This book is a an outcome of successful experimental research on stationary internal combustion engine waste heat recovery for useful purposes like cooking. It shall help the readers develop a practical understanding on the concept of utilization of available waste heat from abundantly used various internal combustion engines - stationary or in motion. Key Features: # Visual Display - The book has quite a number of pictures of the experimental set-up used for an easy understanding of the environment. # Heat-Load and Time-Temperature Relationships: The impact has been discussed elaborately with the help of numerous graphs with actual readings. # Emission Studies: An added study on impact on HC and CO emissions due to addition of exhaust heat recovery system is discussed based on actual observations.
