The situation in development and use of fuel additives in [2001][2002][2003][2004][2005] was examined based on published and patent data. The basic types of additives that satisfy the increasing requirements for motor fuels were characterized. The additives market in Russia was especially examined. Production of modern fuels at Russian oil refineries is dependent on importing foreign additives to a great degree. However, in the last five years, domestic development of additives corresponding to the current level and capable of replacing imports has occurred. The most important promising directions in development of additives in the near future were formulated.

Endothermic phenomena were identified during the regeneration of the porous ceramic diesel particulate trap. These phenomena were experimentally investigated and they were found to be related to the cerium content of the fuel used for the trap loading and regeneration and to the soot mass accumulated in the trap. Carbon mass and energy balance through the regeneration process reveals that these phenomena cannot be attributed to chemical reactions in the trap. It is assumed that they are due to the effect of regeneration on the radial flow distribution through the trap, an assumption remaining to be experimentally tested.

The spray characteristics including spray droplet sizes, droplet distribution, spray tip penetration length, and spray diffusion angle directly affects the mixture process of fuel and oxygen and then plays an important role for the improvement of combustion and emission performance of diesel engines. Different injection rate shapes may induce different spray characteristics and then further affect the subsequent combustion and emission performance of diesel engines. In this paper, the spray and combustion processes based on four different injection rate shapes with constant injection duration and injected fuel mass were simulated in the software of AVL FIRE. The numerical models were validated through comparing the results from the simulation with those from experiment. It was found that the dynamic of diesel engines with the new proposed hump shape of injection rate and the original saddle shape is better than that with the injection rate of rectangle and triangle shape, but the emission of NO x is higher. The soot emission is lowest during the late injection period for the new hump-shape injection rate because of a higher oxidation rate with a better mixture between fuel and air under the high injection pressure.
