Frequent startups and shutdowns are anticipated for this system. Calculation Procedure 1. Determine the sources of waste heat available in the typical I-C engine There are three primary sources of waste heat available in the usual I-C engine. These are 1 the exhaust gases from the engine cylinders 2 the jacket cooling water 3 the lubricating oil. Of these three sources the quantity of heat available is in descending order exhaust gases jacket cooling water lube oil. Downloaded from Digital Engineering Library @ McGraw-Hill .
