Experimental Studies on Performance Tests for Exhaust Turbocharged Diesel Engines (Part 1)

──Effects of Atmospheric Factors and Fuel Temperature on Engine Performance──

Abstract

We studied a test method to minimize the effects of environmental test conditions on engine performance and conduct a fairer test. In this report, we investigated the effects of fuel temperature and atmospheric factors calculated based on dry atmospheric pressure and intake air temperature on engine performance and emission gases in exhaust turbocharged diesel engines. As a result, it was clarified that differences in atmospheric factor influence the test results for engine power, specific fuel consumption, particulate matter, nitrogen oxide and carbon monoxide. There is a possibility of reducing variations in test results by maintaining constant atmospheric factors. Therefore, it is necessary to research this possibility.
