Transcribed Image Text:Q2: A spark ignition engine has a swept volume of 2.0 liters, and operates on the
four-stroke cycle. When installed in the Rover vehicle, the operating point for a
vehicle speed of 120 kmh corresponds to 3669 pm, and a torque of 71.85 N.m, for
which the specific fuel consumption n 298 gkWh. Calculate the bmep at this
operating point, the arbitrary everall efficiency and the fuel economy (literw/100km).
If the air fuel ratio is 20:1, calculate the volumetric efficiency of the engine. The
calorific (heating) value of the fuel is 43 MJky, and its density is 795 kg'm'.
Ambient coniditines are 27 "C and 1.05 har.
