Question

A four-Cylinder, four-stroke diesel engine develops 83.5 kW at 1800 rev/min ands a specific fuel consumption of 0.231 141W h, and air-fuel ratio of 23/1. The analysis of the fuel is 87% carbon and 13% hydrogen. and the is 43 500 kl/kg. The jacket cooling water flows at 0.246 kegs and its temperature rise is 50 K. The exhaust temperature is 316'C. Draw up an energy balance for the engine. Take R sa0.302 klike K and e, = 1.09 kl/kg K for the dry exhaust gas, and c, - 126 kJ/kg K for superheated steam. The temperature in the tat house is 17.8° C. and the exhaust gas pressure is 1.013 bar
