In this study, in order to analyze the characteristics of Gasoline Direct Injection Engines commercially available in Europe, 1.8L-class gasoline direct injection engine was chosen for the experiment, and the performance of the vehicle and its engine were analyzed. Experimental operation of the engine by chassis dynamometer are performed for a driving range of targets, and engine dynamo-experiment are performed at full load and partial load to study performance of the target engine. Experiment targets at the center of the engine cylinder head is equipped with spark plugs, and the turbocharger is applied to improve the power output. The engine was driving below 2500 rpm more than 90% of the vehicle testing time and the engine was operated at a load rate of less than 60%. In order to suppress exhaust gas temperature rise at full load, the engine drove with rich mixture at 3000 rpm and the above. BMEP was perceived by increasing the ignition timing and the two-stage fuel injection for partial load characteristics were observed above 12 bar of the BMEP. In addition, the combustion analysis was performed in this study. Excess air rate and emissions reduction efficiency were measured to characterize the test engine.
