Utilization of the waste heat from internal combustion engines

Cooking devices could be evaluated for their performance using solar cookers as a bench mark. Accordingly, any device rejecting heat at 100°C and 80 W could be used for cooking. On this criteria diesel engine exhaust which rejects heat at 135–400°C and 3.8 kW is an excellent source. Methods of designing cookers to meet different end-purposes are discussed. Feasibility of cooking different types of food under exhaust gas temperature regimes is indicated.
