Thank youA gasoline engine is at a location where the temperature is measured to be 14.2 °C and produces 347 KW at 5800 rpm while consuming 0.0184 kg's of fuel. During operation, data shows that its mechanical energy loss is 18 %, the actual volume of air going into each cylinder is 80% (the volumetric efficiency has a negligible variation), and the actual fuel-to-air ratio is 0.065. What were the engine parameters at sea level conditions if the pressure here is 100.3 kPa and the temeratur here is 18 Uc hotter than that of the alevated conditions? Determine at sea-level conditions the ISFC in ka/kW-hr Use four (4) decimal places in your solution and answer.
