Q6: A car traveling steadily on a level road at 100 km/hr requires about 15 kW of power from the engine. For the engine represented by the performance map in figure below estimate the fuel economy of the vehicle (km/g), the bore required of a four cylinder engine, and the maximum power the engine will produce. Assume that the engine is operating at its best fuel economy point when the vehicle is cruising at 100 km/hr, that engine controls limit the piston speed to 10 m/s, and that the performance map is size independent.

power from the engine. For the engine represented by the performance map in figure
below estimate the fuel economy of the vehicle (km/g), the bore required of a four
cylinder engine, and the maximum power the engine will produce. Assume that the
engine is operating at its best fuel economy point when the vehicle is cruising at 100
km/hr, that engine controls limit the piston speed to 10 m/s, and that the performance
