TL;DR: In this paper, the authors present an experimental investigation on the high-pressure diesel injection process of a common-rail injector under condition of varying pressures, particularly on the effect of the dynamic injection behavior on the fuel spray penetration.

TL;DR: In this article, an optical test rig is designed to observe the high-pressure methane jet into a constant volume bomb (CVB), and a numerical model is built to analyze the gas flow.

TL;DR: In this article, the effects of a high-pressure methane jet on the pilot ignited flame, using a constant volume bomb (CVB) test rig, were investigated, and it was shown that the interaction between the NG jet flow and pilot flame has a significant influence on the initial ignition and flame stability.

TL;DR: In this paper, a method for automatically identifying a diesel spray crushing process and automatically realizing the spray continuous calculation is presented, in which the sphericity degree and the average particle diameter of liquid phases in grids are calculated and taken as judgment bases, the information of particles in a flow field are calculated through a Lagrangian method, and information of the grids belonging to continuous liquid phase in the grid node information in the full-flow field is calculated by using an Euler model, and Euler block masses meeting two bases for determination are converted into particles and re-calculated
