The effect of two-stage injection strategies on the soot formation of 0# fossil diesel were investigated experimentally using a constant volume combustion chamber. The ambient conditions was kept constant as injection pressure 150 MPa, ambient gas temperature 900 K, ambient gas pressure 45 bar. A high-speed diffused back-illumination extinction imaging technique was employed to make quantitative measurement on temporal soot evolution and reacting spray liquid length and a direct high-speed camera was used to measure the ignition delay. Two-stage injection strategies were varied with different pilot and main injection time, including a sweep of dwell time in pilotmain injection and pilot injection duration. The results show that the ignition delay decreases with the increasing dwell time. It may result from the entrained surrounding gas enhance the spray combustion process. In the reacting condition, the liquid-phase penetration is slightly longer with the shorter dwell time. However, the pilot injection duration shows slighter impact. The longer dwell time contributes to more total soot mass while the different pilot injection duration barely affect the total soot mass of the main injection. In non-reacting conditions, the spray of the main injection penetrates faster within a shorter dwell time investigated by Mie-scatter and CFD models [8]. When the two-stage injection duration are same, the second injection vapor phase penetration is longer and faster [9][10][11] [12]. For combustion characteristics, ignition delay of main injection is much shorter than that of the pilot injection and it may be shorter or longer with the dwell time increasing due to the different entrainment of surrounding gas [8]. In the multiple injection strategy investigation, the dwell time between injections and the pilot injection duration were seen as the two main factors. Seong-Young Lee et al. [13] found that it exists a slight reduction of the soot mass at the 0.3/0.65/1.2 ms condition. Fang et al. [14]measured the soot production of the biomass to liquid fuel using multiband flame measurement and two-color pyrometry. They found that the pilot injection results in a lower soot level compared with single injection with the same injection quality, while the pilot injection shown little impact on No. 2 diesel soot generation. However, in the study of [15], more fuel quantity during the first injection resulted in less soot emission with no increase in NOx emission when the pilot injection quantity is relative small to the main injection. Coupling the two factors, Carlucci et al. [16] found that both injection timing and duration show similar effect on the soot formation and oxidation. From the discussion before, in conslusion the soot formation in the multiple injection strategy isn't still precisely understanding. In this study, the ignition delay, reacting spray liquid length and total soot mass evolution of 0# fossil diesel were measured in a high-temperature high-pressure constant volume combustion chamber, the objective i...

Diesel engines are becoming more popular owing to their low fuel consumption and low emissions. The performance and emissions of diesel engines are strictly influenced by the injection pattern and the induced air quality. Utilization of diesel engines with mechatronic systems together with the advent of common-rail injection systems, which promotes the flexibility of injection control, has further increased diesel engine favourability and decreased the level of relevant emissions and noise. Development of mechatronic systems is a hierarchical procedure; in particular, in the case of common-rail diesel engine control, the extent and diversity of involved topics lead to a complex multi-stage development procedure. Many research studies have been carried out, thereby providing much literature in this field, which addresses different aspects of the development procedure for diesel engine management systems. Investigation of the existing literature will help researchers in the field to obtain a better understanding of the whole development procedure of diesel engine management systems and to make them familiar with new trends, state-of-the-art technologies and research fields. In this article, the control strategy development of common-rail diesel engine management systems is considered using the existing literature, i.e. the related literature was collected and categorized into the five main categories of modelling, sensitivity analysis, controller design, estimation and calibration. A brief description of every category followed by the relevant literature is given in the paper, and the common methods as well as the state-of-the-art techniques are discussed in each section. Finally, the strengths and weaknesses of the existing methods and the potential for further advancement are mentioned for each stage of the development of the engine management system, and a road map for the development of a common-rail diesel engine management system is presented.
