- 摘要：
- Experiments were conducted on a 4-cylinder direct-injection diesel engine which has acompressing ratio of 19, using ultralow sulfur diesel blended with ethanol using 1–1.5%by volume of 1-dodecanol as the solvent to investigate the particulate emissions of the engine under five engine loads and at engine speeds of 1800 and 2400rev/min. Blended fuels containing 6.1%, 12.2%, 18.2% and 24.2% volume of ethanol, corresponding to 2%, 4%, 6% and 8%bymass of oxygen in the blended fuel, were used. At both engines peeds, with an increase in ethanol in the fuel,the smoke opacity, the particulate mass concentration and the total number of nano-size particles are all reduced. A diesel oxidation catalyst (Finnkat) was used and found to further reduce particulate emission. The smoke opacity, the particulate mass concentration and the total number concentration at 2400rev/min are higher than those at 1800rev/min.
