Question 3 A 2L, 4-stroke, 4-cylinder petrol engine has a power output of 113.9 kW at 5500 rpm and a maximum torque of 235 N-m at 3000 rpm. When the engine is maintained to run at 5500 rpm, the compression ratio and the mechanical efficiency are measured to be 8.9 and 83.2%, respectively. Also, the volumetric efficiency is 93.1 %, and the indicated thermal efficiency is 43.76 %. The intake conditions are at 36.9 °C and 1.00 bar, and the calorific value of the fuel is 44 MJ/kg- Determine the Air-Fuel ratio in kg/kgf at 5500 rpm. Use four (4) decimal places in your solution and answer.
