Hom work عماد داود عبود (35) Q1 The Fiat Car has a four strok engine of 1089 C.C capacity.It develops maximum power 32kw at 5000 r.p.m. The volumetric efficiency at this speed is 75% and the air-fuel ratio 13:1, At peak power the theoretical air speed at the choke is 120 m/sec. The coefficient of discharge for the venturi is 0.85 and that of the main petrol jet is 0.66. An allowance should be made for the emulsion tube, the diameter of which can be taken as (1/2.5) of the choke diameter, the Petrol surface is 6 mm blow the choke at this engine condition. Calculate the size of a suitable choke (D) and main jet (d). The specific gravity of Petrol is 0.75 and the atmospheric pressure 1.03 bar and temperature 27°c. [D=23.2mm,d=1.296mm]
