Abstract

One of the main issues in internal combustion engines is the reduction of the flow of air into the cylinder and, consequently, the reduction of engine efficiency. To solve this problem, the turbocharger can be used as a proper device in diesel engines to increase the efficiency and performance of the engine. The turbocharger is located in the direction of the exhaust gases to compress the air during the process and direct it into the cylinders to increase the volumetric efficiency as well as more complete combustion to reduce the exhaust emissions. The simultaneous use of turbochargers and intercooler in diesel engines reduces the temperature of the intake air into the cylinder and increases the volumetric efficiency. In order to investigate the effect of turbocharger and intercooler on the operation of the Ferguson ۲۸۵ engine, a turbocharger with intercooler was used and installed on the engine, and then required tests carried out by hydraulic dynamometer in different speeds of ۱۰۰۰, ۱۵۰۰, ۲۰۰۰ and ۲۵۰۰ RPM at full load. The results showed that the engine torque at different speeds in the presence of turbocharger and intercooler increases by ۲۷.۲۲%. The results also indicated that the installation of turbocharger and Intercooler on a diesel tractor is meaningful in %۱ level at speeds of ۱۵۰۰ until ۲۵۰۰ RPM in this engine, so that the presence of a turbocharger and intercooler in the range above ۱۵۰۰ increase the engine performance. Also, the difference in temperature between the intercooler input and output shows that during higher speeds, the temperature difference is higher than the lower speeds, which contributes to the increase and improvement of engine volumetric efficiency.
