| Abstract: | The combustion emission characteristics andparticulate emission of diesel(P0), polyoxymethylene dimethyl ethers(PODE)/diesel (P10 and P20) were investigated at different injection pressuresand injection timings with a high pressure common-rail diesel engine. Resultsshow that the peak values of combustion pressure and heat release rate decreaseby the increase of PODE volume fraction. With the increase of injectionpressure, CO, Hydrocarbons(HC)and soot emissions of the three fuels decreaseobviously while NOx emission increases. The peak values of exhaustparticles number concentration decrease, among which the proportion ofaccumulation particles decrease while the proportion of nucleation particlesincreases. With the delay of injection timing, the NOx emission decreases, while the CO, HC， soot emissions andparticle number concentration increase. Compared with P0 and P20 fuels, the NOx emission and the particle geometric mean diameter (GMD) of P10 are lessaffected by the injection pressure and injection timing. |
