1. Suppose you drive a car for 630 km from Hamilton Toronto to Montreal. The car is a conventional internal combustion vehicle with parameters listed in the table below. You install a cargo box on the roof of the car to carry more stuff. The drag and mass parameters are listed below as well. a) Estimate the engine power [kW] on flat road at 110 km/h (14 marks) b) Estimate the additional energy [kWh] required of the engine for the cargo box, for the entire trip, assuming the trip was on flat ground and at constant speed. (7 marks) c) The engine has an approximate Brake Specific Fuel Consumption (BSFC) of 250 g/kWh. This tells you how much fuel you need to produce 1 kWh of energy at the engine output. Estimate the additional volume of fuel you needed just to carry the cargo box. (4 marks) Cd Parameter Value Car Mass 1250 kg 0.31 Af 2.7 m Fr 0.015 98% Mass Cargo box 22 kg nGearbox Frontal area 0.8 m Cd 0.27
