Experimental Studies on Performance Tests for Exhaust Turbocharged Diesel Engines (Part 2)

—Effects of Maintaining Constant Atmospheric Conditions on Engine Performance and Gas Test Results—

Abstract

This study aims to minimize the effects of environmental conditions on engine performance in order to improve the accuracy of performance tests. Previous studies have shown how variations in atmospheric factors, calculated based on dry atmospheric pressure and intake air temperature, influence the results of an exhaust turbocharged engine performance test. Therefore, we investigated the effects of maintaining constant atmospheric factors on engine performance and emission gases. The results show that variations in the atmospheric factors influence the engine power and specific fuel consumption.
