초록

In this paper, we investigate the trend of injector waveform change due to failure of air flow sensor and intake air temperature sensor of CRDI engine. Changes in the injector opening time can be detected by the failure of the associated sensor, and the extension of the reaction time is closely related to fuel consumption. Thus, the proper maintenance time of the vehicle will affect the fuel economy and reduce the exhaust gas.
