Environmental pollution caused by vehicles’ emissions has been one of the main contributions to climate change, a problem that has attracted significant global attention. Vehicles with diluted combustion engines and electric vehicles are both significant elements in the reduction of environmental pollution. To reduce environmental pollution from vehicle emissions, new vehicle technologies that optimize energy are being developed. One such technology is a sensor-aware exhaust gas recirculation (EGR) system, which measures excess air from diluted combustion engines. We performed experiments on a 1.5 L four-cylinder direct-injection turbocharged gasoline engine and compared the engine’s economic and emission characteristics with those of a combustion engine. The variation law of the influence of different diluted combustion technologies was applied to analyze engine performance. Results show that pollution levels from the two new diluted combustion technologies examined in our study are less than that of the original engine.Corresponding author: Christopher Chun Ki Chan
