Recently, particle number concentration emitted by diesel internal combustion engine has focused on attention because the nano-sized particles are suspected being hazardous of air pollution as well as human body. In this study, by using the PPS (Pegasor Particle Sensor) system which can measure nano-particle from engine-out emissions, it is investigated the particle emission characteristic at various diesel engine-operating conditions. The PPS system operates by electro-statically charging particles passing through its body and then measuring the current produced by the charged particles as they leave the sensor. The particles are charged by ions generated by a corona discharge, which is generated around a sharp tip at high voltage. Under the steady state operation of the 2.0L CRDi diesel engine with different operating condition (1000,1500,2000 rpm), the nano-sized particle emission characteristic was measured at the downstream position of DOC system. According to this experiment result, more engine load increases, more particle concentration increases. Also, it has slowly become after installizing DOC.
