Abstract: Now a days we are facing a lot of problems with respect to fuel demand. A common problem in how to increase engine efficiency?, and how to manage the fuel economy?. Etc...so, the objective of this project work was to gain a better understanding of the efficiency characteristics of engine with inlet air pre heater. For this purpose, the effect of inlet air pre heater orientations, no.of testing, types of sophisticated fuel, types of material used for the purpose of inlet air pre heater. have been investigated. In the sample preparation the experimental setup designed with IAP. results shows that efficiency properties in terms, of mechanical efficiency, brake thermal efficiency, indicated thermal efficiencies are increased mainly depending upon the IAP orientations followed by the number of trails. Hence compared to without IAP the difference were not highly significant. The results indicate that the efficiency properties of engine setup with IAP is generally slightly greater than engine setup with out IAP setting. It may be due to thermal phenomenon like that convective heat transfer mode. it can be conclude that the order of efficiency properties of engine setup with IAP is greater than efficiency properties of engine without IAP. In addition, the efficiency difference were not highly significant.
