Abstract

Changes in altitude from the sea level have a significant effect on the performance of the internal combustion engine. Turbochargers can be used to maintain engine power by changing the height. In order to test the combination of turbochargers under the conditions of high altitude, the pressure and temperature should be created, which is possible by placing all the test set in the altitude simulator chamber, or at least the conditions of inlet and outlet must be controlled and the pressure and temperature associated with it altitude made. Creating these conditions is difficult to control. The purpose of this paper is to provide a simpler and more cost-effective way to create a r turbocharger test bed on an internal combustion engine in altitude conditions. In this paper, one-dimensional simulation engine is engineered and compared with the motor test results. Using a compression ratio, mass flow rate and corrected distances obtained from simulation, a simple method for testing the required pressure ratio at the desired height is presented. This preliminary design can specify the scope of turbocharger control overhead and reduce the cost and time of operational testing of the bird's device for extracting control overflow.The simulation of the target engine in the research and comparing it with the experimental results at different periods shows a maximum simulation error of 10%. This research is the applicable over a wide range of altitudes. The turbocharged motor is capable of maintaining 90% power up to a height of more than 12.2 km.
