During coastdown testing of a family passenger car, the following road load drag force characteristic was derived: FRL = 0.392v²+162 Where FRL is given in Newtons, and v, the vehicle speed in m/s. It is desired that the vehicle should have a top speed of 200km/h. Assuming a transmission efficiency of 90%, which of the following engines would be most suitable? Type BMEP (Bar) Maximum Engine Cubic Capacity Speed (rpm) (CC) Normally aspirated SI engine 11 6500 1400 Turbocharged Sl engine 16 6000 950 Normally aspirated Cl engine 8.5 4500 2400 Turbocharged and aftercooled CI 12 4500 1800 engine

Select atleast two testing devices from among the categories (you may go beyond two). Discuss its application and methods of use. a. testing for speed (Tachometer), b. Testing of Air Consumption (Air-box method/viscous-flow meter), c. testing of exhaust smoke (Bosch/Hartridge/PHS), d. testing of exhaust emission (flame ionization detector/spectroscopic analyzers/gas chromatography) e. testing of torque (absorption dynamometer/transmission dynamometer).
