Question

The following data were collected from a 4-cylinder compression ignition engine running on diesel fuel: Ne=2,250 rpm, mf=10.1 kg/hr, Hg=45,600 kJ/kg, De=2.2L, r=16, pime=1,050 kPa, and p1=100kPa. What is the dual-cycle efficiency of this engine? Use a βdc of 1 and a T3/T1 ratio of 9.

Answer #1

A naturally aspirated six cylinder, 6.128-L (374-in^3) diesel
engine consumes 21.9 kg/h (48 lb/h) of fuel and 440 kg/h (970 lb/h)
of air while running at 2400 r/min (rpm) and producing 93.8 kW (126
hp) of brake power. Assume the barometric pressure is 100 kPa (14.5
psi) and the ambient air temperature is 300 degrees K (540 degrees
R). A. Calculate the theoretical air consumption of the engine. B.
Calculate the volumetric efficiency. C. Calculate the air to fuel
ratio....
