Abstract
This paper mainly studies on the performance of high-speed diesel engines and emission reduction when the engine uses heavy oil mixed with nanometer-sized additives Ce0.9Cu0.1O2 and Ce0.9Zr0.1O2. During the test, Indiset 620 combustion analyzer made by AVL, was used to make a real-time survey on the cylinder pressure, the fuel ignition moment, and establish a relation between the change trend of temperature in cylinder and the crank angle. For the engine burning heavy oil and heavy oil mixed with additives, combustion analysis software Indicom and Concerto were used to analyze its combustion process and emission conditions. Experimental investigation shows that nano-sized complex oxide can improve the performance of diesel engine fueled with heavy oil, and reduce the emission of pollutants like NOx and CO, comparing it with the pure heavy oil. According to the consequences of this experiment, the additives improve the overall performance in the use of heavy oil.
