In developing countries, a large number of old-generation diesel engines without turbochargers have become popular, and they are the main sources of power in the area of transportation. However, these types of engines have many disadvantages, such as low power and efficiency as well as a large amount of exhaust emissions. Meanwhile, these countries cannot immediately cease their image for them due to the limitations of budge for industry development. In this research, we promote a method to improve the efficiency of operation of old model diesel engines used for agricultural machines in Vietnam by retrofitting turbochargers. Consequently, the operating characteristics of retrofitted turbocharger engines have been performed both experimentally and using simulation. The research results show that the engine performance and exhaust emission improve dramatically when retrofitting suitable turbochargers corresponding with the engines. However, after turbocharging, we also increase the thermal and mechanical stresses of engines. The results indicate that we need to perform in detail to find the best solution for the stable operation of engines.
