Take a good look at engine fuel consumption map. Explain the various different features of the graph/figure. Add a curve corresponding to 30 km/h per 1000 rpm to the existing figure and spot (approximately) the speed of 120 km/h. Consider this speed as top speed, and identify the corresponding engine rpm, bmep, engine torque and swept volume.
