초록
In this paper, we compare and analyze the injector defects of P-ENG and S-ENG with normal injectors by measuring current waveforms, voltage waveforms, exhaust gases and driving fuel economy. In the case of FTS failure, the S-ENG reduced the overall injection time by 3.7% and the main injection by 3.5% compared to the normal engines. In the case of AFS failure, the overall injection time increased by 45.7% and the main injection time increased by 24.1% compared to the normal engine. The rest data showed that fuel economy of S-ENG had 25.9% higher than P-ENG, NOX had 162.5% higher than that of P-ENG, and CO2 of S-ENG had 26.7% lower than P-ENG.
