the choke area). Attached to the piston is ajet, located in the bodyConstant depression or variable choke carburettors feature aa chamber via ataperedof the carburettor.which moves in and out of a fixedopenings, the piston rises and falls depending onvariations either side of the piston. The action of the tapered needle in the fuel jetallows more or less fuel to into the passing air therefore the fuel/airremains constant for improved economy and performance at all engineDuringspeeds. Task 8 - Induction SystemsIn order for combustion to take place an induction system is required to feed fuel and air into thecylinder of an engine. To improve efficiency and performance spark ignition (SI) engines are nowadopting compression ignition (CI) engine technology by injecting fuel directly into the cylinderjust before the point of ignition however these engines still require an air induction system.Carburettors: before fuel injection technology had been fully developed carburettors (carbs)were used to create a fuel/air ratio at different engine speeds and loads. A cold start facility wasalso fitted albeit manually operated.The demand for more performance has meant the fixed choke carb' was no longer suitable. Morecomplex carbs' were developed (twin choke) as well as variable choke (constant depression)carbs which used engine vacuum (during throttle opening) to vary the size of choke according tooperating requirements.
